47-025 12.5 x 17.5 mm 50:50 (R:T) N-BK7 Plate Beamsplitter; t=3mm NIR 700-1100nm

The 47-025 12.5 x 17.5 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 12.5 millimeters in width and 17.5 millimeters in height. It has a thickness of 3 millimeters, providing robustness and stability during operation. The material of the beamsplitter is N-BK7, a type of borosilicate glass known for its excellent optical properties, including high transparency and low autofluorescence.

The coating on the beamsplitter is EDM 47-024, which is applied to the front surface. This coating is designed to ensure a 50:50 split of the incident light, with half of the light being reflected and the other half transmitted. This makes the beamsplitter ideal for applications that require equal distribution of light, such as interferometry, holography, and beam combining.

The physical data of the beamsplitter indicates that the reflection and transmission coefficients are both 0.5, further confirming its 50:50 light splitting capability. The beamsplitter is currently in stock and available for immediate purchase, as indicated by its weblink status.
