35-942 25 mm Dia. 50:50 (R:T) N-BK7 Plate Beamsplitter; t=1mm VIS 400-700nm

The 35-942 is a 25 mm diameter 50:50 (R:T) Plate Beamsplitter, designed and manufactured by Edmund Optics. This beamsplitter is made from N-BK7 Schott glass, a popular material known for its excellent optical properties and versatility. The beamsplitter has a thickness of 1mm, making it a thin lens, which can be advantageous in certain optical system designs.

The beamsplitter is designed to operate within the visible light spectrum, specifically between 400-700nm. It features a 50:50 reflection to transmission ratio, meaning it reflects 50% of the incident light and transmits the remaining 50%. This makes it an ideal choice for applications that require equal distribution of light, such as interferometry, beam combining, or imaging systems.

The front surface of the beamsplitter is coated with EDMD 47-021, a proprietary coating developed by Edmund Optics. This coating enhances the beamsplitter's performance by reducing surface reflections and improving transmission. The coating also provides excellent environmental stability, ensuring the beamsplitter maintains its performance characteristics even under harsh conditions.
