67-623 12mm Dia. x 18mm FL; NIR II Coated; Double-Convex Lens NIR II 750-1550nm
This is a 12mm diameter by 18mm focal length double-convex lens, specifically designed for use in the near-infrared (NIR) spectrum. The lens is sourced from Edmund Optics, a reputable vendor known for their high-quality optical components.
The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. It features a standard NIR II coating on both the front and back surfaces, which enhances its performance in the 750-1550nm wavelength range. This coating helps to reduce surface reflections, increase transmission, and improve overall image quality.
The lens has a center thickness of 3.48mm and an edge thickness of 1.42mm, providing a robust structure while maintaining a relatively compact form factor. The front and back radii of curvature are 18.01mm and -18.01mm respectively, contributing to its double-convex shape. The back focal length (BFL) is 16.81mm, and the effective focal length (EFL) is 18mm.
This lens is ideal for applications that require high-performance in the NIR spectrum, such as night vision, thermal imaging, and scientific research. It is in stock and ready for immediate use. For more information, please refer to the vendor's website using the provided weblink.
