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

Ideal for dual magnification imaging systems and for combining low power laser beams, TECHSPEC® Visible and NIR Plate Beamsplitters offer the optimum combination of polished, high quality optical-grade glass with minimum substrate thickness. The broadband dielectric coatings provide maximum throughput, ideal for minimizing ghost images, and have much less energy loss than metallic coatings. Back surfaces are multi-layer anti-reflection (AR) coated, reducing back reflections to less than 1.0% for each wavelength range.
