High performance plate beam splitters are available in 30R/70T, 50R/50T or 70R/30T rations for the broad near infrared (700-1100nm) wavelengths. All offer the optimum combination of polished, high quality optical-grade glass with minimum substrate thickness. The broadband dielectric coating options offer a

choice of spectral ranges to better meet your application needs. Our low-absorption beam splitters coatings allow maximum throughput to minimize ghost images and have

much less energy loss than metallic coatings. Back surfaces are multi-layer antireflection coated, which reduces back reflections to less than 1.0% for each wavelength

range. note that these beam splitters are designed for a 45 degree angle of incidence (AOI)and

random polarization. Typical applications include use in dual magnification imaging systems and in

combining low power laser beams. Curves represent typical results with average polarization values.
