2.2.6.2 slit diaphragm
Slit diaphragms are used for microscopic studies of samples with uneingebetteten
small size of the contact surface as well as for the observation of edge regions. The contact surface
has a diameter of 25 mm.
Operation
Diaphragm carrier 2 (2-45/3) in the cross table
50 x 30 mm insert.
One of the three slit diaphragm (2-45/2) in the
Insert diaphragm carrier 2.
NOTE:
For cross table 20 x 20 mm is the
Diaphragm carrier 2 is not required.
Attention
must when working with slit diaphragms
the object-spring plate (2-45/1)
not
be used to a loading
damage to the 0.1 mm thick
Plates for object support to ver-
prevent.
2.2.6.3 Filter for epi-fluorescence excitation
By means of these filters, fluorescent components of the sample and with fluorchromierten
Media saturated voids and defects such as cracks, pores and voids in metal, ceramic,
Plastic and concrete can be made visible. If there is insufficient light intensity of the halogen-
lamp 12 V / 100 W Xe lamp should the additional 150 W (see section 2.2.6.6) is used
be.
The filter set includes:
• 2x excitation filter (short pass filter) KP490, Ø 32
• 1 x excitation filter, blue
B228G, Ø 32
• 1x blocking filter yellow
G247 2E, Ø 32
Installing the filter
Filter turret (2-46/4) after loosening the screw
(2-3/4) out of the illuminator.
Spring ring (2-46/1) from the filter turret corresponding
distant and both excitation filter KP490 (2-46/2)
with intermediate excitation filter B228G
(2-46/3) replace in the filter turret.
NOTE
The sides engraved with the type-
designations of the excitation filter
KP490 must lie against each other.
Blocking filter G247 (2-46/6) in the filter slide
Ø 32 (2-46/5) and insert it into the
Beam path slide.
Fully open the aperture diaphragm (2-18/2) and setting
regulator "lamp voltage" on the control panel LO
12 V control.

NOTE:
Do not touch the filter surfaces as possible, dust with clean hair brush
remove; clean if smeared filter with distilled water and cotton ball.
