48-731 9.0mm Dia. x 45.0mm FL; NIR I Coated; Plano-Convex Lens NIR I 600-1050nm
The 48-731 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a 9.0mm diameter and a focal length of 45.0mm, making it suitable for a wide range of applications. The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high homogeneity.
The lens features a front and back coating of EDM NIR-I STD Curve, a specialized coating designed for use in the near-infrared spectrum, specifically between 600-1050nm. This coating enhances the lens's performance in the NIR range, improving transmission and reducing reflection.
The geometry of the lens includes a thickness of 1.1mm at the edge and 1.54mm at the center. The inner radius is 0, and the outer radius is also 0, indicating a plano surface on one side and a curved surface on the other. The radius of curvature of the curved surface is 23.26mm, and the back focal length is 43.98mm.
This lens is a versatile optical component, ideal for applications that require high-quality imaging or light transmission in the near-infrared spectrum. Its robust construction, high-quality materials, and advanced coatings make it a reliable choice for various optical systems.
