BQN6355 40 x 65 mm 50:50 (R:T) N-BK7 Precision Plate Beamsplitter; t=8mm 450-700nm

The BQN6355 is a precision plate beamsplitter, designed and manufactured by Knight Optical, a leading supplier of optical components. This beamsplitter is characterized by its rectangular shape, with dimensions of 40 x 65 mm, and a thickness of 8mm, making it suitable for a wide range of optical applications.

The beamsplitter is made from N-BK7, a high-quality borosilicate glass known for its excellent optical properties. This material is particularly suitable for applications in the visible spectrum, as indicated by the beamsplitter's specified wavelength range of 450-700nm.

The BQN6355 features a 50:50 beam splitting ratio, meaning it reflects 50% of the incident light and transmits the remaining 50%. This characteristic is consistent across both the front and back surfaces of the beamsplitter, which are coated with KNI BV1 and KNI AV2 coatings, respectively. These coatings are designed to enhance the beamsplitter's performance and durability.

The beamsplitter's thin lens shape is another notable feature, contributing to its versatility and ease of integration into various optical systems. The physical data provided indicates a reflection of 0.5 and a transmission of 0.5, further highlighting the beamsplitter's balanced beam splitting capability.
