63-832 12mm Dia. x 35mm FL; VIS-NIR Coated; UV Double-Convex Lens VIS-NIR 400-1000nm
This is a 12mm diameter, 35mm focal length double-convex lens, specifically designed for the visible to near-infrared (VIS-NIR) spectrum, with a wavelength of 587.6nm. The lens is sourced from the reputable vendor, Edmund Optics.
The lens is made from fused silica, a high-quality material known for its excellent transmission properties and durability. It features a double-convex geometry, with radii of curvature of 31.57mm for the first surface and -31.57mm for the second surface. This geometry provides a large numerical aperture, making it suitable for a wide range of applications.
The lens is coated with a broadband anti-reflection coating, specifically the "edm visnir0sp2002000" coating, on both the front and back surfaces. This coating is designed to reduce surface reflections and increase transmission in the VIS-NIR spectral range, from 400nm to 1000nm. The coating ensures high-quality images with minimal loss of light due to reflection.
The lens has an edge thickness of 2.14mm and a center thickness of 3.29mm, providing structural rigidity and resistance to damage. The back focal length is 33.85mm, which is an important parameter for designing optical systems.
