30Q40BS.1 76.2 mm Dia. 50:50 (R:T) UVFS Broadband Dielectric Plate Beamsplitter; t=12.5mm 480-700nm

The 30Q40BS.1 is a high-quality beamsplitter from MKS/Newport, designed for use in a wide range of optical applications. This beamsplitter features a circular geometry with a diameter of 76.2 mm and a thickness of 12.5 mm, making it suitable for use in systems with a substantial optical path.

The beamsplitter is made from UVFS material, identified as MAL-1965 in the Newport material database. This material is known for its excellent optical properties, making it ideal for use in broadband applications. The beamsplitter is designed to operate over a wide wavelength range, from 480 nm to 700 nm, making it a versatile choice for many optical systems.

The beamsplitter features a 50:50 (R:T) split ratio, meaning that it reflects 50% of the incoming light and transmits the other 50%. This makes it suitable for applications where equal distribution of light is required. The beamsplitter's coating is another key feature. The front surface is coated with New BS.1, while the back surface is coated with New NC.1. These coatings are designed to optimize the beamsplitter's performance over its specified wavelength range.

The beamsplitter's physical data includes a reflection of 0.5 on the beamsplitter surface and a transmission of 0.5, further highlighting its 50:50 split ratio. This beamsplitter is currently in stock and available for immediate shipping, as indicated by its valid weblink status.
