Eyepieces
For direct visual observation: If you are wearing
glasses, pull off or push back the glare
protection (18.7), as it may prevent you seeing
the whole field of view.
Only use Leica
HC PLAN eyepieces.
Exceptions: 16x/14 B and 25x/9.5 B widefield
eyepieces from the range of Leica AG
Heerbrugg/CH, for which a special adapter ring
is required, which is pushed onto the eyepiece
(19.2).
Always make sure the pair of eyepieces have
identical magnifications and field of view
numbers, e.g. 10x/20!

(anti-glare protection 10 mounted or pulled up), 5 PHOTO
eyepiece, 6 10x/ 25 M eyepiece disassembled, 6 Upper part,
7 Lower part, screwed off (applies also for 10x/22 M, 12.5x/
16 M, but not for 10x/20 and 10x/20 M), 8a, b Retainer ring for
eyepiece graticules, can be screwed out, 9 Eyepiece
graticule*, 10 Anti-glare protection, removed for viewers
wearing eyeglasses (it can be pushed back with eyepieces
10x/20 and 10x/22, insertable and remove pos. 8a or 8b). The
12.5 x/16 M model is basically the same as the 10x/25 M
eyepiece.
Assembly of graticules*
Only possible for eyepieces with adjustable
eyelens = M type (18.4). The second eyepiece
should also be an M type.
Attention:
Be extremely careful to avoid dust and
fingermarks, as these will be visible in the field
of view. The graticule diameter is always
26 mm for HC PLAN eyepieces.
10x/ 20 M and 12.5x/16 M eyepiece only: Screw
the retainer ring out of the underneath of the
eyepiece (18.6).
10x/
22 M and 10x/ 25 M eyepiece only: Screw out
the bottom part of the eyepiece (18.8) and screw
out the retainer ring with a blunt blade. Insert
the graticule with the coated side downwards
(in the direction of the objective), so that any
lettering is seen the right way round when later
observed in the viewing direction.
Screw the retainer ring back in.
