High performance plate beamsplitters are available in 30R/70T, 50R/50T or 70R/30T rations for both the visible(400-700nm) 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 beter meet your application needs. Our low-absorption beamsplitters coatings allow maximum throughput to minimize ghost images and have much less energy loss than metallic coatings. Back surfaces ae multi-layer antireflection coated, which reduces back reflections to less than 1.0% for each wavelength range.

note that these beamsplitters ar designed for a 45 degree angle of incidence (AOI)and random

polarization. typical applications include use in dual magnification imaging systems and in combinin low

power laser beams. curves represent typical results with average polarization values.
