67-479 9.0mm Dia. x 36.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
This is a 67-479 Plano-Convex Lens, a high-quality optical component sourced from Edmund Optics. The lens boasts a 9.0mm diameter and a focal length of 36.0mm, making it suitable for a wide range of applications.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. It is coated with EDM NIR-II std curve on both the front and back surfaces, enhancing its performance in the near-infrared spectrum, specifically between 750nm and 1550nm.
The geometry of the lens is carefully designed with a center thickness of 1.93mm and an edge thickness of 1mm. The lens's inner and outer radii are 0, and its effective focal length (EFL) is 22mm. The radius of curvature (R1) is 11.37mm, and the back focal length (BFL) is 20.73mm.
This lens is a spherical lens, which means it has a spherical surface. The base shape is circular, adding to its versatility in various applications. The lens's design and construction make it an excellent choice for applications that require high-quality optical performance in the near-infrared spectrum.
