Object stage for optical devices

The innovation relates to an object table for optical Ge devices with associated, preferably in two coordinate directions orientable guidance system, one Has guide frame for supporting an object.

From Japanese Notice Publication No. 44-8273 a device for moving an object for microscopes has become known which has a cross-base arrangement includes, which is in communication with a support frame. This device has the disadvantage that in the Holding frame only slides of the same dimensions can be inserted and changing them is time-consuming and is relatively cumbersome.

From the German utility model specification No. 1 623 In addition, an object holder for microscopes is already known, which one after a coordinate direction Orientable & ren U-shaped holding frame includes, in the one Slide can be inserted.

A rapid microscopic serial survey of Objects that are in object containers or on microscope slides different geometry - such as micro test plates, petri dishes, ampoules, test tubes, Cell plates, watch glasses, plane-parallel glass plates, fine-meshed nets and the like - are, however, with These known devices not possible if you raise the additional requirement that the object container or slide against unintentional shifting or shaking relative to the optical axis of the observation device should be optimally secured.

The innovation is therefore based on the task of providing the option for an object table with a train-based guide system for securely holding and quickly exchanging slides or object containers of different types To create shaping.

This object is achieved in that several optional for inclusion in the guide frame of the guide system insertable holding plates of different shapes adapted to the specimen slide or specimen container available.

According to a particularly expedient embodiment of the innovation, the fit between the holding plates and the object carriers or object containers be form-fitting. Finally, at least one fitting piece can also be inserted between Holding plate and specimen slide or specimen container must be available.

The innovation is explained in more detail below with reference to the embodiment shown in the drawing. It shows:

1 shows an illustration of an object table in a top view with a guide system, guide frame and Retaining plate in Eiriraat position;

FIG. 2 shows a section along the line II-II in FIG. 1; FIG.

Fig. 3 shows another holding plate with an associated adapter and object container.

As shown in FIG. 1, on or on the object table ί there is a guide system 2 - k, which consists of the Kreuzachlitt table rails 2, 3 and an additional guide frame k attached to the rail 3. the

Translation devices of the two rails 2, 3 are indicated by double arrows.

A locking lever 5, 5 is located on each of the two sides of the guide frame k. A partially recessed locking ball 6, 6a is fitted into its front part. The lever 5> 5 & is mounted tiltably about an axis 8, 8a and has a spring 9.9a under compressive stress on its rear part (FIG. 2).

Furthermore, a holding plate 10 with a rectangular recess is shown in the observation position. A spring clip 15, which protrudes slightly into the inner recess of the holding plate, serves to hold a specimen container or specimen slide to be inserted, which is not shown in FIG. 1 for the sake of simplicity. The holding plate 10 is pushed into the guide frame k until the two locking balls 6, 6a engage in grooves 7, 7a made on both sides of the holding plate 10a (Fig. 3).

Is a quick exchange of the retaining plate 10, which is in the latched position, for another retaining plate 10a (FIG. 3), this can be done by simply pulling out the first plate and inserting the second plate done. There is no time-consuming determination - for example by means of locking screws and the like - explore borrowed.

In Fig. 3 shows a holding plate 10a, in which Recess a fitting piece 12 can be used of your choice can. The clamping springs 11, 13 projecting into the recesses in turn produce a wobble-free Seat of the PassstUokes 12 and the slide or object exposure container. As object container 1st in Flg. 3 a two

The (η) retaining plate (η) 10, 10a once in the locked position are arranged so as to be secure against wobbling by the described guide means k and locking means 5-9 or 5a-9a.

The recesses of the holding plates 10, 10a - as well as the Means of holding them - are not limited to the embodiments in the Pig. 1 to 3 limited; rather, they can encompass a wide range of variation.
