67-488 10.0mm Dia. x 30.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
The 67-488 is a Plano-Convex lens, part of the Spherical Lens category, sourced from Edmund Optics. This lens boasts a 10.0mm diameter and a 30.0mm focal length, making it suitable for a wide range of applications. The lens is made from n-BK7 Schott, a popular material in the optical industry due to its excellent optical properties and versatility.
The lens features a front and back coating of EDM NIR-II STD Curve, a specialized coating designed for use in the near-infrared (NIR) spectrum, specifically between 750nm and 1550nm. This coating enhances the lens's performance in the NIR range, making it ideal for applications such as night vision, thermal imaging, and spectral analysis.
The geometry of the lens includes a 1.71mm thickness at the edge, increasing to 3.0mm at the center. The lens's inner radius is 0mm, while the outer radius is also 0mm. The lens's effective focal length (EFL) is 20mm, and the radius of curvature (R1) is 10.34mm. The back focal length (BFL) is 18.03mm.
