Polarizing Beam Splitters

A line of polarizing beam splitters that are available from stock for overnight delivery for use with engraving, marking and scribing lasers is available from Laser Research Optics.

Laser Research CO₂ laser beam pplitters permit up to 50 percent transmission and ±3 percent of reflectance to facilitate power measurements and beam alignment. Drop-in field replacements for engraving, marking and scribing lasers, they are available from stock with overnight delivery to reduce downtime.

Made in 0.75” and 3” OD sizes from ZnSe with various coatings to achieve their polarization states, Laser Research CO₂ laser beam splitters reflect a specific percentage of the incident energy while transmitting the balance.  A 45 degree AOI and 10.6 microns is typical.
