49-919-INK 15.0mm Dia. x 45.0mm FL; VIS-NIR; Inked; Plano-Convex Lens VIS-NIR 400-1000nm
The 49-919-INK is a plano-convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 15.0mm, is designed for use in the visible to near-infrared (VIS-NIR) spectrum, specifically catering to wavelengths between 400 and 1000nm.
The lens features a front and back coating of edm visnir0sp2002000, which is a broadband anti-reflection coating optimized for the VIS-NIR range. This coating aids in minimizing surface reflections, thereby enhancing the overall transmission of light through the lens.
The lens's geometry includes a thickness of 1.26mm at the edge and 2.5mm at the center. The effective focal length (EFL) is 45.0mm, and the radius of curvature (R1) is 23.26mm. The back focal length (BFL) is 43.35mm, and the lens does not have an inner or outer radius.
This lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The material is known for its low dispersion and high Abbe number, making it suitable for a wide range of optical applications.
