Target mark projector for laser aiming and measuring - has graticules reflecting laser beam but passing visible light and optical element to adjust projector optical axis

摘要

A target mark projector for laser aiming and measuring projects a mark and tests and corrects the direction and functioning of the laser sender and receiver. The target mark collimator (10) has graticules (11, 11a) with mirror surfaces (12) reflecting the laser beam, but passing visible light. An optical element (13) in the light path adjusts the projector (10) optical axis (14) w.r.t. the optical axes (15) of the laser sender and receiver (17, 17a).
