This is a 15mm diameter, double-convex lens with a focal length of 20mm, sourced from the renowned optical components vendor, Edmund Optics. The lens is made from n-SF11 Schott, a high-index glass with excellent transmittance across the visible spectrum, making it ideal for applications within the 400-700nm range.
The lens features a standard MgF2 coating on both the front and back surfaces. This coating reduces reflection and increases transmission, particularly in the ultraviolet and visible regions of the spectrum. The front and back focal lengths are 18.99mm and 30.6mm, respectively, providing a wide range of possibilities for optical system design.
The lens geometry includes a center thickness of 3.5mm and an edge thickness of 1.63mm, contributing to its robustness and ease of handling. Despite its compact size, this lens offers impressive performance, making it a versatile choice for various optical applications.
