49-480 12mm Dia. x 72mm FL; NIR I Coated; Double-Convex Lens NIR I 600-1050nm

This is a 12mm diameter by 72mm focal length double-convex lens, manufactured by Edmund Optics. The lens is made from n-BK7 Schott glass, a popular choice for its high refractive index and low dispersion. The lens features a standard NIR I coating on both the front and back surfaces, designed for use in the 600-1050nm wavelength range. This coating enhances the lens's performance by reducing surface reflections and increasing transmission in the near-infrared spectrum.

The lens's geometry includes a center thickness of 2.8mm and an edge thickness of 2.31mm, providing a robust structure while maintaining a relatively lightweight design. The front and back radii of curvature are 73.97mm and -73.97mm, respectively, creating a double-convex shape. The back focal length is 71.07mm, and the effective focal length is 72mm.

This lens is suitable for a wide range of applications, including but not limited to, machine vision, scientific research, and industrial inspection. It is currently in stock, according to the vendor's website, making it an ideal choice for immediate requirements.
