Plate beamsplitter
Plate beamsplitters consist of a thin, flat glass plate that has been coated on the first surface of the substrate . Most plate beamsplitters feature an anti-reflection coating on the second surface to remove unwanted Fresnel reflections. Plate beamsplitters are often designed for a 45° AOI. For substrates with a 1.5 index of refraction and a 45° AOI.Plate beamsplitter used in many life sciences, imaging, or laser applications, as well as in the entertainment and design industry.
