2. Darkfield Microscopy

(I) Pull the mirror block changeover lever to the

click stop to put the darkfield mirror block (with

D.F. indication) in the optical path.

I• Confirm that the darkfield mirror block (D.F.) is attached at the left :

►

# ________________________________ _

: side of the mirror block port (when seen from the front).

you pull

1 the optical changeover lever forcibly with the darkfield mirror block :

I set at the right side, it may cause malfunction.

: • Glare may enter the viewfield when rotating the revolving nosepiece I

I or when removing the darkfield mirror block from the optical path

: during darkfield microscopy. Keep your eyes off the binocular

1 eyepieces at such times.

�---------------------------------

(2) If a Nomarski prism, the polarizer, the analyzer, the first order red compensator and

the reticle are in the optical path, remove them from the optical path.

During normal observation, Nomarski prisms SJA, SJ B, SJC or SJE can be left in the optical

path. But remove them when photomicrography is pe,formed or when a sample with much finer

details is observed.

(3) Tum on the power switch of the power supply unit. Rotate its lamp intensity control

dial to CTRL. Set the lamp intensity control dial of the microscope at maximum.

(4) Push the anti-glare ND8 filter insertion/removal lever to put this filter in the optical

path.

(5) Put the NCB 11 filter in the optical path.
(6) Tum the aperture diaphragm dial to fully open this diaphragm.
(7) Push both the OB/PHOTO•SIDE and OB/PHOTO changeover levers to provide the

binocular eyepieces with I 00% light output.

(8) Rotate the coarse focus knob to lower the revolving nosepiece. Rotate the nosepiece

to put the 1 Ox objective in the optical path.
