45-855 50 x 50 mm 50:50 (R:T) N-BK7 Plate Beamsplitter; t=3mm NIR 700-1100nm
The 45-855 is a 50 x 50 mm rectangular beamsplitter, designed with a 50:50 (R:T) ratio, meaning it reflects and transmits 50% of the incident light, respectively. This beamsplitter is made from N-BK7, a high-quality borosilicate glass known for its excellent optical properties, including low autofluorescence and high damage threshold. The glass has a thickness of 3mm, providing robustness and stability.
This beamsplitter is specifically designed for the Near-Infrared (NIR) spectrum, with a wavelength range of 700-1100nm, making it ideal for applications such as optical telecommunications, biomedical imaging, and night vision technology. The coating on the front surface is EDM 47-024, which contributes to its high performance within its specified wavelength range.
The beamsplitter's thin lens shape allows for easy integration into various optical systems. The physical data indicates a 0.5 reflection and 0.5 transmission rate, ensuring balanced light distribution. This beamsplitter is available from Edmund Optics, a leading vendor in the optical industry, and is currently in stock, indicating its popularity and reliability.
