63-656 40mm Dia. x 40mm FL; NIR I Coated; Double-Convex Lens NIR I 600-1050nm

This is a 40mm diameter, 40mm focal length double-convex lens, specifically designed for use in the near-infrared (NIR) spectrum, with a wavelength of 587.6nm. The lens is sourced from Edmund Optics, a leading provider of optical components.

The lens is made from n-SF11 Schott, a high-index glass that offers excellent optical performance. It features a standard NIR I coating on both the front and back surfaces, which is specifically designed to enhance performance in the 600-1050nm range. This coating helps to reduce reflection and increase transmission, improving the overall efficiency and quality of the optical system.

The lens has a center thickness of 8.5mm and an edge thickness of 1.74mm, providing a good balance between weight and durability. The front and back radii of curvature are 60.85mm and -60.85mm respectively, giving it a double-convex shape. The back focal length is 37.54mm, and the effective focal length is 40mm.

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, making it an ideal choice for those needing a reliable and high-performing NIR lens.
