25mm Diameter 70R/30T, VIS λ/10 Plate Beamsplitter

Product Details 30 Arcminute Wedge to Minimize Internal Interference Wide Range of Splitting Ratios Fused Silica Substrate TECHSPEC λ/10 Plate Beamsplitters are designed for use with a 45 degree angle of incidence and random polarization. With a featured 30 arcminute wedge, the effects of internal interference are minimized. Each beamsplitter also includes a multi-layer anti-reflection (AR) coating on the back-surface. TECHSPEC λ/10 Plate Beamsplitters have been optimized for the visible spectrum and are offered in a variety of splitting ratios. These beamsplitters are ideal for laser applications due to the wedged design and high quality Fused Silica substrate.
