Polka dot beam splitter is vacuum deposited aluminium coating with protective dielectric layer on ultraviolet grade fused silica substrate. Coating is deposited in the circularsquare type patterns of preferred dimension and spacing depending on the input beam size. When this beam splitter is placed in the input beam path, it divides the beam energy into equal halves in transmission and reflection. This coating bears the advantage of being insensitive to the angle of incidence and color neutral.
