High Power Beam Expanders
Special Optics High Power beam expanders are specifically designed with a convex first surface, which diverges the return reflection from the first lens surface and prevents any damage backstream of the beam expander.
Note: Low Power beam expanders may have a return reflection that is not suitable with high power lasers.

- Large Input Apertures
- High Transmission
- No Focused Retro-reflections
SPECS
- Coating Damage Threshold500 MW/cm2
- Transmission> 97%
- Useable Spectral Range248- 1550 nm
- Wavefront Distortion< 1/4 Wave
