67-630 15mm Dia. x 20mm FL; NIR II Coated; Double-Convex Lens NIR II 750-1550nm
This is a 15mm diameter by 20mm focal length double-convex lens, specifically designed for use in the near-infrared (NIR) spectrum. The lens is sourced from Edmund Optics and is currently in stock.
The lens is made from n-SF11 Schott, a material known for its excellent optical properties in the NIR range. It has a standard curve coating on both the front and back surfaces, specifically the EDM NIR-II std curve, which is designed to enhance its performance in the NIR II spectrum, specifically between 750nm and 1550nm.
The lens has a base shape of a circle and features a spherical geometry. The radius of curvature for the first surface is 30.6mm, while for the second surface it is -30.6mm. The back focal length of the lens is 18.99mm, and the effective focal length is 20mm. The lens has a center thickness of 3.5mm and an edge thickness of 1.63mm.
This lens is a great option for those looking for high-quality, NIR-optimized optical components. Its double-convex design and Schott n-SF11 material make it suitable for a wide range of applications, while its EDM NIR-II std curve coating ensures optimal performance in the NIR II spectrum.
