63-837 25mm Dia. x 25mm FL; VIS-NIR Coated; UV Double-Convex Lens VIS-NIR 400-1000nm
The 63-837 is a high-quality spherical lens, boasting a diameter of 25mm and a focal length of 25mm, sourced from the reputable vendor Edmund Optics. This lens is designed for use within the visible to near-infrared spectrum, spanning 400-1000nm, making it suitable for a wide range of optical applications.
The lens is crafted from fused silica, a material with a high transmittance across a broad spectral range, ensuring optimal performance in its designated spectrum. The front and back surfaces of the lens are coated with the "edm visnir0sp2002000" coating, which is specifically designed for the visible to near-infrared range, further enhancing its performance and durability.
The lens geometry is characterized by its double-convex shape, with radii of curvature of 21.06mm for the first surface and -21.06mm for the second. This shape, combined with the lens's dimensions, results in an effective focal length of 25mm and a back focal length of 20.93mm. The lens has an edge thickness of 2.68mm and a center thickness of 10.9mm, contributing to its robustness and overall optical performance.
