47-242 25 mm Dia. 30:70 (R:T) N-BK7 Plate Beamsplitter; t=3mm NIR 700-1100nm

The 47-242 is a 25 mm diameter beam splitter, specifically designed for use in the near-infrared (NIR) spectrum, with a wavelength range of 700-1100nm. This beam splitter is sourced from Edmund Optics, a leading global manufacturer and supplier of optical components.

The beam splitter is made from N-BK7 glass, a high-quality borosilicate crown glass known for its excellent optical properties. The glass has a diameter of 25mm and a thickness of 3mm, making it a robust and durable option for various optical applications.

The beam splitter features a 30:70 (R:T) coating, which refers to the ratio of reflection to transmission. This coating is applied to the front surface of the beam splitter and is identified as ED48-389 in the Edmund Optics catalog. This coating ensures a 30% reflection and 70% transmission of the incident light, making it ideal for applications where balanced transmission and reflection are required.

The beam splitter is designed in a thin lens shape, which helps to minimize optical aberrations and distortions. This feature, combined with its high-quality N-BK7 glass construction and precise coating, makes the 47-242 an excellent choice for a wide range of optical systems, including interferometers, spectrometers, and imaging systems.
