Beam Expander

Beam expanders are lens assemblies that can change the diameter and divergence of a laser beam. Use Galilean telescope (no internal focus) beam expanders to change the diameter of a high power CO2 laser beam for a variety of applications. These beam expanders are available in a variety of different input beam diameter and magnification combinations.

Features:

1. Using imported ZnSe material;
2. Galileo design, good collimation of the emitted light; small light energy loss;
3. Laser beam expansion multiples range from 1.5 to 10 times, with a full range of specifications;
4. Adjustable beam expander can improve the collimation of laser beams with divergence angles up to 19~30 milliradians;
