PHOTOMICROGRAPHY

The Olympus PM-6 Small Size Photomicrographic Equipment is

ideal for 35mm photomicrography.

I. For Orthoscope

First of all, the part of the specimen that is to be photographed is brought to the center of

view field. Remove the eyepiece holder from the PM-6 and insert the desired eyepiece into

the eyepiece holder. Re-place the eyepiece holder, with the desired eyepiece in it, to the PM-6,

then mount the PM-6 on the microscope eyepiece tube. After adjusting the cross-line within

the field of view by means of the viewer adjustment ring, the specimen is brought into focus by

urning the fine adjustment handle. More detailed instructions on photomicrography are given

in the PM-6 brochure.

II. For Conoscope

First, produce a conoscopic image by sliding the lower condenser lens out of the optical path

and by inserting a large aperture objective 40X and Bertrand lens according to instructions given

in the section III on conoscopic examination. Next, remove the eyepiece holder from the PM-6

and insert the 10X eyepiece (with helical movement ring) into the eyepiece holder. Mount the

eyepiece holder, with the 10X eyepiece in it, on the microscope eyepiece tube. Gently place (do

not fix) the PM-6 on the eyepiece holder and hold it with one hand. The conoscopic image can

be brought into focus by turning, with the other hand, the helical movement ring of the 10X

eyepiece, while viewing through the viewer. Then screw the PM-6 onto the eyepiece holder,

which in turn is screwed onto the microscope eyepiece tube. For focusing, follow the instructions

given in the preceding section on orthoscopic photomicrography.
