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.

Ultraopto’s Non-polarized Beam Splitting Prism is a high-performance optical component expertly engineered for balanced light beam splitting with minimal polarization dependence, serving as a core part in laser systems, fiber optical communication, precision optical imaging and interferometry setups. Crafted from premium N-BK7 optical glass and high-purity fused silica, our non-polarized beam splitter prism is composed of two precision right-angle prisms cemented together with a high-quality metallic-dielectric coating on the hypotenuse, ensuring the transmission (T) and reflection (R) of S and P polarization states differ by less than 5% and maintaining the original polarization state of the incident beam without distortion. This optimized coating design delivers a stable and customizable split ratio (50:50, 70:30, 80:20 and more) with high accuracy, meeting the diverse light splitting requirements of different optical systems while minimizing light absorption and loss for maximum energy utilization.
Manufactured with ultra-precise grinding and polishing processes, our non-polarized beam splitter prism implements strict micron-level dimensional tolerance control and angular precision, with a surface flatness of λ/4 @632.8nm and a superior surface quality rating of 40-20 scratch and dig. The input and output faces are coated with anti-reflection (AR) coatings tailored to specific wavelength ranges (400-700nm, 700-1100nm, 1100-1600nm and custom ranges), reducing average reflectivity to less than 0.5% and further enhancing optical transmittance efficiency. The prism features excellent beam deviation control (less than 3 arc minutes) and a clear aperture of over 85%, ensuring stable and high-fidelity light beam transmission and splitting, and avoiding light path offset or signal distortion in precision optical systems.
With a robust and compact structural design, our non-polarized beam splitter prism exhibits exceptional environmental adaptability, resistant to temperature changes, mechanical vibration and industrial field wear, and can operate stably in both indoor laboratory conditions and harsh industrial working environments.
Ultraopto’s high-precision Non-polarized Beam Splitting Prisms are widely applied in a broad range of professional optical fields that demand balanced and polarization-independent light splitting, including laser systems for laser processing, laser alignment and laser measurement, where they realize stable beam splitting without altering the laser’s polarization state and ensure the accuracy of laser operation. They are also core components in fiber optical communication systems (40G/100G components included), providing reliable light splitting for high-speed signal transmission and optical network construction, and in precision optical imaging systems such as industrial machine vision, biomedical imaging and professional photography, delivering clear and undistorted image transmission for high-resolution detection and observation. Additionally, these prisms are essential in optical interferometry and spectral analysis equipment for scientific research, laboratory optical experiment platforms and optical metrology instruments, meeting the high-precision light control requirements of modern optical technology and scientific research.
