This 87-682 optical mirror, sourced from Edmund Optics, is a 25 mm diameter plano-convex spherical mirror with a protective silver coating. The mirror's design includes a convex base shape, making it a curved mirror, and its geometry is defined by a 400 mm radius of curvature (R1) and a center thickness of 3 mm. The edge thickness is slightly less at 2.81 mm.
The mirror's effective focal length (EFL) is 200 mm, which is a crucial specification for determining how this mirror will interact with other optical elements in a system. The mirror is made from N-BK7 glass, a popular choice in the optical industry due to its excellent optical properties and wide transmission range.
The protective silver coating (edm dprotsil3001000) on the front surface of the mirror is designed to enhance its durability and performance within the wavelength range of 450-10000 nm. This mirror is currently in stock and available for immediate use. For more detailed information, please refer to the vendor's website or contact 3DOptix directly.
