64-061 25 mm Dia. N-BK7 Plano-Convex Spherical Mirror; EFL=15.5mm Enhanced Aluminum 450-650nm

This 25 mm diameter plano-convex spherical mirror, sourced from Edmund Optics, is a high-quality optical component designed for use in a variety of applications. The mirror features an enhanced aluminum coating, optimized for the 450-650nm wavelength range, ensuring excellent reflectivity and performance.

The mirror's geometry is defined by a 2.07mm thickness at the edge, increasing to 4.7mm at the center, providing robustness and stability. The effective focal length (EFL) is 15.5mm, making it suitable for use in focusing and collimating applications. The mirror's curvature is spherical, with a radius of curvature (R1) of 31.01mm, contributing to its focusing capabilities.

The mirror is made from N-BK7 Schott glass, a common and reliable material in optical systems due to its excellent optical properties and low dispersion. This makes the mirror suitable for use in applications where high image quality and low chromatic aberration are required.

The mirror's coating is a crucial aspect of its performance. The enhanced aluminum coating provides high reflectivity and durability, making it suitable for use in harsh environments. The coating is applied to the front surface of the mirror, ensuring optimal performance.
