47-026 25 x 38 mm 50:50 (R:T) N-BK7 Plate Beamsplitter; t=3mm NIR 700-1100nm
The 47-026 25 x 38 mm 50:50 (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 3 mm. It is made from N-BK7, a type of borosilicate glass known for its excellent optical properties, including high homogeneity and low auto-fluorescence. This makes it an ideal choice for applications that require high-precision optical splitting.
The beamsplitter features a 50:50 reflectance to transmission ratio, meaning it splits incoming light equally between its reflected and transmitted paths. The coating on the front surface of the beamsplitter is EDM 47-024, which is specifically designed for use in the NIR spectrum.
This beamsplitter is available in a thin lens shape, which offers several advantages over traditional beamsplitters. Thin lens beamsplitters are lighter and less bulky, making them easier to integrate into optical systems. They also reduce the risk of beam distortion, which can occur when light passes through a thick beamsplitter.
