49-917-INK 12.0mm Dia. x 20.0mm FL; VIS-NIR; Inked; Plano-Convex Lens VIS-NIR 400-1000nm
The 49-917-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 visible to near-infrared (VIS-NIR) spectrum, specifically between 400-1000nm. The lens has a focal length (FL) of 20.0mm, which is the distance from the center of the lens to the point at which light rays converge.
The lens's geometry includes a thickness of 1.58mm at the edge and 3.5mm at the center. The front surface has a radius of curvature (R1) of 10.34mm, while the back focal length (BFL) is 17.69mm. The lens is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility.
The lens features a visnir coating, specifically 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. The coating status is in stock, ensuring prompt delivery upon order.
