32-870 12mm Dia. x 36mm FL; MgF2 Coated; Double-Convex Lens MgF2 400-700nm
This is a high-quality double-convex lens, sourced from the renowned optical components manufacturer, Edmund Optics. The lens, identified as the 32-870, boasts a 12mm diameter and a focal length of 36mm, making it suitable for a wide range of optical applications.
The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. It has a refractive index of 1.5168 at 587.6nm, which contributes to its high-performance capabilities.
The lens features a front and back coating of MgF2, a material known for its low refractive index and excellent optical properties. This coating is standard across Edmund Optics' products and is designed to provide high transmission across the 400-700nm range, making it ideal for use in various applications, including but not limited to, imaging systems, beam shaping, and laser applications.
The lens's geometry is another notable feature. It has an edge thickness of 2.31mm and a center thickness of 3.3mm, with an effective focal length (EFL) of 36mm. The radii of curvature for the first and second surfaces are 36.65mm and -36.65mm, respectively, while the back focal length (BFL) is 34.9mm. The lens's base shape is circular, and it has no inner or outer radius.
