63-802 20mm Dia. x 40mm FL VIS-NIR Coated; UV Plano-Convex Lens VIS-NIR 400-1000nm
The 63-802 is a 20mm diameter, 40mm focal length plano-convex lens, specifically designed for use in the visible to near-infrared spectrum (VIS-NIR), covering the wavelength range of 400-1000nm. This lens is sourced from Edmund Optics, a leading provider of optical components.
The lens is made from fused silica (mal-1965), a material known for its excellent transparency and low auto-fluorescence in the VIS-NIR range. The front and back surfaces of the lens are coated with a broadband anti-reflection coating (edm visnir0sp2002000), which enhances its transmission capabilities and reduces surface reflections, thereby improving image quality and contrast.
The lens geometry includes a 1.53mm edge thickness and a 4.5mm center thickness, with a 36.92mm back focal length (BFL) and an 18.34mm radius of curvature (R1). The lens has no inner or outer radius, indicating a plano surface on one side and a curved surface on the other.
This lens is suitable for a wide range of applications, including but not limited to, imaging, beam shaping, and laser applications in the VIS-NIR spectrum. It is currently in stock, as indicated by its weblink status, making it readily available for immediate use.
