GCC-4111 Broadband Beamsplitter Plates
These beamsplitters have moderate absorption but minimal polarization sensitivity. The broad spectral flatness makes them ideal for use with multiple lasers or tunable lasers. Hybrid beamsplitters are less sensitive to changes in angle of incidence. Due to the metallic nature of the hybrid coating, these beamsplitters are not intended for use with high power lasers.
