67-633 15mm Dia. x 30mm FL; NIR II Coated; Double-Convex Lens NIR II 750-1550nm
This is a 15mm diameter by 30mm focal length double-convex lens, specifically designed for use in the near-infrared (NIR) spectrum. The lens is sourced from Edmund Optics and is currently in stock.
The lens is made from n-BK7 Schott, a popular optical glass known for its excellent transparency in the visible and near-infrared regions. The double-convex geometry, with radii of curvature of 30.5mm and -30.5mm, provides a broad field of view and minimal distortion. The lens has an effective focal length of 30mm and a center thickness of 4mm, providing a robust and durable structure.
The lens features a standard NIR-II coating on both the front and back surfaces. This coating is designed to enhance transmission in the 750-1550nm range, making it ideal for applications such as night vision, thermal imaging, and spectral analysis. The coating is applied using Edmund Optics' standard curve, ensuring consistent performance and reliability.
