Definitions
- the present invention relates to a microscope system and more particularly to a microscope system comprising an objective lens and an actuator element for moving the objective lens in order to focus the objective lens with respect to a specimen to be examined.
- An optical microscope serves to view a sample by placing it in the central optical axis of an objective lens and by establishing a suitable distance between sample and objective lens, such that an image of the specimen can be formed by the microscope optics, consisting of an objective lens or an objective lens in conjunction with a suitable tube lens. Observation of the resulting image is accomplished either directly by a detector placed in the intermediary image plane or by the eye of the operator, in which case usually an additional optical element (i.e. an ocular lens) is needed.
- an additional optical element i.e. an ocular lens
- Both detector means yield two-dimensional image information, i.e. only one section of a three-dimensional object is "in focus". Given that microscope optics usually exhibit a high numerical aperture, this focused section is very narrow, and in order to construct a three- dimensional image one has to record a series of images at different focus positions. For this purpose the object stage is moved relative to the objective lens, which is fixed in its z- position, or the objective lens is moved relative to the z-position fixed specimen.
- the latter type called "fixed stage” microscopes, have the advantage that assemblies attached to the sample (e.g. micropipettes, perfusion devices etc.) do not need to be moved simultaneously when the focus position is changed.
- Piezo-drives are expensive. To drive n objectives, n piezo drives and n piezo drive electronics boards are required.
- the rotation axis of objective revolvers is usually inclined at an angle in order to allow the changing of an objective without having to withdraw it from its focused position. If the rotation axis were vertical, the objective being rotated out of the beam and the one being rotated into the beam would both touch the holder for the specimen during rotation. However, with motorized drives, which facilitate the re-finding of a previous position, one no longer needs to change objectives without withdrawing them. This allows the usage of schemes for holding objectives, moving them into the central optical axis of the microscope system and focusing them, which serve several other purposes at the same time as will be shown below.
- U.S. Patent application 2002/0001126 Al discloses a microscope system comprising an inventory of a plurality of objective lenses, wherein one of the objective lenses is selected and is moved along a guide rail from a storage position to a reference position within the central optical axis of the microscope system.
- the reference position is defined by a retaining element.
- the guide rail is designed such that the objective lens moves - in the vicinity of the retaining element- substantially coaxially with the optical axis.
- This microscope system has a particularly simple construction for selecting and focusing one objective lens of a plurality of objective lenses.
- the microscope system has a particularly simple and versatile construction for focusing an objective lens.
- the microscope system comprises means for sealing the opening of the support element in order to prevent liquid from passing through the opening, wherein the support element preferably is adapted for liquid-tight sealing of an interior space of the microscope system relative to an exterior space outside of the microscope system.
- the support element in addition to its support and guide function, also may serve as protection for the interior space of the microscope system.
- Still another aspect of the present invention is a microscope system as defined in claim 32.
- the interior space including the objective lens(es) may be completely sealed against an exterior space including the specimen, i.e. against the environment of the specimen, without sacrificing optical properties.
- the protection element may serve as a support for at least one mechanical component, such as an x-y stage or a micropipette, and may comprise at least one integrated electronic connector or at least one media supply channel, thereby serving as an interface between the microscope and the environment of the specimen, which is used to hold, move and/or manipulate the specimen.

- Fig. 7 shows a view like Fig. 5 of a modified embodiment, with a double protection feature serving as mechanical and electronic backbone having been added.
- Figs, la and lb schematically show an example of a microscope system according to the invention.
- the microscope system is an inverted microscope and comprises an objective lens 10, defining a central optical axis 22, a specimen 12 located above the objective lens 10 on a transparent substrate 13, usually made from glass, and a support element 18 forming an outer surface.
- a holding collar 14 is provided, which tightly fits around the objective 10. It can slide within a matching resting ring 16, fitting inside an opening of the support element 18, until, in its lowermost position, it reaches a stable resting state The objective lens 10 and the holding collar 14 penetrate through the opening formed by the resting ring 16.
- the resting ring 16 serves to support the objective lens 10 with the holding collar 14 for a movement coaxial to the central optical axis 22 and relative to the support element 18, thereby pre- centering the objective lens 10 with the opening of the support element 18.
- such sliding engagement between the holding collar 14 and the resting ring 16 is provided by an air gap of, for example, 10 to 50 ⁇ m.
- An actuator element formed by a vertical drive mechanism 20 is provided beneath the objective lens 10 for moving the objective lens 10 along the central optical axis 22 for focusing the objective lens 10 with respect to the specimen 12, i.e. for vertically adjusting the focal plane of the objective lens 10 with respect to the specimen 12.
- the drive mechanism 20 comprises a hole enabling penetration of light through the drive mechanism 20 to and from the objective lens 10 along the central optical axis 22.
- the drive mechanism 20 In a working position shown in Fig. lb, the drive mechanism 20 is engaged with the lower end of the objective lens 10 or its holding collar 14, allowing to move the objective 10 upwards along the central optical axis 22 into a focused position, whereby the drive mechanism 20 also serves to guide the objective lens 18 coaxially to the central optical axis 22.
- the engagement is detachable and is provided, for example, by magnetic means (not shown).
- the holding collar 14 and the resting ring 16 are engaged in such a manner that they provide for a liquid-tight sealing in order to prevent liquids from an exterior space including the specimen 12, i.e. from the space above the support element 18, from passing through the opening formed by the resting ring 16 into an interior space of the microscope system, i.e. the space below the support element 18.
- the air gap between the holding collar 14 and the resting ring 16 is so narrow that the surface tension of the liquids in the exterior space prevents these liquids from passing through this gap.
- the support element 18 has a plate-like design and serves as a protecting lid for providing -together with the liquid-tight sealing engagement of the holding collar 14 and the resting ring 16- for a protection against external liquids in the environment of the specimen 12 even at an extended (focused) position of the objective lens 10.
- the shape of the support element 18 is best chosen such that any fluid spilled takes a predefined route.
- Figs. 2a and 2b show a double protection version of the embodiment shown in Figs, la and lb, which is particularly advantageous when the microscope system is to be used under sterile conditions.
- a protection element 28 is provided above the objective lens 10. It provides a gas- and liquid-tight sealing of an interior space, including the entire microscope with the objective lens 10 and its support mechanism 20, against an exterior space, which includes the specimen 12 and its environment, i.e. the space above the protection element 28.
- the protection element 28 is formed as a protective lid. Its function is to separate the (possibly contaminated) region of the set-up with the specimen from the rest, which includes the microscope and all its mechanical, optical an electronic accessories.
- the protection element comprises an opening 26, over whose inner (lower) end a thin, optically clear diaphragm 24 is stretched and fastened.
- the outer (upper) end of the opening 26 is covered by the substrate 13, which carries the specimen 12 on its outer (upper) side. Protection element 28 and diaphragm 24 together form a liquid- and gas-tight seal, separating the interior of the microscope from the environment of the specimen 12.
- the diaphragm 24 is pressed against the objective 10 when the latter approaches the "focused position".
- a suitable immersion fluid 30 between objective lens 10 and diaphragm 24, the diaphragm 24 forms the outermost optical element of the objective 10.
- an immersion fluid 32 may be kept in a reservoir formed by the opening 26 and the diaphragm 24 in case immersion objectives are to be used.
- the immersion fluid 32 in the reservoir may be replenished from another reservoir in the protecting element 28 (not shown).
- the immersion fluid 32 automatically bridges the gap between the objective 10 (with its extension through the diaphragm 24 and the immersion fluid 30) and the specimen 12 on its support-substrate 13, as is required for the function of an immersion objective, see Fig. 2b.
- Fig. 3 shows a modified embodiment, wherein - in order to allow for optimally sterile conditions - the diaphragm 24 is replaced by a clear window 34, which is connected to the protection element 28 by an elastic collar 36.
- Both the clear window 34 and the elastic collar 36 may be part of a removable protection element 28, which is supported by a fixed body 28 of the miscroscope system.
- the protection element 28 has an opening 26 on top of which the substrate 13 with the specimen 12 is placed and viewed from below.
- the elastic collar 36 surrounds the opening 26 and projects into an aperture of the body 28, with the clear window 34 being provided at the inner (lower) end of the elastic collar 36.
- the removable protection element 28 may be formed by a disposable padding completely surrounding the exterior space with the specimen 12.
- the elastic collar 36 is compressible in the vertical direction.
- the window 34 is pushed upwards and thus a moves in parallel with the objective lens 10 while this is moved through its focusing range, while at the same time a seal is maintained.
- a suitable immersion fluid reservoir (not shown) has to be integrated into the removable protection element 28.
- the material of the window 34 has to be chosen such that it does not deteriorate the optical performance of the microscope system, possibly requiring the usage of objective lenses especially constructed or modified for this task.
- the vertical drive mechanism 20 may comprise a support arm 40, which is moved either by a combination of a coarse drive 42 and a fine drive 44, working in series, or • by a combo-drive mechanism 46, which combines very high resolution with extended travel.
- the coarse drive 42 may be of a motor-driven spindle type, whereas the fine drive 44 may be a piezo stack with proper magnification.
- Combo-drives 46 may comprise alternative piezo motor means, but any other suitable drive mechanism may be employed here.
- Engagement of the support arm 40 with the lower end of the objective lens 10 to be focused may be facilitated by appropriate centering means, e.g. by fitting three spheres 48 fastened at the lower end of the objective lens 10 into a v-groove 50 centered around the central optical axis 22, which is provided at the support arm 40.
- suitable magnets may be employed (not shown).
- the embodiments of the microscope system described so far comprise only a single objective lens 10.
- the invention also relates to microscope systems comprising several exchangeable objective lenses 10.
- several objective lenses 10 are fitted with suitable holding collars 14 and are mounted on a changeover element, such as a rotatable carousel 52 or a linear slider (not shown), which is operable for placing a selected one of the objective lenses 10 into the microscope's central optical axis 22.
- the changeover element is a carousel 52
- the objective lenses 10 are arranged radially around a rotation axis, which is parallel to the central optical axis 22, with the selection being achieved by appropriate rotation of the carousel 52 around the rotation axis.
- the carousel 52 comprises a rotatable support plate 18, having an opening for each objective lens 10.
- Each opening is provided with a resting ring 16 for pre-centering and guiding the respective objective lens 10, which, together with its holding collar 14, penetrates through the resting ring 16.
- Only a single vertical drive mechanism 20 is provided for vertically lifting, i.e. focusing, the selected one of the objective lenses 10.
- the non-selected objective lenses are suspended within the respective ring 16, with the holding collar 14 resting on the resting ring 16.
- Fig. 6 shows a modification of the embodiment of Fig. 3, wherein an elastic collar 56 corresponding to the elastic collar 36 of Fig. 3 is not fixed to the removable padding 28 but is rather directly fixed to the body 38.
- the padding 28 and the body 38 together act as a protection element for liquid-tightly sealing the exterior space with respect to the interior space of the microscope system.
- the (lower) end of the collar 56 facing the interior space does not include a clear window but forms a free end which is adapted to engage with the (upper) end of the objective lens 10 facing the specimen 12 in such a manner as to form a liquid-tight sealing when the objective lens reaches its final (focused) position (in Fig.
- the opening or volume 26 formed by such liquid-tight engagement is preferably filled with an immersion fluid (not shown) pumped into the volume 26 from a reservoir (not shown) located within the body 38 or the padding 28.
- immersion fluid not shown
- Suitable passive ways of immersion fluid change are also conceivable.
- Fig. 6 does not provide the gas-tight protection exhibited by previous embodiments, it facilitates the change of objectives with subsequent application of immersion fluid in an automated, high throughput set-up.
- Fig. 7 shows a modification of the embodiment of Fig. 5, with a double protection feature having been added, which is achieved by a protection element in the form of a plate-like protection lid 28.
- a protection element in the form of a plate-like protection lid 28.
- One opening 54 only is required in the protection lid 28 for the selected objective lens 10.
- the non-selected objective lenses 10 are not exposed and are directly covered by the protection lid 28.
- the protection lid 28 may be constructed similar to the protection lid 28 of Figs. 2a, 2b and 3.
- the opening 54 may create a sealed volume which can hold an immersion fluid by a clear window 34 which is connected to a body 38 via an elastic collar 36.
- the protection lids 18, 28 not only may provide for strict separation of the interior of the microscope from the environment of the specimen 12 (e.g. an environmental chamber, a clean-bench etc.), they may also serve a mechanical "base-plate” for mounting mechanical components above (e.g. an x-y-stage 58, micropipettes, a transmitted light illumination unit) and below (e.g. in Fig. 7 the vertical drive mechanism 40, 42, 44 and a drive 60 for changing the objective lenses).
- a lid of the type shown under 18 this holds only for microscopes without objective changer.
- the compact design shown in Fig. 7 provides for maximal rigidity and, due to the direct mechanical coupling of all critical components, for maximal vibration protection, since all components will vibrate "in phase”.
- the x-y stage 58 may even become integral part of the protection lid 28.
- the specimen substrate or support 13 e.g. a coverslip or a microtiter plate
- the protection lids 18, 28 may also comprises at least one integrated media supply channel for passing a medium, such as a liquid, between the exterior space and the interior space or between one of the interior space and the exterior space and a media reservoir within said protection lid or between different reservoirs within the protection lid.
- a medium such as a liquid
- the protecting lids 18, 28 may also have integrated electronic connectors 64, which connect electronics the interior of the microscope to devices mounted on top of the microscope. This way an electronic backbone is established which is totally sealed and can be kept sterile easily. This is particularly advantageous when the sample itself is to be kept in an environment not favorable for the interior of the microscope and/or when maximal sterility needs to be maintained as in S-2 or S-3 environments.
- the microscope systems shown in the Figures are inverted microscopes. However, the present invention is not limited to inverted microscopes, at least some aspects also apply to upright microscopes.
- the forces in the inverted microscope system provided by gravity have to be generated by appropriate biasing means such as springs. This applies in particular to the suspended support of the objective lens(es), which in an upright microscope would have to be biased upwardly.
