This is a 6.0mm diameter Plano-Convex lens, type VIS-NIR, sourced from the renowned optical components vendor, Edmund Optics. The lens is inked and features a focal length (FL) of 7.5mm, making it suitable for a wide range of applications within the visible to near-infrared spectrum (400-1000nm).
The lens is made of n-sf11 Schott, a high-index glass with excellent optical properties. It has a base shape of circle, with a thickness at the edge of 1.68mm and a center thickness of 2.5mm. The effective focal length (EFL) is 7.5mm, and the radius of curvature (R1) is 5.89mm. The back focal length (BFL) is 6.1mm, and both the inner and outer radii are 0mm.
The lens is coated with edm visnir0sp2002000 on both the front and back surfaces, providing superior visible to near-infrared performance. The coating is designed to enhance the lens's durability and maintain its optical properties over time.
