Coatings
As light passes through an uncoated glass substrate, approximately 4% will be reflected at each surface. This results in a total transmission of only 92% of the incident light. Anti-reflection coatings are especially important if the system contains many transmitting optical elements.
*Low loss V-coatings
*Dual wavelength coatings
*Suitable for high power application
*High reflectance for laser application
*High damage threshold
Broadband over near-UV, VIS to FIR
Insensitive to polarization and incident angle
Low damage threshold, can NOT be used on high power lasers
Polarizing Cube Beamsplitters is cemented by a pair of high precision right angle prisms, the hypotenuse of one prism is coated with polarization dielectric coating, and outsides are coated with AR coating. It split randomly polarized beams into two orthogonal, linearly, polarized components. S-Polarized light is reflected at a 90 degree angle while P-polarized light is transmitted.
