67-636 15mm Dia. x 60mm FL; NIR II Coated; Double-Convex Lens NIR II 750-1550nm
This is a 15mm diameter, double-convex lens with a focal length of 60mm, specifically designed for use in the near-infrared (NIR) spectrum. The lens is sourced from Edmund Optics, a leading provider of optical components, and is currently in stock.
The lens is made from n-BK7 Schott, a high-quality borosilicate glass known for its excellent optical properties. It features a double-convex geometry, with radii of curvature of 61.5mm for both the front and back surfaces. This shape provides a high degree of focusing power, making it suitable for a wide range of applications.
The lens has an effective focal length (EFL) of 60mm and a back focal length (BFL) of 59mm. The center thickness is 3mm, while the edge thickness is 2.08mm. The lens is coated with Edmund Optics' standard NIR-II coating on both the front and back surfaces, which enhances its performance in the 750-1550nm wavelength range.
