12. Photomask

The photomask of the pattern shown in the figure is put into the optical path by

turning down the reticle in/out lever on the front panel of the microscope.

This

photomask is used for trimming and focusing in photomicrography, and diopter

adjustment of the eyepieces.

Rectangular frame: The rectangular frame shows the photomicrography range of a

35mm SLR camera.

It also shows the photomicrography range

of a photomicrographic attachment used with the 2.5 x PL lens.

(If a PL lens of different magnification is used, determine the

photomicrography range by looking through the finder of the

photomicrographic attachment.)

Double crosshairs: The double crosshairs are used for diopter adjustment of the

eyepieces and centering of the condensers.
