48-661 5.0mm Dia. x 7.5mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm
The 48-661 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a 5.0mm diameter and a focal length of 7.5mm, making it suitable for a variety of applications. The lens is fabricated from n-SF11 Schott, a high-index glass with excellent transmittance in the visible and near-infrared regions, specifically designed for use in the 400-1000nm spectrum.
The lens features a front and back coating of edm visnir0sp2002000, a VIS-NIR coating that enhances its performance in the visible and near-infrared ranges. This coating is designed to reduce surface reflections and increase transmission, thereby improving the overall efficiency and quality of the optical system in which the lens is used.
The lens has a center thickness of 1.9mm and an edge thickness of 1.34mm, providing a balance between compactness and durability. The inner and outer radii are 0mm, indicating a uniform curvature across the lens surface. The lens's base shape is circular, contributing to its versatility in various applications.
