62-885 50 x 75 mm 50:50 (R:T) N-BK7 Plate Beamsplitter; t=3mm NIR 700-1100nm
The 62-885 is a 50 x 75 mm rectangular beamsplitter, designed with a 50:50 ratio for reflection and transmission. This beamsplitter is part of the Thin BS subtype, featuring a thickness of 3mm, making it ideal for applications that require a compact optical component.
The beamsplitter is crafted from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high homogeneity. This material is particularly suitable for use in the near-infrared (NIR) region, specifically between 700 and 1100nm, making this beamsplitter an excellent choice for applications within this spectral range.
The front surface of the beamsplitter is coated with EDM 47-024, a coating specifically designed to enhance the performance of the beamsplitter within the NIR region. This coating ensures a balanced 50:50 split between reflection and transmission, providing reliable and consistent performance.
The beamsplitter's physical data indicates a reflection of 0.5 and a transmission of 0.5, further confirming its 50:50 split ratio. This beamsplitter is available from Edmund Optics and is currently in stock, as indicated by its weblink status.
