CO2 Laser Beam Expander, Laser Optics

Laser beam expander is an optical system comprising two or more optical elements and is designed to expand laser beams. CO2 beam expanders are suitable for demanding laser applications including laser materials processing, 3D printing, medical, etc.

SPT CO2 laser beam expander delivers excellent performance for following uses:

• Expand the laser beams and then focus them on a smaller spot.
• Improve the output beam collimation.
• Reduce the laser beam diameter in an acoustic optical modulator or an electrooptical modulator.
• Work with a spatial filter to symmetrize and uniformize the asymmetric spot energy.
