N-BK7 polarizing beamsplitter cube prism
Yutai offers polarizing beamsplitter cubes in 5 mm, 10 mm, 1/2" (12.7 mm), 20 mm, 1" (25.4 mm), and 2" (50.8 mm) sizes.The dielectric beamsplitting coating is applied to the hypotenuse of one of the two prisms that make up the cube. Then, cement is used to bind the two prism halves together (refer to the diagram shown above). The engraved dot on the top of the cube indicates the prism with the beamsplitting coating. Light can be input into any of the polished faces to separate the s- and p-polarizations. Cubes larger than 5 mm also feature engraved arrows indicating one possible orientation.
