This 87-670 optical mirror, sourced from Edmund Optics, is a 25 mm diameter N-BK7 Plano-Convex Spherical Mirror with an effective focal length (EFL) of 150mm. The mirror's base shape is circular, and it features an enhanced aluminum coating designed for optimal performance within the 450-650nm wavelength range.
The mirror's geometry includes a 2.74mm thickness at the edge and a 3mm thickness at the center. The curvature of the mirror is spherical, with a radius (R1) of 300mm. This mirror is a Curved Mirror (Convex) type, which means it reflects light outwards, causing parallel rays to diverge.
The N-BK7 Schott material used in this mirror is a popular choice for its excellent optical properties and high damage threshold. The mirror's coating, enhanced aluminum, is known for its high reflectivity and durability.
