67-459 6.0mm Dia. x 6.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
The 67-459 is a Plano-Convex lens, a type of spherical lens, with a diameter of 6mm and a focal length of 6mm. This lens is sourced from Edmund Optics, a leading vendor in the optical industry, and is currently in stock. The lens is made from n-sf11 Schott, a high-index glass with excellent transmittance in the near-infrared (NIR) region.
The lens features a plano-convex geometry, meaning one side is flat (plano) and the other is curved (convex). The curvature of the convex side is defined by a radius of 4.71mm. The lens has a thickness of 1.42mm at the edge and 2.5mm at the center. The back focal length (BFL) is 4.6mm, and the effective focal length (EFL) is the same as the focal length, at 6mm.
The 67-459 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 NIR region, specifically between 750nm and 1550nm, making it suitable for applications such as night vision, thermal imaging, and spectroscopy.
