67-613 9mm Dia. x 45mm FL; NIR II Coated; Double-Convex Lens NIR II 750-1550nm
The 67-613 is a high-performance spherical lens, boasting a 9mm diameter and a 45mm focal length, making it suitable for a wide range of applications. This lens is sourced from Edmund Optics, a renowned vendor known for their quality optical components.
The lens is designed with a double-convex geometry, featuring a radius of curvature of 46.08mm on both the front and back surfaces. This design results in a high refractive power, enabling the lens to focus light efficiently. The lens has a central thickness of 2.5mm and an edge thickness of 2.06mm, providing robustness and durability.
The lens is crafted from N-BK7 Schott glass, a material renowned for its excellent optical properties and versatility. This material ensures high transmission across a wide spectrum, making it ideal for use in the visible and near-infrared regions.
The lens features a standard NIR-II coating on both the front and back surfaces. This coating enhances the lens's performance in the near-infrared region, specifically between 750nm and 1550nm, by reducing surface reflections and increasing transmission. The coating is designed to follow the standard EDM curve, ensuring consistent performance and compatibility with other optical components.
