Terahertz Beam Expander Reflection | SIMTRUM Photonics Store

Reflective beam expanders are suitable for applications requiring broadband or achromatic beam expansion and a variety of different light sources.

This series of beam expanders is designed with total reflection to work with a variety of lasers, including tunable, UV, and ultrafast sources. Its innovative design ensures high precision with minimal wavefront distortion. Various integrated design elements, including reflective flats, threaded and through holes, help simplify alignment and installation and can be integrated into any laser application. The monolithic design ensures performance and stability and is not affected by temperature changes.

The reflective beam expander provides 5x multiple magnifications and fits in a variety of coating options for the UV, visible, and IR spectrum.
