Leica DMLS - Eyepiece Usage and Care; Eyepiece Handling and Protection

Eyepieces
For direct visual observation. If you are wearing
glasses, pull off the glare protection (5.7), as it
may prevent you seeing the whole field of view.
Only use Leica HC PLAN eyepieces.
Exceptions: Widefield 16x/14 B and 25x/9.5 B
eyepieces, from the range of Leica AG
Heerbrugg/CH, for which a special adapter ring
is required, which is pushed onto the eyepiece
(6.2).
Always make sure the pair of eyepieces have
identical magnifications and field of view
numbers, e. g.
10x/20! Further important
information → p. 23 – 27.
Assembly of graticules*
Only possible for eyepieces with adjustable
eyelens =
M type (5.4).
Attention:
Important: 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/25 and 12.5x/16 eyepieces only:
Screw the retainer ring out of the underneath of
the eyepiece (5.6).
10x/22 and 10x/25 eyepieces only:
Screw out the bottom part of the eyepiece (5.8)
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 and the bottom part of
the eyepiece back in. The eyepiece can be used
both with and without spectacles. When
wearing spectacles, pull off or push back the
anti-glare protection (5.7), as otherwise part of
the field of view may not be visible.
