68-366 12.5 x 17.5 mm 20:80 (R:T) N-BK7 Plate Beamsplitter; t=3mm NIR 700-1100nm

The 68-366 Beam Splitter is a high-quality optical component sourced from Edmund Optics, designed for use in the near-infrared (NIR) spectrum, specifically between 700 and 1100 nanometers. This beamsplitter is rectangular in shape, with dimensions of 12.5 x 17.5 millimeters, and has a thickness of 3 millimeters.

The beamsplitter is made from N-BK7, a popular optical glass from Schott, known for its excellent optical properties and wide transparency range. This material is particularly suitable for use in the NIR spectrum, ensuring high transmission and low absorption within the specified wavelength range.

The beamsplitter features a 20:80 (R:T) coating, which refers to the ratio of reflection to transmission. In this case, 20% of the incident light is reflected, while 80% is transmitted. This coating is applied to the front surface of the beamsplitter, as indicated by the "edm 68-364" coating parameter.

The beamsplitter is designed in the shape of a thin lens, which can be beneficial in certain optical systems due to its reduced thickness and weight. This can help minimize optical aberrations and improve the overall performance of the system.
