E vounting the Camera Unit (Fig, 29)
1. Loosen the clamping screw @ of the NFK photo eyepiece adapter
{PMAADF) ©.
2, Attach the NFK photo eyepiece adapter (PM-ADF) © to the trinocular

‘camera back, a shutter speed at 1/2 second or slower is rec-
‘ommended so as to reduce the mirror-lockup shock.
€ Focus Adjustment
The focus of the eyepieces and the camera film plane are not the
‘same. Consequently, always perform camera focusing by using the
focusing telescope of the camera unit. For details, referto the instruc-
tion manual of the photomicrographic system.

© When using daylight type film in the camera,
+ The blue filter is solely designed for visual observation (day-
light) If this filter is engaged while taking photographs with
daylight film, the color reproduction will be poor.
1. Mount the light balancing fiter (45LBD-2N) @ in the filter holder @
of the microscope frame,
2. Turn the light intensity knob G). To obtain illumination close to day-
light, set the index of the knob at 5 in case of the CH30, and 4 in the
case of CHAO,
