Available in versions providing a fixed or zoom expansion factor, a family of laser beam expanders is designed for 355-nm light at up to 100 W (cw). With an 8-mm input aperture and a 22-mm output ...

Optical Surfaces Ltd is a manufacturer of large output beam expander optics enabling interferometers to be used for testing of large optical flats up to 600mm in diameter. Large output beam expander ...

Optical Surfaces Ltd has developed a novel kinematic mounting arrangement for its pre-aligned beam collimator and beam expander sub-assemblies. Traditionally large diameter or longer focal length ...

Accurate high magnification of small aperture laser beams has traditionally been a challenge because the optics associated with such a beam expander are difficult to test using an optical ...
