BK7-BSP-50.8-400-700-30:70 50.8 mm Dia. N-BK7 70:30 (R:T) Broadband Plate Beamsplitter; t=3mm 400-700nm

This Beam Splitter, sourced from Simtrum, is a high-quality optical component designed for use in a wide range of applications. It features a circular geometry with a diameter of 50.8 mm and a thickness of 3 mm, providing a robust and compact design.

The Beam Splitter is made from n-BK7 Schott, a popular optical material known for its excellent optical properties. This material is particularly suitable for applications that require high transmission and low absorption across a broad spectrum.

The coating on the front surface of the Beam Splitter is sim bs307040070045, which is specifically designed to provide a 70:30 (R:T) broadband split over the wavelength range of 400-700 nm. This means that 70% of the incident light will be reflected, while 30% will be transmitted. This ratio is ideal for many applications, including imaging, interferometry, and beam combining.

The physical data of the Beam Splitter indicates that the reflection at the beamsplitter surface is 0.7, while the transmission is 0.3. This confirms the 70:30 (R:T) split ratio specified by the coating.
