38-544-INK 25.4mm Dia. x 100.0mm FL; VIS-NIR; Inked; Plano-Convex Lens VIS-NIR 400-1000nm

The 38-544-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 25.4mm, is designed for use in the visible to near-infrared (VIS-NIR) spectrum, specifically catering to wavelengths between 400nm and 1000nm.

The lens's geometry is defined by a thickness of 1.42mm at the edge, increasing to 3mm at the center, and an effective focal length (EFL) of 100mm. The front surface of the lens has a radius of curvature of 51.68mm, while the back focal length (BFL) measures 92.02mm. The lens is made from N-BK7 Schott, a popular optical glass known for its excellent optical properties.

The lens features a VIS-NIR coating, denoted as 'edm visnir0sp2002000', on both the front and back surfaces. This coating is designed to enhance the lens's performance in the VIS-NIR spectrum, reducing surface reflections and improving transmission.
