Beamsplitter Cube：
The beamsplitter cube consists of a pair of precision prisms cemented together. The one cemented surface is coated with a multilayer beamsplitter coating. The outside surfaces of the prism are AR coated with broadband coatings to minimize surface reflection losses over the specific wavelength range. |
