Polarising Cube, Medium Power, 450-650nm

Manufacturer's part number :


Manufacturer Altechna


Description :

Polarising cubes for medium power applications optimised for 450-650nm spectral range are AR coated on four input and output working surfaces. Polarising beamsplitter cubes split randomly polarized beams into two orthogonal, linearly polarized components: s polarized light is reflected at a 90° angle while p-polarized light is transmitted.

Each beamsplitter consists of a pair of high precision right angle prisms cemented together with a dielectric coating on the hypotenuse of one of the prisms.
