87-677 25 mm Dia. N-BK7 Plano-Convex Spherical Mirror; EFL=12.5mm Protected Silver 450-10000nm

This is a 25 mm diameter Plano-Convex Spherical Mirror, designed and manufactured by Edmund Optics. The mirror boasts a focal length (EFL) of 12.5mm, making it suitable for a wide range of optical applications.

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

The mirror's surface is coated with a protected silver coating, which provides high reflectivity across a broad spectrum, from 450nm to 10000nm. This makes it ideal for use in applications that require high reflectivity over a wide range of wavelengths.

The mirror has a thickness of 1.65mm at the edge and 5mm at the center. This asymmetrical design helps to reduce spherical aberration, improving the overall quality of the optical system.

The mirror is sourced from Edmund Optics, a leading manufacturer of optical components. The weblink provided is valid and the mirror is currently in stock, ensuring quick and easy acquisition for your optical project.
