This product is a curved mirror (concave) with a base shape of a circle, offering a diameter of 50.8 mm and a thickness edge of 10 mm. The mirror's effective focal length (EFL) is -250 mm, and its radius of curvature (R1) is -500 mm.
The mirror is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties. It is designed to operate at a wavelength of 800 nm.
The mirror features an enhanced silver coating on the front side, specifically the "eks enhsil600110045" coating. This coating ensures high reflectivity across the 600-1100 nm spectral range, making it suitable for various applications, including but not limited to, laser systems, interferometry, and optical imaging.
