CRYLIGHT is dedicated to manufacturing high precision beamsplitter cubes. We offer a wide variety of beamsplitter cubes. Our beamsplitter cubes are available in polarizing or non-polarizing models. The polarizing options will split the light of s- and p-polarization states differently, while the non-polarizing cube beamsplitters are designed to split incident light by a specified ratio that is independent of the light's wavelength or polarization state. 
CRYLIGHT owns the top coating expert team and the advanced coating machines in China. Our precision coating centers combine state-of-the-art deposition capabilities to achieve the most wide-ranging and demanding coating designs. If our standard coatings described in this chapter can not meet your requirements, our engineers will help you with a special coating design.
CRYLIGHT offers Polarization Beamsplitter Cube, High Power Polarization Beamsplitter Cube, and Non-Polarization Beamsplitter Cubes.
