87-668 25 mm Dia. N-BK7 Plano-Convex Spherical Mirror; EFL=50mm Enhanced Aluminum 450-650nm

The 87-668 is a 25 mm diameter Plano-Convex Spherical Mirror, sourced from the renowned optical components vendor, Edmund Optics. This mirror is designed for use in the visible spectrum, with a specified wavelength of 588 nm.

The mirror's geometry is characterized by a convex shape, with a 100 mm radius of curvature (R1). The mirror's thickness varies from 2.22 mm at the edge to 3 mm at the center, providing structural rigidity and resistance to deformation.

The mirror is crafted from N-BK7, a high-quality borosilicate glass known for its excellent optical properties. This material is often chosen for its low optical dispersion and high Abbe number, making it suitable for a wide range of optical applications.

The mirror's coating is an enhanced aluminum coating, specifically designed for the 450-650 nm range. This coating enhances the mirror's reflectivity, ensuring optimal performance in its intended wavelength range. The coating is applied to the front surface of the mirror, as indicated by the "front" specification in the coating data.

The mirror's EFL, or Effective Focal Length, is 50 mm. This parameter is crucial in determining the mirror's magnification and is a key factor in its optical performance.

According to the vendor's website, the mirror is currently in stock, ensuring quick delivery and minimal lead times for your optical projects. The item data also includes a weblink to the vendor's product page for easy reference and further details.
