67-575 40.0mm Dia. x 60.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
This is a Plano-Convex Lens, sourced from the renowned optical components vendor, Edmund Optics. The lens, identified as the 67-575, is designed with a 40.0mm diameter and a focal length of 60.0mm, making it suitable for a wide range of applications.
The lens is constructed from N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The lens's geometry includes a thickness of 3.78mm at the edge and 6mm at the center, with an effective focal length (EFL) of 100mm. The radius of curvature (R1) is 51.68mm, and the back focal length (BFL) is 96.01mm.
The 67-575 lens features a NIR II coating on both the front and back surfaces. This coating, part of Edmund Optics' standard curve, is specifically designed for the Near-Infrared II spectral range, covering 750-1550nm. This coating enhances the lens's performance in the NIR spectrum, reducing reflection and increasing transmission.
