Definitions
- the invention relates to a microscope with a wide-field illumination unit for illuminating at least a selected area of a sample.
- the microscope further comprises a camera detection unit for recording images of the selected area of the sample.
- Microscopes with a camera detection unit which in the following means in particular a detection unit which comprises a spatially resolving detector, are known from the prior art.
- the camera detection unit allows the detection process to be parallelized, since it can be used to create an image of a selected area of the sample in just one measurement.
- camera detection units do not have the time resolution and / or spectral resolution required for certain microscopy applications, such as, for example, fluorescence lifetime imaging microscopy (FLIM) or fluorescence correlation spectroscopy (FCS) .
- FLIM fluorescence lifetime imaging microscopy
- FCS fluorescence correlation spectroscopy
- a confocal microscope is known from US Pat. No. 6,867,899 B2 which comprises a light source for illuminating a sample and a spectrometer which detects detection light emanating from the sample.
- the microscope further comprises an acousto-optical deflector (AOD), which directs illuminating light emanating from the light source onto the sample and directs the detection light emanating from the sample into the spectrometer.
- AOD acousto-optical deflector
- the spectrometer is a point detector, i.e. a non-spatially resolving detector. An image of a selected area is obtained in several successive measurements with the spectrometer, i.e. serial, generated. Sometimes more high-resolution data is generated than is actually required.
- the microscope according to the invention comprises a wide-field illumination unit for illuminating at least a selected area of a sample and a beam splitter unit for generating a first detection beam path and a second detection beam path.
- the microscope further comprises a camera detection unit arranged within the first detection beam path for taking images of the selected area of the sample and a point detection unit arranged within the second detection beam path for detecting a predetermined partial area of the sample lying within the selected area.
- a detection lens is arranged on the object side of the beam splitter unit, which is provided as a common detection lens for the camera detection unit and the point detection unit.
- the camera detection unit can in particular be designed as a multi-channel camera or a color camera.
- the point detection unit can also comprise several detectors.
- the detector or detectors of the point detection unit can be one or more surface detectors which are used for point-by-point, ie non-spatially resolved, detection.
- several points of the selected area of the sample can be recorded simultaneously.
- the microscope according to the invention combines the advantages of the parallel-detecting camera detection unit with the advantages of the serial-detecting point detection unit.
- a camera detection unit is to be understood in particular as a location-resolving detection unit, while a point detection unit is to be understood as a non-location-resolving detection unit.
- the camera detection unit takes large amounts of images of the selected area quickly and without damaging the sample.
- the point detection unit quickly and with a high temporal and / or spectral resolution detects the predetermined partial area lying within the selected area.
- the microscope according to the invention can thus be used in particular for the efficient measurement of high-resolution spectra, for single-molecule analysis or in certain microscopy applications (such as FLIM or FCS).
- the microscope according to the invention also enables the targeted observation and tracking of dynamic processes and events. In the aforementioned applications, it is often not necessary to record the entire selected area of the sample with a high temporal and / or spectral resolution.
- point detection units are faster in the detection, for example, by the number of pixels of a comparable camera detection unit, since only a single pixel has to be read out per measurement.
- the point detection unit is preferably designed to carry out measurements at the MHz rate.
- the frame rate of a camera detection unit can generally be maximized in that only a few lines of a sensor element of the camera detection unit are read out. As a rule, however, the frame rate cannot be increased by reducing the number of columns to be read. Therefore, the maximum speed for camera detection units, here for example with a sensor element with 8 lines of 2500 pixels, is typically a factor of 20000 below the rate that can be achieved for a point detector with comparable electronics, ie in particular amplifiers and analog-digital converters can.
- Point detectors are largely insensitive to aberrations in the focus, which are induced in the detection beam path, for example by filters / beam splitter optics, since they only measure the light intensity and not its distribution. This increases flexibility and allows, for example, the use of inclined filters even in non-collimated parts of the beam path and thus space-saving and less expensive optics.
- the microscope comprises a control unit.
- the control unit controls at least the point detection unit as a function of the predetermined partial area of the sample and / or as a function of a predetermined point in time for a measurement that can be carried out with the aid of the point detection unit.
- the measurement controlled by the control unit takes place much more precisely with respect to the detection of the predetermined partial area of the sample and / or depending on the predetermined time than, for example, a manually controlled measurement.
- the control unit can in particular limit the predetermined sub-area of the sample, adjust an illumination intensity and / or adjust the wavelength, the wavelength range or the wavelength ranges of the light used to illuminate the sample or the predetermined sub-area of the sample. Furthermore, the control unit, in particular when the microscope is used for FLIM measurements, can synchronize a pulsed illumination with a detection by the camera detection unit and / or the point detection unit, i.e. a detection and / or control of the points in time of the emission of an illumination light pulse and, in particular, time-resolved detection of a fluorescence signal.
- the predetermined partial area of the sample and / or the predetermined point in time is stored in the control unit in a preset manner.
- the predetermined partial area of the sample and / or the predetermined time can be entered, for example, by an operator.
- the images of the selected area of the sample recorded by the camera detection unit can serve as the basis for the input of the predetermined partial area and / or the predetermined time.
- the operator can select an interesting partial area (“region of interest”, ROI) within one of the images recorded by the camera detection unit as a predetermined partial area.
- the microscope comprises an image processing unit coupled to the control unit.
- the image processing unit determines the predetermined partial area of the sample and / or the predetermined time based on at least one of the images recorded by the camera detection unit, and provides the predetermined partial area of the sample and / or the predetermined time for the control unit for controlling the point detection unit ready.
- the image processing unit allows a faster and more precise determination of the predetermined partial area of the sample and / or the predetermined time than, for example, a manual determination by the operator.
- the image processing unit can in particular be an intelligent image processing unit, ie a unit which, for example, has learned, in particular using a machine learning method, in which sub-area of the sample a detailed measurement is worthwhile. Furthermore, it is advantageous if events, for example the expression of a specific protein, can be determined by the user before a time series measurement. The expression can be expressed in particular by the increase in the fluorescence signal measured at a specific point. These events can serve as triggers for detection with the point detection unit in a specific partial area of the sample.
- the image processing unit can in particular also have been trained to react to certain events, for example the aforementioned expression.
- the camera detection unit is designed as a multi-channel camera or color camera.
- the control unit for dyes.
- Such a separation is also referred to as "spectral unmixing".
- the separation of the data recorded with a multi-channel camera by means of "spectral unmixing" is in principle also possible without further information, but the number of channels in a camera-based detection is usually limited to 3 to 4 channels.
- the beam splitter unit is formed by a mirror element that can be switched by the control unit.
- the switchable mirror element is designed in such a way that, in a first switching state, detection light emanating from the sample is directed onto the camera detection unit, and that in a second switching state the detection light emanating from the sample is directed onto the point detection unit .
- a simply constructed beam splitter is realized, which mechanically allows detection to be carried out either with the camera detection unit or the point detection unit.
- the pixels that are missing in the image captured by the camera detection unit can be supplemented in particular by the detection of the point detection unit.
- the mirrors have the micromirror each have a lower mass than, for example, a single galvanometer mirror, as a result of which the beam splitter unit formed by the micromirror actuator unit can be switched more quickly.
- the switching of the micromirror actuator unit can take place within a few microseconds and below, so that a quick point-resolved Measurement by means of the point detection unit at one point or in several areas of the sample is also possible during a single exposure time of the camera detection unit.
- the micromirror actuator unit consists of a large number of switchable micromirrors that are a few micrometers in size and can be controlled individually. Each micromirror is designed such that in a first switching state it directs detection light emanating from the sample onto the camera detection unit and in a second switching state it directs the detection light emanating from the sample onto the point detection unit.
- the beam splitter unit is formed by a neutral beam splitter (neutral beam splitter), a polarization beam splitter (polarizing beam splitter) or a dichroic mirror.
- the beam splitter unit has no mechanically movable components and is therefore less prone to errors.
- the use of such a beam splitter unit is associated with low manufacturing costs.
- the detection light can be split up according to colors (dichroic mirror) and / or the polarization directions (polarization beam splitter).
- the microscope comprises a first tube lens.
- the first tube lens is arranged between the detection objective and the beam splitter unit and is shared by the camera detection unit and the point detection unit.
- This further development is particularly space-saving, since here the need for separate tube lenses arranged on the image side of the beam splitter unit in the first detection beam path and the second detection beam path is eliminated.
- the microscope comprises a first tube lens and a second tube lens.
- the first tube lens is arranged between the beam parts purity and the camera detection unit.
- the second tube lens is arranged between the beam splitter unit and the point detection unit.
- the point detection unit comprises a tilting mirror which can be controlled by the control unit and which is arranged on the image side of the beam splitter unit in the second detection beam path.
- the control unit controls the tilting mirror in particular in such a way that at least part of the detection light emanating from the predetermined partial area is detected.
- the predetermined partial area can be scanned in several successive measurements and recorded completely serially.
- the point detection unit comprises a micro-mirror actuator unit (DMD) which is different from the beam splitter unit and can be controlled by the control unit and which is arranged on the image side of the beam splitter unit in the second detection beam path.
- DMD micro-mirror actuator unit
- Each micromirror of this micromirror actuator unit is designed such that it directs detection light emanating from the sample in a first switching state along the second detection beam path to a detection unit and that in a second switching state it directs the detection light emanating from the sample, for example to an absorber or another detection unit .
- the micromirror actuator unit is preferably arranged in a plane conjugate to the image plane of the camera detection unit.
- the point detection unit is designed such that detection light emanating from the predetermined partial area of the sample is detected in a spectrally resolved manner.
- the point detection unit can comprise a fiber-coupled spectrometer. In addition to generation, this allows high-resolution spectral data, in particular also the identification in the fluorophores overlapping in front of a certain sub-area, which is not possible with the camera detection unit alone.
- the wide-field illumination unit is designed to generate a light sheet.
- the light sheet With the help of the light sheet, thin layers of the sample can be illuminated and excited to fluorescence. As a result, a higher resolution is achieved than with other methods for wide field lighting.
- the detection objective is designed as an illumination objective of the wide-field illumination unit.
- the microscope can be designed to be particularly space-saving. Such arrangements are used in particular in oblique plane microscopy (OPM) and in swept confocally-aligned planar excitation (SCAPE) microscopy.

- Detection unit and a point detection unit Detection unit and a point detection unit.
- FIG. 1 shows an embodiment of a microscope 10a.
- the microscope 10a comprises a wide-field illumination unit 12, a beam splitter unit 16, a camera detection unit 22, a point detection unit 24 and a control unit 28.
- the wide-field illumination unit 12 comprises a light source 40, an illuminating lens 42 and a deflecting mirror 44.
- the light source 40 generates illuminating light from which a light sheet lying in the object plane is generated with the aid of the illuminating lens 42 and the deflecting mirror 44.
- the light sheet illuminates at least a selected area of a sample 14.
- the illuminating light is preferably light which excites fluorophores in the sample 14 to fluoresce / phosphoresce.
- the camera detection unit 22 is designed in particular as a multi-channel camera or color camera and is arranged within the first detection beam path 18.
- a first tube lens 32 is arranged between the beam splitter unit 16 and the camera detection unit 22. As a result, an arrangement for recording images of the selected area of the sample 14 is realized in the first detection beam path 18.
- the point detection unit 24 is arranged within the second detection beam path 20.
- the point detection unit 24 comprises a controllable tilting mirror 36, a detector 46 and further optical elements, which are generally referred to here with the reference symbol 48, such as (pinhole) diaphragms, filters or lenses.
- a (perforated) diaphragm can be arranged in front of the detector 46. Detection light assigned to individual points or point-like regions on the sample 14 can be directed onto the detector 46 by means of the tilting mirror 36.
- the detector 46 is designed to use the second detection beam path to detect a falling detection light with high spectral resolution and / or time.
- the detector 46 is formed by a fiber-coupled spectrometer or an avalanche photodiode ("APD").
- the detector 46 can also be formed by a dispersive element which spectrally splits a light beam incident in the point detection unit 24 and one off Several detector units existing arrangement for detection of the spectrally split light beam can be formed.
- a second tube lens 34 is arranged in the second detection beam path 20.
- an arrangement for serial detection of the predetermined area is formed in the second detection beam path 20, as it were with a confocal microscope.
- the detection objective 26 and the second tube lens 34 form in the exemplary embodiment shown a system of two lenses at a distance from their focal lengths, which is also called the 4f system.
- a 4f system is telecentric and therefore has positive imaging properties, for example the magnification does not depend on the distance between the object plane and the image plane.
- the beam splitter unit 16 defines an interface between two media, for example glass and air, which is tilted relative to the normal to the optical axis, and is therefore arranged within this infinite beam path. The arrangement in the infinite beam path prevents the occurrence of aberrations.
- beam splitter unit 16 is arranged in a non-collimated beam path and therefore the light transmitted (and thus blocked) by the beam splitter unit 16 onto the point detection unit 24 which is insensitive to aberrations.
- beam splitters in an infinite beam path can be configured as plates, while in non-non-infinite beam paths (focused or defocused light bundles) they are advantageously realized as cubes in order to avoid aberrations.
- An exception to this is shown in FIG. 4.
- Beam splitter plates typically have advantages over beam splitter cubes in terms of their spectral splitting properties and are often also less expensive.
- the detection objective 26 and the second tube lens 34 do not form a telecentric 4f optics.
- the detection lens 26 is corrected in such a way that light, which comes from a plane of the detection lens 26 on the sample side, is sharply imaged onto a detector in cooperation with an appropriately positioned tube lens, but this light is not runs collimated between the detection objective 26 and the second tube lens 34.
- the sample-side plane shown is not congruent with the definition plane of the detection objective 26. Further alternative embodiments are conceivable. It is crucial that no focus is formed between the detection objective 26 and the second tube lens 34.
- the lenses 48 form a telecentric 4f optics. This ensures that no aberrations are induced by the tilting mirror 36.
- the control unit 28 is designed such that the predetermined partial area of the sample 14 and / or a predetermined point in time (for example the point in time of an interesting biological event in the sample 14) can be stored in the control unit 28 for a measurement with the point detection unit 24 .
- the predetermined partial area and / or the predetermined point in time can be entered into the control unit 28 by an operator.
- the control unit 28 further comprises an image processing unit 30, which is designed the predetermined partial area of the sample 14 and / or to determine the predetermined time for the measurement with the point detection unit 24 and to provide it for the control unit 28.
- the control unit 28 is also connected to the camera detection unit 22 and the beam splitter unit 16 and designed to control them. In particular, the beam splitter unit 16 can be controlled in order to change filters flexibly and automatically, for example for certain image areas.
- the determination of the predetermined partial area of the sample 14 and / or the predetermined time for the measurement with the point detection unit 24 by the operator and / or the image processing unit 30 takes place in particular on the basis of the images of the selected area recorded by the camera detection unit 22 of the sample 14.
- the image processing unit 30 can identify pixels in the images recorded by the camera detection unit 22, in which different fluorophores overlap, and determine them as a predetermined partial area. With the aid of the point detection unit 24, a spectrally resolved measurement can then be carried out, which allows the fluorophores of the predetermined partial area to be clearly identified.
- Physiological or neurological events taking place in the sample 14, for example, which are identified by the image processing unit 30, can serve as the basis for determining the predetermined point in time.
- the control unit 28 controls the tilting mirror 36 of the point detection unit 24 and the wide-field illumination unit 12 as a function of the predetermined partial area of the sample 14 and / or the predetermined point in time for the measurement with the point detection unit 24.
- the control unit 28 detects the Tilting mirror 36 of the point detection unit 24 is controlled in such a way that the entire predetermined sub-area of the sample 14 is detected with the point detection unit 24 in successive measurements.
- the point detection unit 24 is controlled, for example, by the control unit 28 in such a way that by changing the diameter of a pinhole the size of a region scanned in a measurement, in particular point or circular, is changed, via which a detector of the point detection unit 24 is integrated.
- the control unit 28 can also control, for example, the wavelength of the illumination light generated by the wide-field illumination unit 12.
- the combination of a point detector and light sheet lighting opens up new freedom.
- the numerical aperture of an illuminating beam defines the distribution of the illuminating light.
- the illuminated area can e.g. not simply enlarged. This would require a dimming or a reduction of the numerical aperture of the lighting and, along with this, an undesired extension of the depth of field of the lighting focus.
- this could also be achieved by increasing the diameter of a pinhole of a point detector used in conventional point-scanning confocal microscopes.
- the depth of field of the detection deteriorates significantly. Illumination with a light sheet is therefore an important component in increasing the freedom when scanning with the point detection unit.
- a measurement integrated over a larger area of the sample by means of a detector can, for example, increase the sensitivity and / or the temporal resolution of the measurement.
- FIG. 2 shows a further exemplary embodiment of a microscope 10b.
- the exemplary embodiment shown in FIG. 2 differs from the exemplary embodiment shown in FIG. 1 in that the point detection unit 24 has a micromirror actuator unit 38 (“digital mirror device”, DMD) instead of a controllable tilting mirror 36.
- DMD digital mirror device
- the micromirror actuator unit 38 is arranged on the image side of the beam splitter unit 16 in the second detection beam path 20 in a plane conjugated to the image plane of the camera detection unit 22.
- the micromirror actuator unit 38 consists of a large number Switchable micromirrors which are a few micrometers in size and can be controlled individually, for example by the control unit 28.
- Each micromirror of the micro mirror actuator unit 38 is designed such that in a first switching state the detection light emanating from the sample 14 is directed onto the detector 46, and that in a second switching state the detection light emanating from the sample 14 is directed onto an absorber.
- the detection light beams 20 collide with the detector 46.
- two points are not imaged on the detector 46, but two collimated beam paths tilted against one another hit the detector 46.
- the detector 46 thus integrates the signal via the points selected by the micromirror actuator unit 38 .
- the micromirror actuator unit 38 lies in a plane conjugate to the focal plane of the detection objective 26.
- FIG. 3 shows a further exemplary embodiment of a microscope 10c.
- the exemplary embodiment shown in FIG. 3 differs from the exemplary embodiment shown in FIG. 1 on the one hand in that the beam splitter unit 16 'is formed by a micromirror actuator unit controlled by the control unit 28.
- the wide-field illumination unit 12 includes, in addition to the light source 40, a cylindrical lens 50 for generating a light sheet.
- Each micromirror of the micromirror actuator unit forming the beam splitter 16 ' is designed in such a way that, in a first switching state, detection light is emitted by the sample 14 goes out, is directed to the camera detection unit 22 ', and that in a second switching state the detection light emanating from the sample 14 is directed to the point detection unit 24.
- the individual pixels of the images recorded by the camera detection unit 22 ' can be directed into the point detection unit 24 in a targeted manner.
- the predetermined sub-area can thus be completely captured in one or more measurements, regardless of its concrete geometric shape.
- Figure 4 shows a further embodiment of a microscope 10d.
- the beam splitter unit 16 generates the detection light from the sample 14 by reflection, the first detection beam path 18 and the second detection beam path 20 by transmission.
- the aberrations induced by the transmission are for measurement with the point arranged in the second detection beam path 20
- Detection unit 24 is not critical. This arrangement eliminates the need for a separate tube lens arranged on the image side of the beam splitter unit 16 (i.e. the tube lenses 32, 34 for each detection beam path 18, 20 of the microscopes 10 according to FIGS. 1 and 2 are omitted here).
- the only tube lens 32 is arranged between the beam splitter unit 16 and the detection objective 26.
- FIG. 5 shows a further exemplary embodiment of a microscope 10e.
- the microscope 10e shown in FIG. 5 differs from the microscope 10a shown in FIG. 1 essentially in that the point detection unit 24 comprises a first detector 46a and a second detector 46b.
- the same or equivalent elements are denoted in FIGS. 1 and 5 with the same reference numerals.
- the micro game actuator unit 38 of the point detection unit 24 is designed such that If individual micromirrors of the micromirror actuator unit 16 are switched, the detection light, which is assigned to individual pixels of the images recorded by the camera detection unit 22, can optionally be directed onto the first detector 46a or the second detector 46b.
- the point detection unit 24 thus enables the simultaneous detection of several points.
- Embodiments of the invention make it possible to combine the strengths of a camera detection with those of the point detection in a single microscope 10.
