Mounting the OM camera back
1)
Mount the photo ey piece adapter P,'v1·ADF
C1;
(into which a choice of
NFK photo eyepiece is inserted), Photomicro adapter {MOM-U
~2~
and
OM camera back '3; on the photo tube in t his order. (F ig. 28)
2) The compatible photo eyepieces are NFK3.3X and NFK5X.
3) Bring the specimen into focus. looking through the viewfinder of Ihe
camera.
4) Photomicrographic magnification equals the objective magnification
multiplied by the photo eyepiece magnification.
*
To take a good photomicrograph with a single lens reflex camera back, a shutter speed at 1/2 second or
slower is recommended so as to reduce the mirror·lockup shock.
Use of the light balancing filter 45 LBD-2N
(optionally available)
1)
Remove the blue filter from the condenser.
2) Slip a 45LBD-2N filter into the filter mount
CG
at the light exit on the
microscope base. (F ig. 29}
3) Turn the voltage control dial
(2)
until the dial is aligned at the gradua·
tion "10" (maximum), and daylight color can be obtained. {For CHS
only)
*
The 45LBD-2N filter cannot be used with the CHT microscope for
color temperature regulation.

Use of the
b~ue
filter 32.5C-2
1)
Engage the blue filter as used for observation in the condenser.
2)
To obtain color temperature for daylight type film, set the voltage
control dial
(~)
at the graduation
"9"
for CHS. or at the graduation
"10" for CHT.
*
If a photograph tends to overexposure, do not change the voltage control dial, but apply an optional N.D.
filter (45mm dia.) to the filter mount at the light exit on the microscope base.
*
Since the blue filter tends to characteristically leave somewhat a yellowish tint, an optionally available
45 LBD-2N is recommended for better improvement of color rendition in conjunction with the CHS micro-
scope. However, the CHT microscope can be used only with the blue filter for color temperature com-
pensation.
