Definitions
- the invention relates to a light sheet microscope, with a detection lens for imaging a target area of a sample, which is located in a focal plane of the detection lens, an illumination lens for focusing an illuminating light beam into the sample.
- the detection lens and the lighting lens face each other, and the optical axis of the detection lens and the optical axis of the lighting lens are parallel to each other.
- the light sheet microscope further comprises a first light deflecting device with at least a first deflecting surface and a second deflecting surface, which are arranged and formed in each case offset to the optical axis of the detection objective, the illuminating light beam focused by the illumination objective in a direction perpendicular to the optical axis of the detection objective in such a way to redirect that the deflected illuminating light bundle forms a light sheet-like illuminating light distribution focused in the focal plane.
- a first light deflecting device with at least a first deflecting surface and a second deflecting surface, which are arranged and formed in each case offset to the optical axis of the detection objective, the illuminating light beam focused by the illumination objective in a direction perpendicular to the optical axis of the detection objective in such a way to redirect that the deflected illuminating light bundle forms a light sheet-like illuminating light distribution focused in the focal plane.
- a light sheet microscope is known from DE 10 2011 056 914 A1, in which a light sheet-like illuminating light distribution is focused by an illuminating lens and is deflected by a light deflecting device into a focal plane in a sample that is perpendicular to the optical axis of the illuminating lens.
- a disadvantage of this light sheet microscope is that the light deflection device must lie in the image field of the illumination lens. In the case of two opposite deflection surfaces, both of which must lie in the image field of the illumination field, the size of the sample is therefore limited by the image field of the illumination lens.
- DE 10 2012 109 577 A1 discloses a light sheet microscope with an illumination lens and a detection lens, which are arranged opposite one another. A light sheet-like illumination light distribution is focused by the lighting lens. The illuminating light distribution is deflected into a focal plane by one or more light deflecting devices. The illumination lens and the detection lens can also be offset from one another, so that the light deflection device outside the image field of the illumination lens can be arranged for illumination larger samples with a thinner illumination light distribution.
- this light sheet microscope is mechanically complex and involves high manufacturing costs. Since it requires far-reaching changes to the structure of the microscope, it cannot be retrofitted in existing systems.
- the light sheet microscope according to the invention comprises a detection lens for imaging a target area of a sample, which is located in a focal plane of the detection lens, an illumination lens for focusing an illuminating light bundle into the sample.
- the detection lens and the lighting lens face each other, and the optical axis of the detection lens and the optical axis of the lighting lens are parallel to each other.
- the light sheet microscope further comprises a first light deflecting device with at least a first deflecting surface and a second deflecting surface, each offset from the optical axis of the detection lens are arranged and designed to deflect the illuminating light beam focused by the illuminating lens in a direction perpendicular to the optical axis of the detection lens in such a way that the deflected illuminating light beam forms a light sheet-like illuminating light distribution focused in the focal plane, and a second light deflecting device that is designed to offset the illuminating light bundle focused by the illuminating lens parallel to the optical axis of the illuminating lens and to redirect it to at least one of the two deflecting surfaces of the first light deflecting device.
- a first light deflecting device with at least a first deflecting surface and a second deflecting surface, each offset from the optical axis of the detection lens are arranged and designed to deflect the illuminating light beam focused by the illuminating lens in
- the invention provides that the illuminating light beam focused by the illuminating lens is offset by the second light deflecting device parallel to the optical axis of the illuminating lens. This allows the two deflecting surfaces of the first light deflecting device to be arranged outside the image field of the illumination objective. As a result, it is possible in a mechanically particularly simple manner to illuminate larger samples than in previously known light sheet microscopes. Furthermore, an illumination lens with a larger numerical aperture can also be selected without limiting the size of the sample. As a result, a thinner light sheet can be generated than in previously known light sheet microscopes and thus an improved axial resolution can be achieved. Another advantage of the invention is that the two light deflection devices can easily be retrofitted to existing light microscopes.
- the optical axis of the detection objective is preferably arranged between the first deflecting surface and the second deflecting surface. This allows the sample to be illuminated from opposite directions with the illuminating light distribution. This can be used to increase contrast or to remove shadow artifacts.
- the first deflection surface and / or the second deflection surface of the first light deflection device are arranged outside the image field of the illumination objective.
- the light-sheet microscope comprises a switchable deflection element, which is arranged and formed in the beam path of the illumination objective, the illuminating light bundle focused by the illumination objective in a first setting on the first deflection surface of the first light deflection device and in a second setting on the second Deflecting surface of the first light deflecting device.
- the deflection element can in particular be designed as a tilting mirror or a wobble plate. The direction from which the sample is illuminated can be quickly changed by means of the deflecting element. This is necessary for some light-sheet microscopic methods, in particular methods for increasing contrast or for removing shadow artifacts. This can be used to increase the image quality.
- the second light deflection device comprises a first prism, which is arranged and formed in the beam path of the illumination lens, to deflect the illumination light beam focused by the illumination lens at a right angle to the optical axis of the illumination lens.
- the first prism provides a mechanically simple and inexpensive way of deflecting the illuminating light beam.
- the second Lichtumlenkvor direction comprises a second prism, which is arranged offset to the optical axis of the illuminating lens and designed to deflect the illuminating light beam focused by the illuminating lens in the direction of the first deflecting surface of the first light deflecting device, and comprises the second light deflecting device third prism, which is offset from the optical axis of the lighting lens and is configured to deflect the illuminating light beam focused by the illuminating lens in the direction of the second deflecting surface of the first light deflecting device.
- the two prisms provide an inexpensive way of deflecting the illuminating light bundle in the direction of the first or second deflecting surface of the first light deflecting device.
- the first prism and the second prism are designed to deflect the illuminating light beam focused by the illuminating lens in the direction of the first order deflecting surface or the second deflecting surface of the first light deflecting device parallel to the optical axis of the illuminating lens.
- the deflection of the illuminating light bundle parallel to the optical axis of the illuminating lens is optimal with regard to the smallest possible necessary area of the two deflecting elements and the smallest possible extension of an optical path covered by the illuminating light bundle.
- the illuminating light beam strikes the interface between the air and a medium surrounding the sample perpendicularly. This increases the optical quality of the illuminating light bundle.
- the second Lichtumlenkvor direction comprises a first rhomboid prism, arranged offset to the optical axis of the illumination lens and designed to offset the illumination light bundle focused by the illumination lens parallel to the optical axis of the illumination lens and in the direction of the first deflection surface of the first To deflect the light deflecting device
- the second light deflecting device comprises a second rhomboid prism, which is arranged and configured offset to the optical axis of the lighting objective and to shift the light bundles focused by the lighting lens parallel to the optical axis of the lighting objective and to deflect in the direction of the second deflecting surface of the first light deflecting device .
- the illuminating light beam is through the first or second rhomboid prism both offset parallel to the optical axis of the illumination objective and deflected in the direction of the first deflection surface of the first light deflection device.
- no complex adjustment is necessary in production, ie it is not necessary to align several optical elements with one another in the beam path of the illuminating light bundle.
- Another advantage of this embodiment is that drift, ie a shift of optical elements in the beam path of the illuminating light bundle during operation, cannot result in a deterioration in the optical quality of the light-sheet microscope.
- the light sheet microscope comprises a beam splitter element which is arranged in the beam path of the illumination objective and is designed to split the illumination light bundle as a function of a spectral composition and / or as a function of a polarization.
- the beam splitter element can split the illuminating light bundle in such a way that a first part of the illuminating light bundle is directed onto the first deflecting element with a first spectral composition and / or a first polarization and that a second part of the illuminating light bundle is directed with a second spectral composition and / or a second polarization is directed to the second deflection element.
- An advantage of the splitting as a function of the polarization is that the two light sheet-like illuminating light distributions propagating against one another in the sample and possibly overlapping do not interfere with one another if they have polarization orthogonal to one another.
- the light-sheet microscope comprises a polarization element which is arranged in the beam path of the illumination objective and is designed to set a polarization of the illumination light beam.
- the polarizing element can in particular be used to set the illuminating direction. So in this embodiment in particular by rotating the polarization of the illuminating light bundle, for example by means of a rotatable l / 2 plate in the beam path or an electro-optical modulator, there is a simple possibility of dividing the amount of light from the illuminating light bundle between the first and the second illuminating light bundle.
- the use of a particularly fast switching polarization element, for example a Pockels cell, is particularly advantageous.
- the switching times of Pockels cells are between 5 and 10 kHz. Through the Pockels cell, the direction of illumination can be changed at a particularly high frequency.
- the light sheet microscope comprises an optical element for limiting the effective numerical aperture of the illuminating lens.
- the thickness of the light sheet-like illumination light distribution can be controlled.
- the first light deflection device can be rotated about the optical axis of the detection lens and / or the second light deflection device can be rotated about the optical axis of the illumination lens.
- the second light deflection device is arranged between the illumination objective and the sample.
- the light-sheet microscope is designed as an upright microscope, ie if the illumination lens is arranged below the sample and the detection lens is arranged above the sample.
- the second light deflection device is arranged between the illumination objective and the first light deflection device.
- Both light deflection devices are arranged on the lighting objective.
- the light-sheet microscope is designed as an inverse microscope, ie if the illumination lens is arranged above the sample and the detection lens is arranged below the sample.
