Beamsplitter Cube, Non-Polarizing, 25.4 mm, 1100-1600 nm Broadband

The 10BC17MB.3 Broadband Non-polarizing Hybrid Cube Beamsplitter has moderate absorption but minimal polarization sensitivity. The broad spectral flatness of this beamsplitter makes it ideal for use with multiple lasers or tunable lasers. Incoming beams are both transmitted and reflected 45%, with the s and p-polarized components matched to within 10% of each other. Hybrid beamsplitters are less sensitive to changes in angle of incidence, resulting in an optic that is chromatically neutral for both convergent and divergent beams.

The four faces are antireflection coated with a broadband multilayer dielectric coating to minimize surface reflection losses over the 1100-1600 nm wavelength range, providing R<0.5% per surface. Due to the metallic nature of the hybrid coating, these beamsplitters are not intended for use with higher power lasers.
