cube beamsplitters

Prismatic or cube beamsplitters are optical elements where the working splitting coating surface works at the incidence angle of incidence 45° being glued inside the glass cube. In such an element there is no shift or deviation in the transmitted beam and the optical paths in transmission and reflection are equal. However, the layer of glue inside the cube is lowers thermal durability of the element. Such elements work in medium and low light power optical systems.
