67-452 4.5mm Dia. x 9.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
The 67-452 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a 4.5mm diameter and a focal length of 9.0mm, making it suitable for a wide range of applications. The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion.
The lens features a front and back coating of edm nir-ii std curve, which is specifically designed for use in the near-infrared (NIR) spectrum, specifically between 750nm and 1550nm. This coating enhances the lens's performance in the NIR range, making it an ideal choice for applications such as night vision, thermal imaging, and spectral analysis.
The lens has a central thickness of 2.38mm and an edge thickness of 1.8mm, providing a balance between weight and durability. The inner and outer radii are both 0mm, indicating a uniform curvature. The lens's effective focal length (EFL) is 9mm, which, combined with its diameter, gives it a high numerical aperture (NA), enhancing its light-gathering capabilities.
