Photoeyepieces*
The observation eyepieces HC PLAN (fitting
diameter 30 mm) are designed for direct visual
observation only. Special eyepieces with fitting
diameter of 27 mm
HC . . . PHOTO are used for the adaption of
photomicrographic equipment with a fixed
magnification factor, e.g. DM LD and MPS
systems and for special TV adaption systems
(adapter Fig. 44 – 46!).
Objectives
Always only use Leica objectives of tube length
∞ (infinity)! The standard thread is M25, or for
incident light darkfield objectives BD M32 (Fig.
27). Adapters for objectives with smaller threads
→ Fig. 26. It is customary, though not essential,
to arrange the
magnification increases when the objective
nosepiece is rotated counterclockwise. Lower
the specimen stage as far as possible before
assembling the objectives.
!
Attention:
Close vacant threads in the nosepiece with dust
protection caps (code no. → p. 63).

Lamps, assembly
The lamphousings are secured to the back
of the microscope (1c.6) or to the illuminator
(Fig. 39) with a clamp screw (37.5) and 3 mm
hexagonal screwdriver (2.2). If required, the
intermediate piece* with filter slots (21.6) can be
used, which accommodates filters of 50 mm
diameter.
For 100 W transmitted light, only the LH 107 can
be used!
Before assembling to the microscope, you
should check that the lamphousings have been
properly fitted with 12 V 30 W or 100 W halo-
