Suggestion for fluorescence dark field in the short-wave light with DF-condensor lens 1,2: With actual working time > the
permeability of the ring lens post can leave 1000 hours with HBO lights. The ring lens is as spare part in the offer.
Vorschraubring under the ring lens unscrew, ring out lens take (falls out with careful Aufklopfen of the condensor lens
automatically).
, Vorschraubring replace new ring lens einschrau users.
To the use of the DF-condensor lens 0.12 - 0.85 orients themselves you please in the guidance, which is added to the equipment.

(13) (15) observations with the mechanism for orienting polarization _
The mechanism serves the observation in the polarized by falling light, e.g. with crossed polar one (anisotropy) or from dichroism.
Operation:
Slidegate valves over light outlet (fig. 1/12 and/or fig. 5/49) pull out and by slidegate valves with polarizer for the time being
replace (without compensators
λ
and
λ
/4).
Analyzer slidegate valve up to the first rest into the admission at the Tubusträger push in (fig. 1/5).
Preparation for observation furnish and after Köhler light up.
Analyzer slidegate valves up to the 2nd rest push in.
Polarizer and analyzer on 0 place (0 in relation to point of index). Thus are the polar one crossed.
Preparation take away, field observe, by slight correction of the direction of the polarizer toward maximum darkness in the field
stop, polarizer with wedging screws in this situation determine. Preparation again up put.
Tricks of the table, inserting and rotation of the compensators
λ
and
λ
/4 after the requirements of the investigation of a goal.
For the diagnosis of dichroism without analyzer work (analyzer in first detent).
Quick change between observations with crossed polar ones and in the light field by shifting the analyzer between first and second rest.
(16) Observations with the azimuth screen for inclined Beleuchtung________________________________
Inclined lighting - with the help of an azimuth screen at height of the aperture diaphragm - is a simple procedure phase whether
jekte to make well contrasted visible. The screen is applicable with all objectives of the enlargements from 12,5x to HI100x.
Operation:
Preparation for observation furnish and after Köhler light up (visiting and focusing with difficulty visible objects advantage
detention with complete or to a large extent closed aperture diaphragm. Aperture diaphragm thereafter again open).
Bertrandlinse switch on, aperture diaphragm to the Objektivpu pill center, Bertrandlinse off again switch.
Azimuth screen admission onto the appropriate swallow more amKondensoreinhänger to attack push and with knurling tool
mother (fig. 3/34) wedge.
Field observe. Mobile arm of the azimuth screen first to attack pull out, afterwards sensitivly again push in, until optimal contrast
enters.
Screen with the help of the lever arm azimuthal turn, until optimal contrast enters.
