86-919 75.0mm Dia. x 250.0mm FL; NIR I Coated; Plano-Convex Lens NIR I 600-1050nm
This is a Plano-Convex Lens, type NIR I, offered by Edmund Optics with a diameter of 75.0mm and a focal length of 250.0mm. The lens is designed for use within the near-infrared spectrum, specifically between 600 and 1050nm.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens features a spherical shape, with a front radius of curvature of 129.2mm and a back focal length of 244.73mm. The lens has a thickness of 2.44mm at the edge and 8mm at the center.
The lens 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' performance within the near-infrared spectrum, improving transmission and reducing reflection. According to the vendor, the coating and the lens are both in stock, ensuring quick delivery.
