48-757 20.0mm Dia. x 20.0mm FL; NIR I Coated; Plano-Convex Lens NIR I 600-1050nm
This product is a Plano-Convex Lens, offered by the renowned optical vendor, Edmund Optics. The lens, identified as the 48-757, is a spherical lens with a base shape of a circle. It boasts a diameter of 20.0mm and a focal length of 20.0mm, making it a compact yet powerful optical component.
The lens is constructed from the material n-sf11 schott, a common choice in the industry due to its desirable optical properties. The geometry of the lens is such that the thickness at the edge is 1.0mm, while the thickness at the center is 4.6mm. The effective focal length (EFL) is 20.0mm, and the radius of curvature (R1) is 15.7mm. The back focal length (BFL) is 17.42mm, and both the inner and outer radii are 0mm.
The lens features a coating on both the front and back surfaces, specifically the EDM NIR-I STD curve. This coating is designed to optimize the lens' performance within the wavelength range of 600-1050nm, making it suitable for near-infrared applications.
