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, ...

The system described in this protocol does not include a two-photon imaging capability. However, this capability can be easily added by replacing the top periscope mirror with scanning mirrors and by ...

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 ...

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 ...
