This is a 67-466 Plano-Convex Lens, a high-quality optical component sourced from Edmund Optics. The lens boasts a 6.0mm diameter and a focal length of 24.0mm, 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 has a refractive index of 1.5168 at 587.6nm, which contributes to its high-performance capabilities.
The lens features a plano-convex geometry, meaning one side is flat while the other is curved. The curvature of the lens is defined by a radius of 10.85mm, which is the radius of the curvature of the curved surface. This geometry is commonly used in optical systems due to its ability to focus light efficiently.
The lens is coated with Edmund Optics' standard NIR-II coating on both the front and back surfaces. This coating is designed to enhance the lens' performance in the near-infrared region, specifically between 750nm and 1550nm. The coating helps to reduce surface reflections, thereby improving transmission and overall system efficiency.
The lens has a central thickness of 1.42mm and an edge thickness of 1mm. The effective focal length (EFL) of the lens is 21mm. The back focal length (BFL) is 20.06mm, which is the distance from the rear surface of the lens to its focal point.
