67-982 6.0mm Dia. x -6 FL; NIR II Coated; Plano-Concave Lens 750-1550nm
The 67-982 is a 6.0mm diameter Plano-Concave Lens, boasting a high-quality NIR II coating and a focal length of -6. This lens is sourced from Edmund Optics, a renowned vendor known for their extensive catalog of optical elements.
The lens is designed with a base shape of Circular, and its geometry includes a thickness edge of 2.22, a thickness center of 1.5, and an effective focal length (EFL) of -6. The concave surface has a radius of curvature (R1) of -4.71, and the back focal length (BFL) is -6.84. The lens does not have any inner or outer radius specified.
The lens is made from n-sf11 Schott, a material known for its excellent optical properties. The NIR II coating, applied to both the front and back surfaces, enhances the lens' performance in the near-infrared spectrum, specifically between 750 and 1550nm. This coating is standard for Edmund Optics' NIR II product line, ensuring consistent performance and quality.
