Device for scattered light measurement for inspection of upper surfaces of objects to measure hollow profiles, has measurement surface inclined to line so that plane, main plane and plane derived from catacaustic are cut into straight lines

摘要

The device has a measuring device comprising a measurement surface with a lens. A catacaustic-side combustion point (A) of the lens is in coincidence with another combustion point (B) of a hollow mirror (2). The measurement surface is inclined to a connection line of a combustion point so that a plane stretched by the measurement surface, a main plane of the lens and a plane derived from a catacaustic (1) of the hollow mirror are cut into straight lines. The catacaustic of the hollow mirror is formed on the measurement surface under a deflection mirror.
