49-897 12.0mm Dia. x 20.0mm FL; VIS 0deg Coated; Plano-Convex Lens VIS 0° 425-675nm
The 49-897 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a 12.0mm diameter and a 20.0mm focal length, making it suitable for a wide range of optical applications. The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion.
The lens features a standard VIS 0° coating on both the front and back surfaces. This coating enhances the lens's performance in the visible light spectrum, specifically between 425-675nm. The coating reduces reflection and increases transmission, thereby improving the overall efficiency and quality of the optical system.
The geometry of the lens is meticulously designed. The lens has an inner radius of 0mm and an outer radius of 0mm, indicating a plano surface on one side and a curved surface on the other. The curvature of the lens is defined by a radius of 10.34mm, and the back focal length is 17.69mm. The lens has a thickness of 1.58mm at the edge and 3.5mm at the center.
