67-494 12.0mm Dia. x 15.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
The 67-494 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 12.0mm and a focal length of 15.0mm, making it a compact yet powerful 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 is curved (convex). The radius of curvature of the convex side is 51.68mm, and the back focal length is 98.02mm. The lens has an effective focal length (EFL) of 100mm, which is the distance from the lens's principal point to its focal point.
The 67-494 lens is coated with Edmund Optics' NIR-II standard curve coating 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. The coating ensures high transmission and low reflection, making it ideal for applications that require optimal performance in the NIR range.
