Lattice change device for optical grating that is utilized for wavelength adjustment of dye laser, has lattice holders comprising lattice platform that is adjustable in two degrees of freedom relative to positioning member

摘要

The device has a positioning member (11) e.g. turntable and carriage, fastened at a base body (10), where two lattice holders (14) are secured at the positioning member. The lattice holders are moved into a work position by movement of the positioning member relative to the base body and comprise a lower lattice platform (15) that is adjustable in two degrees of freedom relative to the positioning member. A threaded spindle (13) is rotatably supported at base body parallel to a displacement direction (12), where the base body comprises a u-shaped profile.
