Frequently Asked Questions

PBS cubes are used to split random polarized beams into two orthogonal and linear polarized components.

Each cube is made by assembling two right angle prisms and a dielectric polarizing beamsplitter coating on one of the prisms’ hypotenuse.

Standard PBS cubes are glued cubes for low and medium power applications, while High power PBS cubes are optically bonded cubes for high power lasers.

The laser damage threshold for Standard PBS cubes is >0.3 J/cm2 @ 1064 nm.

PBS cubes have no beam shifts, they provide best performance with monochromatic light source, and the optical paths of transmitted and reflected laser beams are equal.
