68-400 12.5 mm Dia. 60:40 (R:T) N-BK7 Plate Beamsplitter; t=3mm NIR 700-1100nm

This 68-400 Beamsplitter, sourced from Edmund Optics, is a circular plate with a diameter of 12.5 mm and a thickness of 3 mm. It is designed for use in the near-infrared (NIR) spectrum, specifically for wavelengths between 700 and 1100 nm.

The beamsplitter is made of N-BK7, a high-quality borosilicate glass known for its excellent optical properties. This material is often used in a variety of optical applications due to its low coefficient of thermal expansion and high homogeneity.

The beamsplitter features a 60:40 reflectance to transmission ratio, meaning that approximately 60% of the incident light will be reflected while 40% will be transmitted. This ratio is constant for the specified wavelength range.

The front surface of the beamsplitter is coated with EDM 68-400, a proprietary coating developed by Edmund Optics. This coating enhances the beamsplitter's performance in the NIR spectrum.

The beamsplitter is designed in the shape of a thin lens, which helps to minimize optical aberrations and distortions. This makes it an ideal choice for applications that require high precision and accuracy.
