This is a 60mm diameter, 72mm focal length Plano-Convex lens, specifically designed for use in the near-infrared spectrum, with a coating optimized for the 600-1050nm range. The lens is sourced from Edmund Optics, a leading vendor in the optical components industry.
The lens is made from N-BK7 Schott glass, a popular material for its high refractive index and low dispersion, making it ideal for imaging applications. The Plano-Convex geometry, where one side is flat and the other is curved, is commonly used to focus light.
The lens has a diameter of 6mm and a thickness of 1.48mm at the edge, increasing to 1.6mm at the center. The effective focal length (EFL) is 72mm, and the radius of curvature (R1) is 37.22mm. The back focal length (BFL) is 70.97mm, and the lens does not have an inner or outer radius.
The lens is coated with Edmund Optics' standard NIR-I coating on both the front and back surfaces. This coating is designed to enhance transmission in the near-infrared region, making it suitable for applications such as night vision, thermal imaging, and spectroscopy.
