20B20BS.2 50.8 mm Dia. 50:50 (R:T) N-BK7 Broadband Dielectric Plate Beamsplitter; t=9.4mm 700-950nm

The 20B20BS.2 is a high-quality beamsplitter, specifically designed for broadband applications, with a diameter of 50.8 mm and a thickness of 9.4 mm. This beamsplitter is sourced from the reputable vendor MKS/Newport, ensuring reliability and performance.

The beamsplitter is made from N-BK7, a popular optical glass due to its excellent optical properties and wide transparency range. The front surface of the beamsplitter is coated with a new BS.2 coating, while the back surface is coated with a new NC.2 coating. These coatings are designed to optimize the beamsplitter's performance in the 700-950nm wavelength range.

The beamsplitter is designed to split incoming light equally, reflecting 50% and transmitting 50% of the incident light. This 50:50 (R:T) ratio makes it ideal for a wide range of applications where balanced light splitting is required.

The beamsplitter's geometry is that of a thin lens, which helps to minimize optical aberrations and distortions. This, combined with its broadband coating, makes the 20B20BS.2 a versatile and high-performing beamsplitter for various optical systems.
