67-545-INK 25.0mm Dia. x 40.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 67-545-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 25.0mm, is designed for use in the Near-Infrared II (NIR II) spectrum, specifically for wavelengths between 750 and 1550nm.
The lens features a front and back coating of edm nir-ii std curve, which is a standard coating for NIR II applications. This coating enhances the lens' performance in the NIR II spectrum, providing superior transmission and reducing unwanted reflections.
The lens has a thickness of 2.43mm at the edge and 8mm at the center. The effective focal length (EFL) is 25mm, and the radius of curvature (R1) is 16.82mm. The back focal length (BFL) is 20.22mm, and the lens does not have an inner or outer radius.
This lens is made from n-sf5 schott, a high-quality optical material known for its excellent transmission properties in the NIR II spectrum. The lens is in stock and available for immediate purchase from the Edmund Optics website.
