67-458 5.0mm Dia. x 20.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
This is a Plano-Convex Lens, a type of spherical lens, sourced from the renowned optical vendor, Edmund Optics. The lens has a diameter of 5.0mm and a focal length of 20.0mm, making it a compact yet powerful optical component.
The lens is made from the high-quality material n-BK7 Schott, a borosilicate glass known for its excellent optical properties, including high transmission in the visible and near-infrared regions. This makes the lens suitable for a wide range of applications, particularly in the near-infrared spectrum of 750-1550nm.
The lens features a standard curve coating on both the front and back surfaces, specifically the EDM NIR-II std curve. This coating enhances the lens's performance in the near-infrared region, providing improved transmission and reduced reflection. The coating also offers protection against environmental factors, ensuring the longevity and durability of the lens.
The geometry of the lens includes a thickness of 1.19mm at the edge and 1.5mm at the center. The lens's inner and outer radii are 0, indicating a plano-convex shape. The radius of curvature (R1) is 10.34mm, and the back focal length (BFL) is 19.02mm.
