G344148000 50 mm Dia. N-BK7 Broadband 50:50 (R:T) Plate Beamsplitter; t=6mm VIS-NIR 450-1000nm

The G344148000 is a high-quality beamsplitter plate, designed and manufactured by Qioptiq Photonics. This beamsplitter is part of their broadband series, optimized for use in the visible (VIS) and near-infrared (NIR) spectrum, specifically between 450 and 1000 nanometers.

The beamsplitter features a circular geometry with a diameter of 50 millimeters and a thickness of 6 millimeters. It is made from N-BK7, a popular borosilicate glass known for its excellent optical properties, including a high Abbe number and low optical dispersion. This makes it an ideal material for a wide range of optical applications.

The beamsplitter's coating is a crucial component, enhancing its performance in specific wavelength ranges. In this case, the front surface of the beamsplitter is coated with Qio BBBS50TBPVISNIR4, a proprietary coating developed by Qioptiq. This coating ensures a 50:50 split (R:T) of the incident light, providing a balanced transmission and reflection rate.

The beamsplitter's shape is that of a thin lens, which not only contributes to its compact design but also minimizes optical aberrations. This makes it suitable for use in various optical systems where precise beam splitting is required.
