68-422 25 mm Dia. 80:20 (R:T) N-BK7 Plate Beamsplitter; t=3mm NIR 700-1100nm
The 68-422 is a 25 mm diameter N-BK7 Plate Beamsplitter, designed for use in the near-infrared (NIR) spectrum, specifically between 700 and 1100 nanometers. This beamsplitter is manufactured by Edmund Optics, a leading provider of optical components.
The beamsplitter features an 80:20 ratio for reflection to transmission, making it ideal for applications where a majority of the light needs to be reflected while still allowing some transmission. The front surface of the beamsplitter is coated with EDM 68-418, a proprietary coating developed by Edmund Optics to enhance its performance in the NIR spectrum.
The beamsplitter has a circular geometry with a diameter of 25 mm and a thickness of 3 mm, making it suitable for a wide range of optical systems. Its N-BK7 Schott material provides excellent optical performance, with a high refractive index and low dispersion.
In terms of physical data, the beamsplitter has a reflection coefficient of 0.8 and a transmission coefficient of 0.2. This means that 80% of the incident light will be reflected, while 20% will be transmitted. This ratio is maintained consistently across the NIR spectrum, ensuring reliable performance in a variety of applications.
