63-688 40mm Dia. x 40mm FL; VIS-NIR Coated; Double-Convex Lens VIS-NIR 400-1000nm

The 63-688 is a high-quality double-convex lens, boasting a 40mm diameter and a focal length of 40mm, sourced from the renowned optical vendor, Edmund Optics. This lens is designed for use within the visible to near-infrared spectrum (VIS-NIR), spanning wavelengths of 400-1000nm, making it suitable for a wide range of optical applications.

The lens features a base shape of a circle and is constructed from the high-performance glass material, n-SF11 Schott. This material ensures excellent optical transmission and low auto-fluorescence, making it ideal for applications that require high-resolution imaging and precise light control.

The 63-688 lens comes equipped with a VIS-NIR coating on both the front and back surfaces, identified as 'edm visnir0sp2002000'. This coating enhances the lens's performance by minimizing surface reflections and improving light transmission, thereby reducing light loss and increasing the overall efficiency of the optical system.

The lens's geometry includes an edge thickness of 1.74mm and a center thickness of 8.5mm. The front and back radii of curvature are 60.85mm and -60.85mm, respectively, resulting in a back focal length of 37.54mm. The lens has an effective focal length (EFL) of 40mm, which is the distance from the lens's principal point to its focal point.
