68-372 25 x 38 mm 20:80 (R:T) N-BK7 Plate Beamsplitter; t=3mm NIR 700-1100nm

The 68-372 is a high-quality beam splitter, designed and manufactured by Edmund Optics, a leading global supplier of optical components. This specific model boasts a rectangular shape with dimensions of 25 x 38 mm, making it suitable for a wide range of optical applications. The beam splitter has a thickness of 3mm, providing excellent durability and stability.

The beam splitter is made from N-BK7, a popular optical glass due to its excellent optical properties. This material is known for its low optical dispersion and high Abbe number, making it an ideal choice for applications that require high-precision optics. The N-BK7 Schott material ID ensures that the beam splitter meets the highest standards of quality and performance.

The 68-372 features a 20:80 (R:T) beam splitting ratio, meaning that 20% of the incident light is reflected while 80% is transmitted. This ratio is particularly useful for applications that require a higher transmission rate, such as imaging and laser systems. The beam splitter is designed to operate in the near-infrared (NIR) region, specifically between 700 and 1100nm, making it suitable for a wide range of NIR applications.

The front surface of the beam splitter is coated with EDM 68-364, a proprietary coating developed by Edmund Optics. This coating enhances the beam splitter's performance by reducing surface reflections and improving transmission. The physical data of the beam splitter indicates a reflection of 0.2 and a transmission of 0.8, further highlighting its high-performance capabilities.
