Beam Expanders

Beam Expanders

Features

  • 350nm to 1600nm
  • Designed for diode lasers
  • Coated for diode wavelengths
  • 3X, 4X, 8X

 

Many of the beam expanders in the market are coated for YAG or doubled YAG. They also have very small input apertures. Since diode laser come in very many many wavelengths, we needed beam expanders to match the wavelengths of diode lasers. Therefore we designed a series of beam expanders to cover all the diode wavelengths from 350nm to 1550nm.

They have a large input aperture and expansions of ~3X, 4X and 8X. Beam sizes from 2mm to 45mm can be generated. These beam expanders have very well corrected optics with low wavefront error.

These beam expanders can be integrated with the lasers and tested as a complete system.
