direction. To the shift in against of set direction keys against-intimately and guns with the hand turn in the Kontrasttubus push in). The
cover is correct then for all 3 ring modulators, which is equipment for positive and negative phase contrast and central dark field

(2) the
filter change-over switch
The Filteraufnahmen in filter change-over switch (fig. 1/16) can be equipped after the requirements also freely selected filters. The
photographs in the filter change-over switch 5x are furnished to one for filter thick up to 4 mm, in the filter change-over switch 10x are
intended the gun for the admission of filters or filter combinations (Fluoreszenzmikroskopie) up to 10 mm of thickness.
The equipment of the filter change-over switch with filters:
Clamping screw (fig. 1/17) with box spanner loosen, filter change-over switch upward fold up and dig
Circlip of the Filteraufnahme take out, filter in set or exchange, to good seat (perpendicular to the passage of light) pay
attention, circlip replace.
Proposal for filter placing of the standard equipments (on this placing the available operating on line purchase takes):
Filter D 281 (neutralgrey) into the admission, those that
Marking 1 faces
Filter C 312 (conversion filters blue) into the admission,
those the marking 2 faces
Filter V 231 (green) into the admission, those the marking 3
faces
The admission opposite the marking 0 remains as freer
Passage empty.

necessary requirements of the preparations
- Slide formats: The object owners at the JENAVAL tables are 26 mm co-ordinated with object carrier of the format 76 mm x. Tighten
right object owner part after loosening of the clamping screw into suitable position schie ben and screw with en idiom of shorter slides
again.
- Slide thickness: The slide thickness is not 1.5 mm if possible over cry ten, if accurately after Köhler is to be lit up (loss at lighting
aperture!).
- Use of coverglass: The objectives of the standard equipments with apertures >0,25 are counted for the observation of preparations on
coverglass (excluded all rear objectives for homogeneous immersion). Marking e.g.: GF-PA 40x/0,65
