87-659 25 mm Dia. N-BK7 Plano-Convex Spherical Mirror; EFL=150mm Protected Aluminum 400-700nm

This 87-659 optical mirror, sourced from Edmund Optics, is a 25mm diameter N-BK7 plano-convex spherical mirror with a protective aluminum coating that reflects light within the 400-700nm wavelength range. The mirror's geometry is characterized by its 300mm effective focal length (EFL), which is the distance from the mirror's center to the focal point where light rays converge after reflection.

The mirror's base shape is circular, and it has a thickness of 2.74mm at the edge, which gradually increases to 3mm at the center. This design ensures structural rigidity while minimizing unnecessary weight. The mirror's coating, identified as 'edm dprotal300200000', is a protected aluminum coating that enhances the mirror's reflectivity and durability.

This mirror is an excellent choice for applications that require precise light reflection within the specified wavelength range. Its high-quality N-BK7 glass substrate, combined with the protective aluminum coating, ensures reliable and consistent performance. The mirror is currently in stock, as indicated by its weblink status, making it readily available for immediate use.
