Applications : All kinds of optical instruments or optical applications biotechnology equipment medical and energy industries, are available upon request to equipment , medical and energy industries, are available upon request to achieve the purpose of the optical effect. Based on different spectral characteristics, it could be two kinds : Neutral and Color bean splitter. Neutral splitter is about a bunch of the same spectral composition of the two dynasty; color splitters includes reflection and transmission. Besides , according to the polarization of light, the light beam is divided into S polarization and P polarization, which is called the Polarization splitters.
