68-408 25 x 38 mm 60:40 (R:T) N-BK7 Plate Beamsplitter; t=3mm NIR 700-1100nm
The 68-408 25 x 38 mm 60:40 (R:T) N-BK7 Plate Beamsplitter is a high-quality optical component sourced from Edmund Optics. This beamsplitter is designed for use in the near-infrared (NIR) spectrum, specifically between 700 and 1100 nanometers.
The beamsplitter is rectangular in shape, with dimensions of 25 x 38 mm, and has a thickness of 3mm. It is made from N-BK7, a popular optical glass known for its excellent optical properties. This material is identified by the vendor as "n-bk7 schott" in the item data.
The beamsplitter features a coating on the front surface, specifically the EDM 68-400 coating. This coating is designed to enhance the beamsplitter's performance in the NIR spectrum.
In terms of its optical properties, the beamsplitter has a reflection ratio of 60:40 (R:T), meaning it reflects 60% of the incident light and transmits 40%. This ratio is maintained for light incident at normal angles.
The beamsplitter is currently in stock and available for purchase through the Edmund Optics website, as indicated by the "weblink status" in the item data.
