device for the parallel and casting a laser beam by adjusting strahlablenker manipulierbaren

摘要

The devices or components are adjusted so that the laser beam coincides with their optical axis, or vice-versa. The adjustment device consists of a mirror placed in the beam path, with a grating centred on the optical axis and diffracting the light. The mirror is in the form of a plate exactly perpendicular to the optical axis, on whose side facing the laser beam the reflecting layer is applied, covering only the lines of the grating and leaving free the rest of the plate.
