68-364 12.5 mm Dia. 20:80 (R:T) N-BK7 Plate Beamsplitter; t=3mm NIR 700-1100nm
The 68-364 is a 12.5 mm diameter beamsplitter, designed for use in the near-infrared (NIR) spectrum, specifically between 700 and 1100 nanometers. This beamsplitter is manufactured by Edmund Optics, a leading provider of optical components.
The beamsplitter is made from N-BK7 glass, a type of borosilicate crown glass known for its excellent optical properties and high damage threshold. The beamsplitter has a thickness of 3mm, providing robustness and stability.
The beamsplitter features a 20:80 (R:T) coating, which means that 20% of the incident light is reflected, while 80% is transmitted. This coating is applied to the front surface of the beamsplitter, as indicated in the item data.
The beamsplitter is designed in a circular geometry, with a diameter of 12.5mm. This shape allows for versatile use in various optical systems.
In terms of physical data, the beamsplitter has a reflection of 0.2 and a transmission of 0.8, aligning with its 20:80 (R:T) coating.
