43-833 12 mm Dia. N-BK7 Concave-Convex Spherical Mirror; EFL=12mm Protected Gold 700-10000nm

This 12 mm diameter concave mirror, sourced from Edmund Optics, is a versatile optical component designed for a wide range of applications. Its concave shape, defined by a radius of curvature of -24 mm, allows for precise focusing and reflection of light. The mirror's geometry also includes a thickness edge of 3 mm, contributing to its overall durability and stability.

The mirror is made from N-BK7, a high-quality borosilicate glass known for its excellent optical properties. This material is particularly suitable for applications that require high homogeneity and low auto-fluorescence. The mirror's effective focal length (EFL) is 12 mm, which is the distance from the mirror's surface at which parallel light rays converge after reflection.

The mirror's front surface is coated with a protected gold coating, specifically designed for use in the 700-10000 nm wavelength range. This coating ensures high reflectivity and durability, making it ideal for applications such as infrared spectroscopy, thermal imaging, and other infrared-based technologies.
