33-369 25.0mm Dia. x 400.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
This is a Plano-Convex lens, type of spherical lens with a circular base shape, sourced from Edmund Optics. The lens has a diameter of 25.0mm and a focal length of 400.0mm, making it suitable for a variety of applications. The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and high transmittance in the visible and near-infrared regions.
The lens features a plano-convex geometry, meaning one side is flat (plano) and the other side is curved (convex). The radius of curvature of the curved surface is 103.36mm, and the lens has an effective focal length (EFL) of 200mm. The lens thickness at the edge is 2.44mm, while the center thickness is 3.2mm. The back focal length (BFL) of the lens is 197.89mm.
The lens is coated with Edmund Optics' standard NIR-II coating on both the front and back surfaces, designed for the 750-1550nm wavelength range. This coating enhances the lens's performance in the near-infrared spectrum, making it ideal for applications such as night vision, thermal imaging, and spectroscopy.
