49-451 3mm Dia. x 3mm FL; NIR I Coated; Double-Convex Lens NIR I 600-1050nm
The 49-451 is a high-quality double-convex lens, sourced from the renowned optical vendor, Edmund Optics. This lens is specifically designed for use within the near-infrared (NIR) spectrum, with a wavelength range of 600-1050nm, making it ideal for a wide range of applications in this spectral region.
The lens features a 3mm diameter and a focal length of 3mm, providing a compact and efficient optical solution. The double-convex geometry, with radii of curvature of 3.5mm for both the front and back surfaces, ensures a high level of optical performance. The center thickness of the lens is 2.3mm, while the edge thickness is 1.64mm, providing robustness and durability.
The lens is made from n-SF5 Schott, a high-quality optical glass known for its excellent transmission properties in the NIR region. This, combined with the standard NIR I coating on both the front and back surfaces, ensures high transmission and low reflection across the operational wavelength range.
The item data also provides the effective focal length (EFL) of the lens, which is 3mm, and the back focal length (BFL), which is 2.21mm. The inner and outer radii are both 0mm, indicating a uniform curvature across the lens surface.
