45-492-INK 15.0mm Dia. x 22.5mm FL; VIS-NIR; Inked; Plano-Convex Lens VIS-NIR 400-1000nm
The 45-492-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 spectrum, specifically between 400-1000nm. The lens has a front (plano) side that is flat and a back (convex) side that is curved. This design allows for a focal length of 22.5mm, which is the distance from the center of the lens to the point at which light rays converge.
The lens has a center thickness of 3.35mm and an edge thickness of 1.36mm, providing a balance between weight and optical performance. The inner radius is 0mm, and the outer radius is also 0mm, indicating a symmetrical design. The lens is made from n-sf5 schott, a material known for its excellent optical properties.
The lens is coated with edm visnir0sp2002000 on both the front and back sides. This coating is designed to enhance the lens's performance in the visible to near-infrared spectrum, reducing reflections and increasing transmission. The coating is inked, providing additional protection and ease of handling.
