1. Brief introduction
Wedge Prisms provide a low coefficient of thermal expansion and high transmittance from the UV to the NIR. The wedge prism is a substrate with a certain angle that is not parallel. Both sides are precisely polished, it is mainly used for beam splitter or as windows substrate. The wedge angle can be used to eliminate the influence of the reflected light (ghosting) on the opposite side, which is used for sensitive occasion of light.
