68-412 50 x 50 mm 60:40 (R:T) N-BK7 Plate Beamsplitter; t=3mm NIR 700-1100nm
The 68-412 is a 50 x 50 mm rectangular beamsplitter, designed with a 60:40 (R:T) ratio, meaning it reflects 60% and transmits 40% of the incident light. This beamsplitter is made from N-BK7 glass, a popular material in the optical industry due to its excellent optical properties and high damage threshold. The glass has a thickness of 3mm, providing durability and stability.
This beamsplitter is specifically designed for the Near-Infrared (NIR) region, with a wavelength range of 700-1100nm, making it ideal for applications such as optical telecommunications, bio-imaging, and spectroscopy. The front surface of the beamsplitter is coated with EDM 68-400, a coating that enhances its performance in the specified wavelength range.
The beamsplitter's thin lens shape allows for easy integration into optical systems, while its rectangular geometry provides flexibility in system design. The beamsplitter's physical data indicates a reflection of 0.6 and a transmission of 0.4, aligning with its 60:40 (R:T) ratio.
This beamsplitter is available from Edmund Optics and is currently in stock, according to the vendor's website. For more information, users can refer to the provided weblink.
