68-410 35 x 35 mm 60:40 (R:T) N-BK7 Plate Beamsplitter; t=3mm NIR 700-1100nm

The 68-410 is a 35 x 35 mm rectangular beamsplitter, designed with a 60:40 (R:T) ratio, making it ideal for applications where a higher reflection rate is required. The beamsplitter is constructed from N-BK7 Schott glass, a material known for its excellent optical properties, including high homogeneity and low auto-fluorescence.

The beamsplitter's thickness is 3mm, providing robustness and stability. It is designed to operate within the Near-Infrared (NIR) spectrum, specifically between 700 and 1100nm, making it suitable for a wide range of applications within this spectrum.

The front surface of the beamsplitter is coated with EDM 68-400, a coating that enhances its performance within the specified wavelength range. This coating ensures a high reflection rate of approximately 60% and a transmission rate of approximately 40%.

The beamsplitter's thin lens shape allows for easy integration into optical systems, while its rectangular geometry provides flexibility in system design. This beamsplitter is available from Edmund Optics and is currently in stock, making it a readily available option for your optical needs.
