An energy splitting prism is a cubic structure formed by coating multiple layers of dielectric interference films on one of the prism slopes and bonding them together. The energy splitting prism only considers energy splitting and does not consider polarization state. The incident light requires 45 ° linear polarization, circular polarization, or natural light, with two parallel and perpendicular beams of light. The energy of the emitted light can be customized to different ratios according to requirements. The energy splitting prism has the characteristics of zero absorption, good color neutrality, and high cost-effectiveness, with wavelengths ranging from 250-2500nm, and is widely used in various imaging systems.
