47-490 9mm Dia. x 45mm FL; VIS 0deg Coated; Double-Convex Lens VIS 0deg 425-675nm
The 47-490 is a high-quality Double-Convex Lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a 9mm diameter and 45mm focal length, is designed for use within the visible light spectrum, specifically catering to the wavelength range of 425-675nm.
The lens boasts a base shape of a circle, with a front and back surface curvature that is spherical in nature. The front surface is coated with an edm vis-0 std curve coating, while the back surface also features the same edm vis-0 std curve coating. This dual-coating ensures improved light transmission and reduced surface reflections, enhancing the overall performance of the lens.
The lens has a thickness of 2.06mm at the edge and 2.5mm at the center. The effective focal length (EFL) is 45mm, and the back focal length (BFL) is 44.17mm. The first radius of curvature (R1) is 46.08mm, and the second radius of curvature (R2) is -46.08mm. The lens is made from n-bk7 schott material, a common choice for its excellent optical properties and versatility.
The lens is currently in stock and available for immediate purchase. For more detailed information, including technical specifications and purchasing options, please refer to the provided weblink.
