49-478 12mm Dia. x 36mm FL; NIR I Coated; Double-Convex Lens NIR I 600-1050nm
The 49-478 is a high-quality double-convex lens, 12mm in diameter and 36mm in focal length, sourced from the renowned optical components vendor, Edmund Optics. This lens is designed for use within the near-infrared (NIR) spectrum, specifically between 600 and 1050 nanometers, making it suitable for a wide range of applications within this wavelength range.
The lens is constructed from Schott's n-BK7 glass, a popular material in optical systems due to its excellent optical properties and versatility. The lens features a standard curve coating on both the front and back surfaces, specifically Edmund Optics' NIR I coating. This coating enhances the lens' performance within the NIR spectrum, improving transmission and reducing unwanted reflections.
The geometry of the lens is carefully designed, with a center thickness of 3.3mm and an edge thickness of 2.31mm. The lens's front and back radii are 36.65mm and -36.65mm respectively, contributing to its double-convex shape. The effective focal length (EFL) is 36mm, and the back focal length (BFL) is 34.9mm. The lens's inner and outer radii are both 0mm, indicating a circular shape with no additional curvature.
