67-533 20.0mm Dia. x 30.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
The 67-533 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 20.0mm and a focal length of 30.0mm, making it a compact and efficient optical component. The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion.
The lens features a plano-convex geometry, meaning one side is flat (plano) and the other side is curved (convex). The radius of curvature for the curved side is 37.22mm, and the back focal length is 70.05mm. The lens has an effective focal length (EFL) of 72mm, which is the distance from the lens's center to its focal point.
The 67-533 lens is coated with Edmund Optics' NIR-II standard curve on both the front and back surfaces. This coating enhances the lens's performance in the near-infrared (NIR) spectrum, specifically between 750nm and 1550nm. This makes the lens ideal for applications that require high-quality imaging or light transmission in the NIR range, such as night vision, thermal imaging, or spectral analysis.
