This is a 67-462 Plano-Convex Lens, a high-quality optical component sourced from Edmund Optics. The lens boasts a 6.0mm diameter and a focal length of 12.0mm, 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 curved side is 5.17mm, and the back focal length is 8.82mm. The lens has a central thickness of 1.8mm and an edge thickness of 0.84mm, providing robustness and durability.
The lens is coated with Edmund Optics' standard NIR-II coating on both the front and back surfaces. This coating is designed for the near-infrared (NIR) spectrum, specifically for the 750-1550nm range, enhancing its performance in NIR applications.
