63-641 15mm Dia. x 45mm FL; NIR I Coated; Double-Convex Lens NIR I 600-1050nm
The 63-641 is a high-quality double-convex lens, 15mm in diameter and 45mm in focal length, designed for use in the near-infrared spectrum. This lens is sourced from Edmund Optics, a leading global manufacturer of optical components.
The lens is made from N-BK7 Schott glass, a popular choice for its high refractive index and low dispersion, making it ideal for a wide range of optical applications. The lens features a standard NIR I coating on both the front and back surfaces, enhancing its performance in the 600-1050nm wavelength range.
The geometry of the lens includes a 1.77mm thickness at the edge and a 3mm thickness at the center. The effective focal length (EFL) is 45mm, while the back focal length (BFL) is 44mm. The first and second radii of curvature are 45.99mm and -45.99mm, respectively. The lens has no inner or outer radius.
This lens is a spherical lens, meaning it has a curved surface that is a portion of a sphere. The double-convex design, with curvature on both sides, provides a wide field of view and low spherical aberration.
