The BQN5033 is a 50 mm diameter, 6mm thick beamsplitter from Knight Optical, designed for use in the visible light spectrum between 450-700nm. This beamsplitter is a part of Knight Optical's Precision Range, known for its high-quality optical components.
The beamsplitter is made of N-BK7, a popular optical glass due to its excellent optical properties and wide transmission range. It features a 50:50 beam splitting ratio, meaning it reflects 50% of the incident light and transmits the remaining 50%. This makes it ideal for applications requiring equal distribution of light.
The front surface of the beamsplitter is coated with KNI BV1, while the back surface is coated with KNI AV2. These coatings enhance the beamsplitter's performance by reducing surface reflections and improving transmission. The beamsplitter's thin lens shape allows for easy integration into various optical systems.
