38-494 12.0mm Dia. x 25mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm
The 38-494 is a Plano-Convex Lens, a type of spherical lens, with a diameter of 12.0mm and a focal length of 25mm. This lens is sourced from Edmund Optics, a renowned vendor in the optical industry. The lens is designed for use within the visible to near-infrared spectrum, specifically catering to wavelengths between 400 and 1000nm.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. The front and back surfaces of the lens are coated with edm visnir0sp2002000, a specialized coating that enhances its performance within the VIS-NIR spectrum.
The lens's geometry includes a thickness of 1.22mm at the edge and 2.7mm at the center. The inner and outer radii are not specified, suggesting they are not a significant factor in the lens's performance or application. The back focal length is 32.22mm, and the radius of curvature of the first surface is 12.92mm.
The lens's web links are valid and indicate that it is currently in stock, making it readily available for immediate use. This lens is an excellent choice for applications that require a compact, high-performing lens within the VIS-NIR spectrum.
