Optical Surfaces Ltd. announce a new series of Reflective Beam Expanders with an output clear aperture of 75mm and a selection of magnifications, which are designed for researchers requiring high ...

LASER COMPONENTS offers a range of beam expanders for YAG systems and other wavelengths, used primarily for increasing laser power densities at the focal point, and beam guidance over long distances.

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 ...

Flat optics based on patterned liquid crystals (LCs) has recently received extensive research interest. Comparing with dielectric metasurfaces which are usually fabricated by sophisticated lithography ...
