45-853 25 mm Dia. 50:50 (R:T) N-BK7 Plate Beamsplitter; t=3mm NIR 700-1100nm
The 45-853 is a 25 mm diameter beamsplitter, specifically designed for use in the near-infrared (NIR) spectrum, with a wavelength range of 700-1100nm. This beamsplitter is manufactured by Edmund Optics, a leading provider of optical components. The item data indicates that this beamsplitter is in stock, and you can find more information about it on the Edmund Optics website using the provided weblink.
This beamsplitter is a 50:50 type, meaning it reflects 50% of the incident light and transmits the remaining 50%. The reflection and transmission coefficients are physical properties of the beamsplitter, and they are determined by the coating applied to the optical surface. In this case, the coating on the front surface of the beamsplitter is EDM 47-024.
The beamsplitter is made of N-BK7 glass, a common material for optical components due to its excellent optical properties and availability. The glass has a thickness of 3mm, which is a standard value for thin beamsplitters. The beamsplitter's geometry is circular, with a diameter of 25mm, making it suitable for a wide range of optical applications.
