The 35-947 is a 50 x 75 mm rectangular beamsplitter, designed with a 50:50 ratio for reflectance (R) and transmittance (T) in the visible light spectrum (VIS) range of 400-700nm. This beamsplitter is sourced from the reputable vendor, Edmund Optics, and is currently in stock, as indicated by its weblink status.
This beamsplitter is made of N-BK7, a high-quality borosilicate glass manufactured by Schott. The N-BK7 material is known for its excellent optical properties, making it a popular choice for various optical applications. The beamsplitter has a thickness of 1mm, which is considered a thin lens.
The coating on the front surface of the beamsplitter is EDM 47-021. This coating is specifically designed to optimize the beamsplitter's performance in the visible light spectrum. The beamsplitter's physical data indicates a 0.5 reflection and a 0.5 transmission, which is consistent with its 50:50 R:T ratio.
