(with objectives 25x, 40x and REAR ONE 100x) if the picture of the aperture diaphragm centrically to Bildder ring screens is
not appropriate, for aperture diaphragm with centering screws place behind (fig. 1/9).
Bertrandlinse switch off. In the field appears the picture of the object in the phase contrast, which is improved by connecting the
green of filter.
The instruction in a general manner following the appropriate ring screens are centered to the remaining, in the context of the
microscopic intention intended objectives. The individual ring screens are independently shifted. After unique centring objectives and
ring screen guns can be usually switched without further centring expenditure.
Quick change between phase contrast and quasi - light field is possible:
by full opening of the aperture diaphragm (with objectives 25x, 40x and REAR ONE 100x),
through scolded the ring screen gun on symbol

Operation of the small mechanisms for phase contrast
Objectively and/or phv into the lens turret screw pH in and scolded into working position. Is to be worked alternatively with a
small mechanism DIK D, an empty intermediate ring must between phase objective and lens turret (with white marking;
Intermediate ring is a component of the small DIK mechanism) to be screwed in, in order the off lengthens the objectives to
secure.
Ring screen into the single screen admission insert, objektivwärts pointing inscription of the ring screen; Finger forces away

Preparation present, focus and after Köhler light up favourably focus (with difficulty visible objects with to a large extent
geschlosse ner aperture diaphragm. Afterwards again fully open aperture diaphragm).
Bertrandlinse switch on focus (

Aperture diaphragm so far close, to their edge becomes visible and with centering screws (fig. 1/9) to the phase rings to center.
Bring the picture of the lighting ring with the help of the centering screws at the single screen admission with the picture of the

Operation of the mechanism for differential interference contrast GF-PA _
Intermediate rings of the mechanism DIK D onto the objectives GF-PA of the standard equipment screw; the allocation
intermediate ring objective goes out of the imprinted en größerung out (the intermediate rings DIK D 12.5/25 to function both
with GF-PA 12,5x as well as with GF-PA 25x).
The combinations intermediate ring objective into the objective RH screw in. The objective 12,5x in at the gun with 1 marked eye,
remaining objectives in the number of rising enlargements into the eyes 2, 3, 4… screw in a general manner favourably. This
allocation even with later work with the DIK mechanism maintained, in order adjusting spends to avoid.
