Variable Beam Expanders

VEX series Variable manual Laser beam Expanders are used to increase or decrease laser beam diameter. Standard or custom-made laser beam expanders for the UV, visible, and NIR spectral ranges feature a unique mechanical sliding-lens design, ensuring high pointing stability and minimal dimensions.

These variable magnification (zoom) beam expanders are designed for the required wavelength and each type of our beam expanders have divergence adjustability.

Lens material	UVFS

LIDT	3 J/cm2 (10 ns @ 355nm) 5 J/cm2 (10 ns @ 532 nm) 10 J/cm2 (10 ns @ 1064 nm)

Description

Details

Optical elements of laser beam expanders are made of fused silica with high LIDT coatings and provide stable and reliable performance even when using them with high power lasers. Large input and output apertures allow the optical beam expanders to produce diffraction-limited expanded (or reduced) beams for a wide range of input beams.
