The non-polarized beam splitting prism is used to make the incident light pass through a certain proportion and be reflected at a certain proportion in the 90° direction. A metal dielectric coating is coated on the beveled edge of one of the prisms. The low polarization correlation of the metal-dielectric hybrid coating ensures that the polarization difference between the S and P polarization states in both the transmission and reflection directions is within 6%. These spectrometers are coated with an anti-reflection (AR) coating to achieve maximum transmittance over the operating wavelength range. UItraopto Precision Optics Co. Ltd. The non-polarized beam splitting prism has excellent spectral flatness over its specified wavelength range, effectively reducing the interference effects caused by incident Angle changes or converging/diverging beams. Through the control of precise polishing, coating and bonding processes, the transmitted and reflected waveforms can be within 1/8λ, with a lower polarization difference and beam offset. Customized products with different reflectance/transmittance ratios and other specifications are accepted.
