67-508 12.7mm Dia. x 15.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
The 67-508 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 12.7mm 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) while the other is curved (convex). The curvature of the convex side is defined by a radius of 9.05mm, and the lens has a central thickness of 3.8mm and an edge thickness of 1.29mm. The effective focal length (EFL) of the lens is 17.5mm, and the back focal length (BFL) is 15mm.
The 67-508 lens is coated with Edmund Optics' NIR-II standard curve coating on both the front and back surfaces. This coating enhances the lens' performance in the near-infrared (NIR) spectrum, specifically between 750nm and 1550nm, making it suitable for various applications in this spectral range.
