68-404 25 mm Dia. 60:40 (R:T) N-BK7 Plate Beamsplitter; t=3mm NIR 700-1100nm

The 68-404 is a 25 mm diameter beamsplitter, specifically designed for use in the near-infrared (NIR) spectrum, with a wavelength range of 700-1100nm. This beamsplitter is manufactured by Edmund Optics, a leading global manufacturer and supplier of optical components.

The beamsplitter is made from N-BK7 glass, a high-quality borosilicate crown glass known for its excellent optical properties. The glass has a thickness of 3mm, providing durability and stability. The beamsplitter is designed in a thin plate configuration, which reduces unwanted reflections and scattering, enhancing its performance in various applications.

The beamsplitter features a 60:40 reflectance to transmission ratio, meaning that approximately 60% of the incident light is reflected while 40% is transmitted. This ratio is specifically designed for applications where a balance between reflection and transmission is required. The front surface of the beamsplitter is coated with EDM 68-400, a proprietary coating developed by Edmund Optics to enhance its performance in the NIR spectrum.

This beamsplitter is suitable for various applications, including but not limited to, interferometry, spectroscopy, beam combining, and imaging systems. It is currently in stock, as indicated by its weblink status, and more information about the product can be found on the Edmund Optics website.
