46-237 20 mm Dia. N-BK7 λ/4 Concave Spherical Mirror; EFL=20mm Protected Aluminum 400-2000nm

This is a 46-237 20 mm Dia. N-BK7 λ/4 concave spherical mirror, sourced from the renowned optical components vendor, Edmund Optics. The mirror boasts a 20mm focal length (EFL), making it suitable for a wide range of optical applications.

The mirror is fabricated from N-BK7 Schott glass, a popular choice in the optical industry due to its excellent optical properties and high damage threshold. The mirror's base shape is circular, with a diameter of 20mm, providing a broad surface area for light reflection.

The mirror's geometry is characterized by its concave spherical shape, with a radius of curvature (R1) of -40mm. This curvature allows for precise light focusing, making the mirror ideal for use in imaging systems, laser applications, and other optical setups requiring concentrated light beams.

The mirror's coating is a protected aluminum coating, designed to provide high reflectivity across a broad spectrum, from 400nm to 2000nm. This wide spectral range makes the mirror versatile, suitable for use in various applications, including ultraviolet (UV), visible, and infrared (IR) light systems.

The mirror's thickness varies from 3mm at the center to 4.27mm at the edge, providing structural rigidity and minimizing potential distortions caused by external forces. The mirror's design and construction ensure high-quality performance and durability, making it a reliable choice for your optical needs.
