Traditionally beam expanders have come as complete, pre-aligned mounted optical systems in an enclosure. While this approach provides a good beam expansion solution for optics up to 200mm diameter, ...

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 ...

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 ...
