10B20NP.27 25.4 mm Dia. 50:50 (R:T) N-BK7 Laser Line Non-Polarizing Plate Beamsplitter; t=6.1mm 780nm

The 10B20NP.27 is a non-polarizing beamsplitter from MKS/Newport, designed for use with laser line applications. This beamsplitter boasts a circular geometry with a diameter of 25.4 mm and a thickness of 6.1 mm, providing a robust and compact solution for various optical systems.

The beamsplitter is made from N-BK7, a high-quality borosilicate glass known for its excellent optical properties, including low autofluorescence and high transmittance in the visible and near-infrared regions. This specific model is designed for use at a wavelength of 780 nm.

The coating on the front surface of the beamsplitter is Newport's NP.27, a non-polarizing coating that ensures equal reflection and transmission for both s- and p-polarized light. This 50:50 (R:T) beamsplitter is ideal for applications that require equal distribution of light between the reflected and transmitted paths.

The physical data of the beamsplitter indicates a reflection of 0.5 and a transmission of 0.5 for the base shape, further emphasizing its balanced light distribution capabilities. The beamsplitter is currently in stock and available for immediate purchase, as indicated by its valid weblink status.
