BQN4008 25 x 40 mm 50:50 (R:T) N-BK7 Precision Plate Beamsplitter; t=6mm 450-700nm

This is the BQN4008 Precision Plate Beamsplitter, a high-quality optical component sourced from Knight Optical. It is a rectangular beam splitter with dimensions of 25 x 40 mm and a thickness of 6mm, designed for use in the visible light spectrum, specifically between 450 and 700nm.

The beamsplitter is made from N-BK7, a popular optical glass known for its excellent optical properties. This material is often used in high-precision applications due to its low coefficient of thermal expansion and high homogeneity. The beamsplitter features a 50:50 split ratio, meaning it evenly divides incoming light between its reflection and transmission paths.

The front surface of the beamsplitter is coated with KNI BV1, a broadband anti-reflection coating that reduces surface reflections and improves transmission. The back surface is coated with KNI AV2, a coating that enhances reflectivity. This combination of coatings ensures optimal performance for the beamsplitter's intended use.

The beamsplitter's thin lens shape allows for easy integration into optical systems. It is currently in stock and available for immediate purchase from Knight Optical. For more information, please refer to the provided weblink.
