67-617 10mm Dia. x 25mm FL; NIR II Coated; Double-Convex Lens NIR II 750-1550nm
This is a 10mm diameter, 25mm focal length double-convex lens, specifically designed for use in the near-infrared (NIR) spectrum. The lens is sourced from Edmund Optics, a leading provider of optical components. It is coated with a NIR II standard curve coating on both the front and back surfaces, enhancing its performance in the 750-1550nm wavelength range.
The lens is made from n-BK7 Schott, a high-quality borosilicate glass known for its excellent optical properties. The base shape is circular, and the geometry includes a 1.51mm edge thickness and a 2.5mm center thickness. The effective focal length (EFL) is 25mm, and the radii of curvature are 25.41mm for the first surface and -25.41mm for the second surface. The back focal length (BFL) is 24.16mm.
This lens is a spherical lens, meaning it has a surface that is a portion of a sphere. The double-convex design, where both surfaces are convex, provides a wide field of view and low spherical aberration. The lens is in stock and ready for immediate use in your optical system.
