This is a 67-474 Plano-Convex Lens, a high-quality optical component sourced from Edmund Optics. The lens has a circular base shape with a 9.0mm diameter and a 13.5mm focal length, making it suitable for a wide range of applications.
The lens is made from n-sf11 Schott, a material known for its excellent optical properties. It has a refractive index of 1.8116 at 587.6nm, which contributes to its high-performance capabilities. The lens features a plano-convex geometry, with a 1.28mm edge thickness and a 2.7mm center thickness. The effective focal length (EFL) is 10mm, and the radius of curvature (R1) is 7.85mm. The back focal length (BFL) is 8.49mm.
The lens is coated with Edmund Optics' NIR-II standard curve on both the front and back surfaces. This coating enhances its performance in the near-infrared spectrum, specifically between 750nm and 1550nm. The coating ensures high transmission and low reflection, making it ideal for applications that require optimal performance in the NIR range.
