67-531-INK 20.0mm Dia. x 20.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 67-531-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 20.0mm, is designed for use in the Near-Infrared II (NIR II) spectrum, specifically for wavelengths between 750nm and 1550nm.
The lens features a front and back coating of edm nir-ii std curve, which is specifically designed for use in the NIR II spectrum. This coating enhances the lens' performance in this region, providing superior image quality and light transmission.
The lens has a thickness of 1.25mm at the edge and 3.57mm at the center. The effective focal length (EFL) of the lens is 36mm, and the radius of curvature (R1) is 18.62mm. The back focal length (BFL) is 33.65mm, and the lens does not have an inner or outer radius.
The lens is made from n-bk7 schott, a high-quality optical glass that offers excellent transmission in the visible and near-infrared regions. This material is known for its excellent optical properties, making it a popular choice for a wide range of optical applications.
The lens is in stock and available for immediate purchase. For more information, please visit the provided weblink.
