Movie objective (20) constructs the image of object in to personnel the window of film
gate. Through the light beam by obturator (9) image of the over- bear by its mirror
surface to the flat lusterless the surface (21). With the aid of the double-lens objective 22,
two roof-shaped prisms 23 and 24, three-lens objective (25) mirror (26) image with the
lusterless the association is transferred into front focal plos - the bone of eyepiece (27).
Objectives (22) and (25) are established thus that between them it is formed parallel
course of ray, which makes possible by the displacement of the ocular part of the
magnifier in the direction of the ocular basis of observer to change the position of the exit
pupil of magnifier for the observation with right and left eye.
