67-477 9.0mm Dia. x 22.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
The 67-477 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a 9.0mm diameter and a focal length of 22.0mm, 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.
The lens features a plano-convex geometry, meaning one side is flat (plano) and the other side is curved (convex). The radius of curvature for the curved side is 7.75mm, and the back focal length is 13.02mm. The lens has a central thickness of 3mm and an edge thickness of 1.56mm, providing a robust structure.
The 67-477 lens is coated with Edmund Optics' NIR-II standard curve coating on both the front and back surfaces. This coating enhances the lens' performance in the near-infrared spectrum, specifically between 750nm and 1550nm, making it ideal for applications such as night vision, thermal imaging, and spectral analysis.
