A two-position instrument that uses a fixed-size image and doubled, adjustable object size to determine the radius of curvature of the reflecting surface

The instrument uses two self-luminous sights (object), the first in the form of a red field and the second in the form of a scaled green pattern, which are represented on a graduated arc track to maintain a constant distance from the eye

The sights can move along the arc, zooming in and out thanks to a mechanical system controlled by a special knob

Two color filters

Movable base

Graduation from 0-180 degrees

No power supply included
