BQN4033 40 mm Dia. 50:50 (R:T) N-BK7 Precision Plate Beamsplitter; t=6mm 450-700nm

The BQN4033 is a 40 mm diameter, 6mm thick Plate Beamsplitter from Knight Optical, designed for use in the visible spectrum between 450-700nm. This beamsplitter is a crucial component in optical systems, facilitating the division of an incident light beam into two separate beams with varying intensities.

The BQN4033 features a 50:50 (R:T) split ratio, meaning it reflects 50% of the incident light and transmits the remaining 50%. This balanced split ratio ensures equal distribution of light, making it ideal for applications requiring even light division.

The beamsplitter is made from N-BK7 Schott, a high-quality borosilicate glass known for its excellent optical properties. This material ensures high transmittance, low auto-fluorescence, and excellent environmental stability.

The front surface of the beamsplitter is coated with KNI BV1, while the back surface features KNI AV2 coating. These coatings enhance the beamsplitter's performance by reducing surface reflections and improving transmission.

The BQN4033's thin lens shape allows for easy integration into various optical systems. It is currently in stock and available for immediate purchase through the provided weblink.
