64-075 25 mm Dia. N-BK7 Plano-Convex Spherical Mirror; EFL=15.5mm Protected Gold 700-10000nm

This 64-075 optical mirror, sourced from Edmund Optics, is a 25 mm diameter N-BK7 Plano-Convex Spherical Mirror with a protective gold coating, designed for use within the wavelength range of 700-10000nm. The mirror boasts an effective focal length (EFL) of 15.5mm, making it suitable for a variety of optical applications.

The mirror's geometry is characterized by a convex shape, with a thickness of 2.07mm at the edge and 4.7mm at the center. The curvature of the mirror is spherical, with a radius (R1) of 31.01mm. This curvature, in combination with the mirror's material and coating, contributes to its high reflectivity and optical performance.

The mirror is made from N-BK7, a high-quality borosilicate glass known for its excellent optical properties. This material is particularly suitable for use in the infrared region, making the mirror ideal for applications such as thermal imaging, spectroscopy, and beam manipulation within this wavelength range.

The mirror's protective gold coating (edm prgold 700-10000) is designed to enhance its durability and optical performance. Gold is a highly reflective material across a wide range of wavelengths, making it an excellent choice for mirrors intended for use in the infrared region. The 'protected' nature of the coating ensures that the mirror's surface is resistant to oxidation and tarnishing, further enhancing its longevity and reliability.
