Request InfoOptical Surfaces Ltd.Optical Surfaces Ltd. has announced vacuum-compatible beam expanders for high-power laser applications. The expanders are aspheric mirror-based devices offering either beam expansion or reduction capabilities. Incorporating high precision off-axis mirrors, they provide an unobstructed output and highly efficient transmission and can be used with collimated polychromatic light without the need of any fine focus adjustment. Available in a wide range of fixed or variable magnification configurations, the beam expanders are designed to be easy to use for accurate, unobstructed expansion and...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra September 2023 IssueModular Beam ExpanderOptical Surfaces’ pre-aligned large diameter beam expander modules enable complex 5-degrees of freedom set-up in a matter of minutes.
