This is a 67-464 Plano-Convex Lens, a high-quality optical component sourced from Edmund Optics. The lens boasts a 6.0mm diameter and a focal length of 18.0mm, 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 (plano) and the other is curved (convex). The radius of curvature for the convex side is 7.75mm, and the back focal length is 13.68mm. The lens has an edge thickness of 1.4mm and a center thickness of 2mm, providing robustness and durability.
The lens is coated with Edmund Optics' NIR-II standard curve coating on both the front and back surfaces. This coating enhances its 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.
