Coaxial Illuminator; Near-Vertical Illuminator - Leica M-Series User Manual

Illuminators

Coaxial illuminator

• This illuminator is for observing and photographing flat,
highly-reflecting objects such as wafers, integrated circuits
and polished metal sections.
• The coaxial incident light housing fits like an accessory
tube between the optics carrier and the binocular tube,
or between the optics carrier and the phototube (page 33).
• A quarter-wave plate is required when the microscope
carrier AX is used in the vertical position.
Using the clamping screw, secure the quarter-wave plate to
the objective mount.
Using the milled ring, turn the quarter-wave plate until the
required effect is obtained.

Near-vertical illuminator

• The near-vertical (approx. 5°) light beam illuminates
depressions and cavities.
• Shadowing by tools is eliminated.
• This illuminator can only be used with the achromatic
objectives having focal lengths 100mm, 150mm, 175mm and
200mm.
• Spacer rings are required for the Leica MZ7
and MZAPO in order to secure the near-vertical illuminator to
the optics carrier (page 16).
Screw off the objective.
Release the clamping screw and remove the adapter ring
from the incident-light housing for near-vertical light.
For MS5, MZ6:
Screw the adapter ring on to the microscope carrier.

• For the MZ7 and MZ9
5
it is an advantage to attach the
objective to the spacer ring
(page 16). You will then be able
to illuminate the largest field
of view completely.

MZAPO:
First screw the spacer ring(s),
page 16, on to the microscope
carrier, then screw the adapter
ring to the spacer ring.
Release the left or right
clamping screw and change
the cover plate accordingly.
Attach the fibre-optic light guide
on either the left or the right.
To switch on the cold-light
illuminator, refer to the user manual
provided with it.
Turn the rotary knob.
• A movable prism directs the light
from the left or right outlet on to
the object.
