67-509 12.7mm Dia. x 19.1mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
The 67-509 is a Plano-Convex lens with a diameter of 12.7mm and a focal length of 19.1mm, sourced from Edmund Optics. This lens is designed for use in the near-infrared (NIR) spectrum, specifically between 750nm and 1550nm, making it suitable for a wide range of applications in this spectral range.
The lens is made from n-sf11 Schott, a high-index glass with excellent transmission properties in the NIR region. The front and back surfaces of the lens are coated with edm nir-ii std curve, a proprietary coating developed by Edmund Optics specifically for NIR applications. This coating enhances the lens's transmission capabilities and reduces surface reflections, thereby improving overall system performance.
The lens geometry includes a 1.72mm edge thickness and a 4mm center thickness. The inner and outer radii are 0, indicating a simple spherical shape. The effective focal length (EFL) is 12.7mm, and the back focal length (BFL) is 10.46mm. The lens is currently in stock and available for immediate shipping.
