75 x 75mm 50R/50T, NIR Plate Beamsplitter

Product Details Many Beamsplitting Ratios Available Visible and NIR Coating Options Offered Multi-Layer AR Coated Second Surface C-Mounted Plate Beamsplitters Also Available TECHSPEC Visible and NIR Plate Beamsplitters are ideal for dual magnification imaging systems and for combining low power laser beams. These beamsplitters offer the optimum combination of polished, high-quality optical-grade glass with minimum substrate thickness. The broadband dielectric coatings provide maximum throughput, are ideal for minimizing ghost images, and have much less energy loss than metallic coatings. TECHSPEC Visible and NIR Plate Beamsplitters are coated on their back surfaces with a multi-layer anti-reflection (AR) coating, reducing back reflections to less than 1.0% for each wavelength range. Note that for easy identification, the coated side of the beamsplitter is marked with a black dot.
