67-553 25.0mm Dia. x 175.0mm 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 and a diameter of 25.0mm. The lens is sourced from the renowned optical vendor, Edmund Optics. It boasts a long focal length of 175.0mm, making it suitable for applications requiring a high degree of magnification or precision.
The lens is constructed from the high-quality material, N-BK7 Schott, which is known for its excellent optical properties and durability. The geometry of the lens includes a thickness of 2.77mm at the edge and 4.3mm at the center, with an effective focal length (EFL) of 100mm. The lens's front radius of curvature (R1) is 51.68mm, and the back focal length (BFL) is 97.17mm.
The lens features a NIR II coating on both the front and back surfaces, as per the EDM NIR-II standard curve. This coating enhances the lens's performance in the near-infrared spectrum, specifically between 750nm and 1550nm, making it ideal for applications such as night vision, thermal imaging, and spectral analysis.
