Most UV lasers have a small light spot (0.7-1.2mm). UV beam expanders can expand the light beam to the spot size required by the back-end optical path and optimize the beam quality.
1. Complete product series, all beam expanders have divergence angle adjustment function, and there are also continuously variable magnification beam expanders for high-precision applications.
2. It adopts a compact and stable lens structure design, which has extremely high pointing stability and the ability to shrink and expand the beam.
3. All beam expanders are made of quartz, using ultra-low absorption coating technology, and the single lens transmittance T>99.8%.
