This item is a Plano-Convex Lens, sourced from the reputable optical components vendor, Edmund Optics. The lens boasts a 12.5mm diameter and a 20mm focal length, making it suitable for a wide range of optical applications.
The lens is made from the high-quality material, n-BK7 Schott, which is renowned for its excellent optical properties. This material ensures high transmission and low dispersion, making it an ideal choice for many optical systems.
The lens features a standard coating on both the front and back surfaces. The coating, referred to as 'edm vis-0 std curve', is designed to provide superior performance within the visible light spectrum, specifically between 425-675nm. This coating enhances the lens's durability and resistance to environmental factors, while also reducing surface reflections.
The geometry of the lens includes a 1.4mm edge thickness and a 3.5mm center thickness. The inner and outer radii are both 0mm, indicating a flat surface on one side and a curved surface on the other. The curvature of the lens is defined by a radius of 10.34mm, and the back focal length is 17.69mm.
