49-449 3mm Dia. x 6mm FL; VIS-NIR Coated; Double-Convex Lens VIS-NIR 400-1000nm
The 49-449 is a double-convex lens with a 3mm diameter and a 6mm focal length, sourced from Edmund Optics. This lens is designed for use within the visible to near-infrared spectrum, specifically between 400 and 1000nm.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The base shape of the lens is circular, and it features a spherical geometry. The radius of curvature for the first surface (R1) is 5.88mm, while the second surface (R2) has a radius of curvature of -5.88mm. The lens has an effective focal length (EFL) of 6mm, and the back focal length (BFL) is 5.37mm.
The lens is coated with a VIS-NIR coating, specifically edm visnir0sp2002000, on both the front and back surfaces. This coating is designed to enhance the lens's performance within the visible to near-infrared spectrum. The edge thickness of the lens is 1.41mm, while the center thickness is 1.8mm.
This lens is a great option for applications that require a small, high-performance lens within the visible to near-infrared spectrum. It is currently in stock, according to the vendor's website.
