REO offers a range of polarizing beamsplitter cubes that deliver
a combination of good optical performance, high laser damage resistance, and good
environmental stability and durability. In terms of optical specifications, they
deliver a transmitted extinction ratio as high as 10:000:1, while maintaining a
transmitted wavefront distortion as low as λ/20 at 633 nm. The cubes are assembled
using proprietary Activated Covalent Bonding technology, rather than through adhesive
bonding or optical contacting. The elimination of any organics or glues from the
beam path yields a high laser damage threshold and avoids internal optical absorption.
The cubes are typically available in the 1- to 125-mm size range and are fabricated
from either fused silica substrates, for operation in the 266-nm to 2-μm spectral
band, or from silicon, for use at wavelengths from 2 to 5 μm. They are suitable
for use in cryogenic environments, and for industrial, military and spaceborne applications.
