49-500 30mm Dia. x 50mm FL; NIR I Coated; Double-Convex Lens NIR I 600-1050nm
This is a 49-500 double-convex lens, featuring a 30mm diameter and a focal length of 50mm. The lens is sourced from Edmund Optics and is currently in stock. It is designed for use within the near-infrared (NIR) 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's geometry includes a 2mm edge thickness and a 6.55mm center thickness, with a back focal length of 47.82mm. The radii of curvature for the front and back surfaces are 50.56mm and -50.56mm, respectively.
The lens features a standard NIR I coating on both the front and back surfaces. This coating, provided by Edmund Optics, is designed to optimize performance within the NIR spectrum. The coating is part of the standard curve, ensuring consistent performance across a range of applications.
