49-250 9mm Dia. x 13.5mm FL; UV-AR Coated; UV Double-Convex Lens UV-AR 250-425nm
This UV-AR coated, double-convex lens, offered by Edmund Optics, boasts a 9mm diameter and a focal length of 13.5mm. Its base shape is circular, and it is designed to operate at a wavelength of 587.6nm. The lens is made from fused silica (mal-1965) and features a standard UV curve coating on both the front and back surfaces.
The lens's geometry includes an edge thickness of 1.52mm and a center thickness of 3.3mm. The front and back radii are 11.84mm and -11.84mm, respectively, resulting in a back focal length of 12.32mm. The lens's inner and outer radii are both zero, indicating a uniform curvature.
The UV-AR coating on this lens is designed to filter ultraviolet light while allowing visible light to pass through. This makes it ideal for applications that require the blocking of harmful UV radiation. The lens's double-convex shape, meanwhile, allows for a wide field of view and low distortion, making it suitable for imaging applications.
Please note that the lens's specifications are subject to change, and it is always a good idea to check the vendor's website for the most up-to-date information. The link to the product page on Edmund Optics' website is provided in the item data for your convenience.
