6.4 Objectives
Always only use Leica objectives of tube length
× (infinity)! The standard thread is M25. The
objectives should be arranged so that the
magnification increases when the objective
nosepiece is rotated counterclockwise.
Attention:
Lower the specimen stage as far as possible
before assembling the objectives. Close vacant
threads in the nosepiece with dust protection
caps!
6.5 Light Source for the Transmitted Light Axis
Caution!
Be sure that the lamp housing is discon-
nected from the power supply. Unplug the
power plug and the power supply during as-
sembly.
Caution!
Light sources pose a potential irradiation
risk (glare, UV-radiation, IR-radiation).
Therefore, lamps have to be operated in
closed housings.
