5.7.4.3. Collimator sight
The collimator sight is pictured on the Figure 22.
It is purposed for focusing and keyframing with 40, 75, 150, 300mm lenses.
The collimator sight is mounted onto the camera for work with objects at 200-250m from the camera. The sight consists of the
body (153) with two-way mirror (43) on it. There are lenses, prism, and targeting frame inside of the body. The sight is
mounted to the camera by means of the plate (154) with ground glass in it. The bracket can be moved on the lid for an

5.7.4.4. Prismatic sight
The prismatic sight is pictured on the Figure 23.
The prismatic sight (cold zeroing tube) is purposed aiming of the camera axis onto an object. The sight magnification is 3x. It’s
construction allows to turn an eyepiece part in the plane perpendicular to the optical axis of the camera.
Focusing is accomplished by means of the ring (156). Dioptric adjustment is possible by means of the ring (156) in
