Profile view, showing the subject engaged in a test. Details of the prism unit are visible here, including opposing planoconvex/planoconcave lenses, custom lens mount, forked yoke, translation stage, and the top of the stepper motor.
|
A somewhat bemused subject gazes at the target, conscious of being watched. From this side of the lens unit, more of the pivoting yoke is visible, as well as the flexible coupler between stage and motor. PC whirs idly in the background.
