The 63-653 is a high-quality double-convex lens, boasting a 30mm diameter and a focal length of 60mm. This lens is sourced from Edmund Optics, a renowned vendor known for their extensive catalog of optical elements. The lens is designed for use within the near-infrared spectrum, specifically between 600-1050nm, making it ideal for a variety of applications within this range.
The lens is constructed from n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The lens features a standard curvature coating on both the front and back surfaces, specifically the EDM NIR-I std curve. This coating is designed to enhance the lens' performance within the near-infrared spectrum, providing improved transmission and reduced reflection.
The geometry of the lens is carefully designed, with an edge thickness of 1.26mm and a center thickness of 5mm. The lens' inner and outer radii are not specified, indicating that they are not a significant factor in its performance or application. The effective focal length (EFL) is 60mm, and the back focal length (BFL) is 58.33mm.
