63-680 20mm Dia. x 50mm FL; VIS-NIR Coated; Double-Convex Lens VIS-NIR 400-1000nm
The 63-680 is a high-quality double-convex lens, designed and manufactured by Edmund Optics. This lens boasts a 20mm diameter and a focal length of 50mm, making it suitable for a wide range of applications. The lens is constructed from n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility.
The lens features a double-convex geometry, characterized by two spherical surfaces that curve outwards. This design allows for a high refractive power, making the lens ideal for imaging applications. The lens has a center thickness of 3.5mm and an edge thickness of 1.52mm, ensuring structural integrity and durability.
The 63-680 lens is coated with a VIS-NIR coating, specifically the EDM VISNIR0SP2002000 coating on both the front and back surfaces. This coating enhances the lens's performance in the visible and near-infrared spectrum, between 400 and 1000nm. It reduces surface reflections, increases transmission, and improves overall image quality.
