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 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 ...

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 ...

Packaged in a precise opto-mechanical platform, a family of beam expanders has a focusing mechanism that keeps optics from rotating, which helps maintain bore sight accuracy and a minimally aberrated ...

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 ...
