From this position, i t is easy t o rotate the stage in
45'
increments without having t o
refer to the angular scale, and the stage clicks at the diagonal position, at which position,
the retardation angle is measured. (Take care if you rotate the stage too fast, i t some-
times overrides the click stop position.) T o release the 45' click stops, push back the
45'
click stop lever.
4)
Insert the quarter wave plate or sensitive tint plate into the slot, closest to you at your
right hand side in the intermediate polarizing tube.
To disengage the test plate, you can just pull it back t o its click stop position.

A Berek compensator is optionally available t o measure the birefringence of a specimen.

Conoscopic Observation
1)
Swing in the top lens of the condenser (N.A.
0.9).
and illuminate the specimen with no
need to immerse between the condenser and specimen slide.
2)
Bring the specimen into focus, rotate the Bertrand lens turret ring into the I N position.
3) Focus on the interference figure formed at the back focal plane of the objective from
20X to 100X. (Recommended t o stop down the field irisdiaphragm in case of very small
objects.)
The pinhole cap provided may be used i n place of the eyepiece t o directly view the
interference figure mentioned above. In this case, the Bertrand lens is disengaged.

Photomicrography
1) Photomicrographic equipment
Photomicrography with the Model BHSP requires photomicrographic equipment such
as the photomicrographic system camera, exposure meter, photo eyepiece, etc. Read
the instruction manuals for each equipment.
2)
Photo eyepieces NFK3.3X and NFK5X are recommended for orthoscopic photomicro-
graphy, and NFK2.5X for conoscopic photomicrography.
3) Image magnification is obtained from the equation below:
Objective magnification X N FK photo eyepiece magnification.
