Abstract
An inclination status monitoring system which optically detects an inclination of a lens as it changes its inclination. A light beam having a diameter greater than the diameter of the lens to be inclined is incident on the lens. The lens has a planar reflective surface surrounding a lens portion thereof. The light beam is reflected on the reflective surface, and the reflected beam is converged by a converging lens and focused on an image receiving system, which enables a user to observe the image formed on an image receiving surface. The image of the reflected beam moves simultaneously as the lens inclination is changed.
