10B20BS.1 25.4 mm Dia. 50:50 (R:T) N-BK7 Broadband Dielectric Plate Beamsplitter; t=6.1mm 480-700nm

The 10B20BS.1 is a high-quality beamsplitter, designed and manufactured by MKS/Newport, a leading vendor in the optical industry. This beamsplitter is characterized by its circular geometry, with a diameter of 25.4 mm, and a thickness of 6.1 mm, making it suitable for a wide range of optical applications.

The beamsplitter is made from N-BK7 Schott, a popular material in the optical industry due to its excellent optical properties. It is designed to operate at a wavelength of 588 nm, but its broadband coating allows it to function effectively within the 480-700 nm range. This broadband functionality makes it a versatile component in many optical systems.

The beamsplitter features a 50:50 (R:T) split ratio, meaning it reflects 50% of the incident light and transmits the remaining 50%. This characteristic is crucial in applications that require equal distribution of light, such as interferometry and beam combining.

The front surface of the beamsplitter is coated with New BS.1, while the back surface is coated with New NC.1. These coatings are designed to enhance the beamsplitter's performance, ensuring high reflectivity and transmissivity within the specified wavelength range.
