Device for optically checking surface quality of metal surfaces, has mirror mounted on a flattened surface of rotation-symmetrical body in aperture in housing, and fixed after adjustment

摘要

The device includes a hand-held housing formed by a laser source (3), a mat plate (9) and at least one flat mirror (14) opposing both such that it reflects the obliquely incident laser beam onto the surface (15) to be checked and forms an image of the resulting scatter pattern on the mat plate. Mirror is mounted on the flattened surface of rotation-symmetrical body (6), shape-locked in an aperture in the housing and fixed after adjustment.
