Positioning the eyepieces
The eyepieces are positioned into the eyepiece
connection pieces.
For the DM ILB and DM ILT tubes, use only the
following eyepieces:
10x/18 Br (M),
10x/20 Br (M) or
15x/14 Br
When using a tube from the DM L range, use the
corresponding eyepieces:
HC PLAN 10x/20 (M)
HC PLAN 12.5x/16 M
Widefield 16x/14 Br (M)
+)
Widefield 25x/9.5 Br (M)
+)
+)
also requires a spacer ring
Br) eyepiece for wearer of spectacles
For information on diameter, visible object sur-
face and overall magnification of the microscope,
refer to chapter “Specifications; Performance
data“.
Positioning the graticules*
Graticules can only be retrofitted by the user for
the abovementioned HC PLAN eyepieces. For
the abovementioned eyepieces for the DM ILB
and DM ILT, the graticules need to be retrofitted
at the factory.
Basically, graticules may only be used for eye-
pieces with adjustable eyelens = Type
M.
Important:
Be extremely careful to avoid dust and
fingermarks, since this will be visible in the field
of view.
The graticule diameter is always 26 mm for HC
PLAN eyepieces and 19 mm for the standard
eyepieces for the DM ILB and DM ILT tubes.
Eyepieces 10x/18 M only:
• Unscrew the sleeve from the lower part of the
eyepiece.
• Insert the graticule with the coated side
pointing downwards (in the direction of the
objective) so that any lettering appears the
right way round when observed in the viewing
direction later.
• Screw the sleeve back in.
Eyepieces HC PLAN 10x/20 M and HC PLAN
12.5x/16 M only:
• Unscrew the retainer sleeve from the lower
part of the eyepiece.
• Insert the graticule with the coated side
pointing downwards (in the direction of the
objective) so that any lettering appears the
right way round when observed in the viewing
direction later.
• Screw the retainer sleeve back in.
Positioning the photo eyepieces*
The HC PLAN viewing eyepieces are designed
for direct visual observation. Special eyepieces
with an insertion diameter of 27 mm and the
engraved identification HC...PHOTO are used
for adapting micro-photographic equipment
with fixed magnification, e. g. DM LD and MPS
systems, as well as for special TV adaptation
systems (use the proper adapter!).
Additional information on the adaptation of
photo and video equipment → separate instruc-
tions.
