Olympus SZ-III - Optical System

Stage plate
OPTICAL SYSTEM:
The objective, ocular and varifocal lens systems are arranged as shown above.
The beams from the specimen enter the Objective “Ob” at an angle of visual axes
of 12°, wherein they are turned parallel to each other. They further proceed through
the zoom system “ZL, and ZL,” and the fixed lenses “L,”, reaching the Prism
“P,” where they again assume a 12° angle of visual axes and 45° inclination. Then
the beams enter porro-prisms “P,” and finally reach the eyepieces “Oc”. Continuous
zooming variation is performed by vertical displacement of the ZL lenses.
