49-450 3mm Dia. x 9mm FL; VIS-NIR Coated; Double-Convex Lens VIS-NIR 400-1000nm
The 49-450 is a double-convex lens with a 3mm diameter and a 9mm focal length, sourced from 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 constructed from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. This material ensures high-quality imaging and minimal chromatic aberration. The lens features a front and back coating of edm visnir0sp2002000, a broadband anti-reflection coating that enhances transmission within the specified wavelength range.
The geometry of the lens includes an edge thickness of 1.35mm and a center thickness of 1.6mm. The front and back radii are 9.02mm and -9.02mm respectively, contributing to the lens's double-convex shape. The back focal length is 8.46mm, and the effective focal length is 9mm. The lens's base shape is circular, and it does not have any inner or outer radii.
This lens is a spherical lens, which is a type of lens where the two surfaces are parts of spheres. Spherical lenses are the simplest type of lens and are commonly used in various applications due to their simplicity and availability.
