49-518 6.0mm Dia. x -12 FL; NIR I Coated; Plano-Concave Lens 600-1050nm

The 49-518 is a 60mm diameter Plano-Concave Lens with a focal length of -12, sourced from Edmund Optics. This lens is designed for use in the near-infrared spectrum, specifically between 600-1050nm, making it suitable for a wide range of applications in this wavelength range.

The lens is made from n-BK7 Schott, a high-quality borosilicate glass known for its excellent optical properties. It has a diameter of 6mm and a thickness of 2.12mm at the edge, reducing to 1.5mm at the center. The lens's base shape is circular, and it features a spherical geometry, with an inner radius of 0 and an outer radius of 0.

The 49-518 is coated with Edmund Optics' NIR I standard curve coating on both the front and back surfaces. This coating is designed to enhance the lens's performance in the near-infrared spectrum, improving transmission and reducing reflection.

In terms of its optical characteristics, the lens has a front radius of -6.2 and a back focal length of -12.99. This plano-concave design is ideal for use in systems where a diverging lens is required.

The lens is currently in stock and available for purchase directly from the Edmund Optics website, as indicated by its valid weblink status. With its high-quality materials, advanced coating, and precise specifications, the 49-518 is a reliable and versatile choice for any near-infrared optical system.
