Definitions
- the present invention relates to a slider for insertion into a beam path of a light microscope according to the preamble of claim 1.
- a generic slider has a housing for placement in or on the light microscope, a holder which is displaceable in the housing in a displacement direction over a displacement length, an optical element which is aligned from the holder to an optical axis which is perpendicular to the displacement direction, is held, and moving means for moving the holder.
- Such a slide is known from DE 101 12 706 B4.
- a threaded spindle there, which is driven by a motor.
- the spindle is arranged next to the holder, so that it can be moved along the threaded spindle.
- the available space for a slider is limited to a light microscope.
- the shaft may have a width of 19 mm and a height of 3.7 mm.
- the slide from DE 101 12 706 B4 can not be used. Due to the arrangement of the threaded spindle and the motor described there, the width of the slider exceeds the available space.
- a particular objective is also that the slider should have the largest possible passband, that in other words the largest possible portion of the effective width of the slider should be usable by the beam path.
- the slider of the above type according to the invention is further developed in that at least that portion of the moving means, which is located in the displacement direction within the displacement length, in a direction perpendicular to a plane defined by the optical axis and the displacement direction level completely within a cover surface, when moving the holder is covered by this, wherein the cover surface is defined by the optical axis as normal.
- the moving means can be considered to design and arrange the moving means so that the width of the slider at least in its end region, which is in a state inserted into the light microscope at the beam path, substantially only through the housing and the therein - taken holder is determined.
- the width in this end should not be increased by the movement means.
- the width of the slider whose dimension in the direction transverse to the direction of displacement.
- the direction is meant, which also stands transversely to the beam path or to the optical axis of the light microscope at a state of the slider inserted into the beam path of the light microscope.
- the recognition can be considered that in the abovementioned end region, the width of the slider can be kept particularly low, if there are no movement means in this end region next to the holder of the optical element. Therefore, a portion of the moving means, which lies in the direction of displacement within the area which is covered or swept by the holder during the displacement of the holder, does not protrude beyond this area in the transverse direction. Instead, this portion of the moving means is completely within the cover surface, which is covered when moving the holder of this, arranged.
- the invention enables a particularly advantageous embodiment in which the size of an effectively usable extent of an opening of the holder in the direction perpendicular to the displacement direction greater than 48%, in particular between 48% and 68%, preferably between 53% and 63%, and particularly preferably between 56% and 60% of an outer width of the slider is.
- the effective usable extension of the opening of the holder in this direction may be 11mm.
- the opening of the holder is filled by the optical element received therein. In comparison to the prior art, the available space is used much more effectively.
- the available space for a slider or slot at light microscopes is often greater at the end remote from the beam path to the shaft than at the beam path. Accordingly, in the direction of displacement outside the cover surface, a portion of the movement means can in principle also protrude beyond the cover surface.
- the cover surface is to be understood as an area whose normal is parallel to the beam path of the light microscope, ie in the direction of the optical axis, when the slider is positioned on or in the light microscope.
- the movement means can advantageously be the optical element between an extended position, in which the optical element is not in the beam path of the light microscope, and a retracted position, in which the optical element is in the beam path to be moved.
- the housing can thus remain arranged on the light microscope and does not have to be moved in order to move the optical element out of the beam path. This is of particular advantage when an area required to remove the slider from the light microscope is not available.
- the slide is arranged on an objective turret of the light microscope, the size of the area required for removal may depend on the type and position of the objective turret. In particular, with inverse tripods a rotation of the nosepiece may be necessary to remove the slider from the light microscope.
- interference contours which are given for example by the tripod, by attached components such as a holding focus and / or by the lens, restrict the area next to the slide on the light microscope so far that a removal of the slide is not possible.
- the invention offers the advantage that the optical element can be moved out of the beam path via the holder and the movement means, without it being necessary to remove the slider.
- the slider can thus be left in particular in a shaft of the light microscope.
- the holder of the slider is not or hardly moved out of the housing in a process, so that the interference contour is not affected.
- the optical element can in principle be any means for influencing light and in particular have a platelet shape.
- the optical element comprises a prism, in particular a differential interference contrast prism (DIC prism), a ⁇ / 2 or ⁇ / 4 plate, a polarizer, a color filter and / or a diaphragm.
- DIC prism differential interference contrast prism
- a ⁇ / 2 or ⁇ / 4 plate a polarizer
- a color filter and / or a diaphragm Depending on the design of the optical element, different receiving positions or insertion openings for the slide can be provided on the light microscope.
- Particular advantages of the invention in an embodiment of the slide as DIC or C-DIC slider, which is used in addition to a lens of a light microscope, where the available space is particularly limited.
- DIC prism When using a DIC prism, measurements with and without a DIC prism are often required within a series of measurements.
- the DIC prism can be retracted into the beam path via the holder and the moving means and also removed therefrom. Interrupting the series of measurements for modifications to the microscope is therefore not necessary.
- the slide according to the invention can be advantageously used.
- One possible embodiment of the slider according to the invention provides a diaphragm, so that the slider can be used, for example, as a field diaphragm or aperture diaphragm.
- the holder of the optical element can be embodied, for example, as a frame which completely surrounds the optical element on its circumference.
- the frame may also be U-shaped and be open at the side which, in the case of an extended position of the frame, in which the optical element is not in the beam path, points towards the beam path.

If a spindle is present, then it runs with its longitudinal axis toward the housing opening, but preferably ends before it. In a retracted position in the optical path of the optical element, the holder is thus held only with an end portion of its internal thread on the spindle.
- the dimensions of the housing opening can in particular correspond to the cross section of the beam path at the pickup position for the slider on or in the light microscope.
- a basic idea of the invention may be formulated such that at least a portion of the moving means lying in the displacement direction within the displacement length is completely within the dimension of the housing opening in the direction transverse to the displacement direction.
- the spindle may be provided a coupling point for a key, such as a hexagon socket, in which an Allen key can engage.

Because of the limited space, it is preferred that the motor is arranged in the displacement direction outside the displacement length. Depending on the light microscope, the width of the slider outside the displacement length may be greater. It can be provided that the motor is arranged with its axis of rotation at an angle to the direction of displacement. As a result, the total length of the slider, so its dimension in the direction of displacement, kept low.

- the slider 100 has a housing 10, a holder 40, an optical element 50 held by the holder 40, and moving means 30 for moving the holder 40 within the housing 10.
- the holder 40 With the movement means 30, the holder 40 can be moved along a displacement direction 5. In this way, the holder 40 between the position shown in Fig. 1, in which the optical element 50 is located in the beam path of the light microscope, and an extended position in which the holder 40 and the optical element 50 are located outside the beam path can be moved ,
- FIG. 2 A situation where the holder 40 and the optical element 50 are in the extended position is shown in FIG. 2 for a second embodiment of the slider according to the invention. Entered there is also the displacement length 7, via which the holder 40 is moved from the retracted position to the extended position.
- the displacement length 7 can, as shown in FIG. 2, be determined as a displacement path 8 of that outer edge of the holder 40, which points in the position moved out of the beam path to the beam path of the light microscope, plus the extension of the holder 40 in the displacement direction 5.
- the range available for the removal of the slider 100 may be severely limited.
- this free area is limited by the interference contour 110, which may be given by a part of a tripod of the light microscope, for example. Because of the interference contour 110, therefore, the slide 100 can not be removed from the beam path of the light microscope in the illustrated case.
- moving means 30 are provided according to the invention. By this, the holder 40 and the optical element 50 can be moved into and out of the beam path without requiring movement of the housing 10 of the slider 100.
- the housing 10 has a housing opening 12, so that the beam path of the light microscope is not affected by the housing 10 when the holder 40 is extended.
- the moving means 30 comprises a spindle 31 which extends in the displacement direction 5.
- the holder 40 At one of the housing opening 12 remote from the end of the spindle 31, this is mounted on the housing 10. At the opposite end of the spindle 31, the holder 40 is arranged, which has a nut 41 for coupling to the spindle 31.
- a guide track for the holder 40 is provided in the displacement direction 5, so that a rotation of the spindle 31 leads to a movement of the holder 40 in the displacement direction 5.
- the available space for the slide 100 on the light microscope space is usually severely limited.
- the width of a slider may typically be only about 2 cm or less.
- a height of the slide, in Fig. 1 thus out of the plane, may be in many cases even only a maximum of 4 mm.
- a special arrangement of the movement means 30 is provided according to the invention.
- the movement means 30 should not protrude out of the region in the transverse direction 6, which is covered by the latter when the holder 40 is displaced.
- the movement means 30 are located within the area covered by the latter when the holder 40 is displaced. che.
- the space requirement of the slider 100 in the transverse direction 6 can thus be kept particularly low. In this case, the space in the direction of displacement 5 is used particularly efficiently.
- the moving means 30 can also extend or expand further in the transverse direction 6.
- the compact arrangement according to the invention causes the spindle 31 to extend towards the housing opening 12, ie in the direction of the beam path of the light microscope.
- the spindle 31 does not protrude into the beam path, this ends before the housing opening 12. If the holder 40 retracted into the beam path, it is therefore held only at its outer edge of the spindle 31.
- this has a coupling point 51.
- a hexagon socket may be provided as a coupling point 51, so that the spindle 31 can be rotated with an Allen key (not shown).
- the Allen key can also be retracted by a motor.
- a round head hexagon which is resiliently mounted, can be used.

- the holder 40 may have a flag 47, which covers the position sensor 90 during extension of the holder 40 and thus triggers a detection signal.
- electronic control means (not shown) connected to the position sensor 90 are arranged to perform a reference run. This is used to determine how many steps or revolutions of the motor are necessary to move the holder 40 between the retracted and the extended position. Particularly accurate results can be obtained with a second Position sensor (not shown) can be achieved, which is arranged to detect a retracted into the beam path position of the holder 40.
- the holder 40 under certain circumstances conceals a part of the beam path when it has moved into the beam path. As can be seen from FIGS. 1 and 2, this hidden area is largely determined by the size of the internal thread 41 of the holder 40. Therefore, it is desirable to provide the smallest possible diameter for the internal thread 41 and consequently also for the spindle 31. Such a long spindle 31 with a small diameter can be made difficult without impact error, whereby the spindle 31 may run restless. Thus, the slider 100 is not crazy in a troubled run the spindle 31 on the light microscope, holding means are preferably provided.

- the spindle 31 is held by a spindle bearing shell 11.
- the spindle bearing shell 11 and a region of the spindle 31 adjoining it are designed to be magnetic.
- the spindle 31 can thus be pulled out of the spindle bearing shell 31, whereby the holder 40 can be pulled out of the beam path of the light microscope.
- such a long rotation of the spindle 31 is unnecessary. Pulling out the spin del 31 is only possible if this is not prevented by an interference contour 110. If the slide 100 is introduced into an insertion opening next to an objective of the light microscope, then the interference contour 110 can depend on the rotational position of the objective revolver. Depending on the rotational position thus pulling out the spindle 31 may be possible.
- the slider 100 shown in Fig. 2 can be made cheaper than the slider 100 of FIG. 1. Because of the possibility of manual adjustment of the slider 100 of FIG. 2 is preferably used in upright microscope stands. Inverse microscopes, however, the accessibility to the handle may be limited.
- the accessibility can also be limited by a sample support table.

- the driver 36 and the lever 37 protrude beyond the interference contour 110. Consequently, with them a displacement of the extension rod 48 and the holder 40 can be carried out only in certain rotational positions of the nosepiece, in which no interference contour 110 as shown in Fig. 11 is present.
- the advantages of the invention can be achieved, in particular that a displacement of the holder 40 held by the optical element 50 between a retracted into the beam path of the light microscope and a position extended from the beam path position is possible without the housing 10 of the Light microscope must be removed.
- the slider 100 according to the invention also has a very small width, ie a very small extent in a direction transverse to the direction of displacement, whereby the slide 100 according to the invention can be used even with very limited available space.
- a motorized movement of the optical element 50 is made possible.
- a comfortable adjustment of the optical element 50 can also take place when the slider 100 is not accessible to a user. This may in particular be the case when the light microscope is in an incubation chamber. But even with the accessibility of the slider 100 for a user can be increased by a motorized control ease of use.
