67-497-INK 12.0mm Dia. x 24.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 67-497-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 12.0mm, is designed for use in the near-infrared (NIR) spectrum, specifically between 750nm and 1550nm. The lens features a front and back coating of edm nir-ii std curve, which enhances its performance in the NIR range.
The lens has a thickness of 1.58mm at the edge and 3.5mm at the center, providing a base shape that is circular. The effective focal length (EFL) of this lens is 20mm, and the radius of curvature (R1) is 10.34mm. The back focal length (BFL) is 17.69mm, and the lens does not have an inner or outer radius.
The lens is made of n-bk7 schott, a material known for its excellent optical properties. The wavelength for this lens is 587.6nm. The lens is inked, which is a common practice to facilitate handling and identification during the manufacturing and assembly process.
This lens is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website at https://www.edmundoptics.com/f/nir-ii-coated-plano-convex-pcx-lenses/14105/.
