G344202000 15 x 20 mm N-BK7 Broadband 50:50 (R:T) Plate Beamsplitter; t=2mm NIR 700-1200nm

This beamsplitter, model G344202000, is a precision optical component manufactured by Qioptiq Photonics. It is designed for use in the near-infrared (NIR) spectrum, specifically for wavelengths between 700 and 1200 nanometers. The beamsplitter is rectangular in shape, with dimensions of 15 x 20 mm, and has a thickness of 2 mm.

The beamsplitter is made from N-BK7, a type of borosilicate glass manufactured by Schott. This material is known for its excellent optical properties, making it a popular choice for a wide range of optical applications. The beamsplitter features a broadband 50:50 (R:T) coating, which means it reflects 50% of the incident light and transmits the remaining 50%. This coating is applied to both the front and back surfaces of the beamsplitter.

The front surface of the beamsplitter is coated with qio bbbs50tbpnir45, a coating specifically designed for use in the NIR spectrum. This coating ensures high reflectivity and low absorption across the specified wavelength range. The back surface of the beamsplitter is coated with qio bbar arb2nirnbk7, a coating that provides high transmittance and low reflectance in the NIR spectrum. This coating ensures that the transmitted light is not significantly affected by reflections from the back surface of the beamsplitter.

In terms of its physical characteristics, the beamsplitter has a shape that is classified as "Thin Lens". This shape is typically used for beamsplitters that are designed to be used in conjunction with other optical elements, such as lenses or mirrors. The beamsplitter's physical data indicates that its reflection and transmission coefficients are both 0.5, which is consistent with its broadband 50:50 (R:T) coating.

The beamsplitter is currently in stock and available for purchase. More information, including technical specifications and purchasing details, can be found on the Qioptiq Photonics website.
