Product Family Description

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.
