67-517 15.0mm Dia. x 20.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
This is a 15.0mm diameter by 20.0mm focal length plano-convex lens, specifically designed for use in the near-infrared (NIR) spectrum. The lens is sourced from Edmund Optics and is currently in stock. It is made from n-SF5 Schott, a material known for its excellent optical properties in the NIR range.
The lens features a standard curve coating on both the front and back surfaces, specifically the EDM NIR-II std curve. This coating is designed to optimize performance in the NIR II spectrum, which spans from 750nm to 1550nm. The lens has a center thickness of 5.5mm and an edge thickness of 2.16mm, providing a balance between weight and optical performance.
The lens's geometry includes a 10.09mm radius of curvature on the convex side and a 11.71mm back focal length. The effective focal length is 15mm, making this lens suitable for a wide range of applications that require high-quality NIR performance. The lens is spherical in shape, ensuring excellent image quality and low distortion.
