47-706-INK 18 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=35mm VIS 0° 425-675nm

The 47-706-INK is an 18 mm diameter achromatic doublet lens, designed and manufactured by Edmund Optics. This lens is specifically engineered for use within the visible light spectrum, spanning from 425 to 675 nanometers. The lens boasts an effective focal length (EFL) of 35mm, making it suitable for a wide range of optical applications.

The lens is composed of two primary elements: N-BAF10 and N-SF10 Schott glass. These materials are carefully selected for their optical properties, contributing to the lens's overall performance. The lens is coated with EDMM Vis-0 std curve on both the front and back surfaces, further enhancing its capabilities.

The geometry of the lens is meticulously designed, with a thickness of 5.61mm at the edge and 6.01mm at the center. The center thickness includes an additional 1.6mm 'a' component. The lens's inner and outer radii are 0, indicating a circular shape. The first and second radii of curvature are 24.26mm and -16.23mm, respectively, while the third radius of curvature is -152.99mm.

The lens is available for purchase through the Edmund Optics website, where it is listed as in stock. For more detailed information, including technical specifications and purchasing options, please refer to the provided weblink.
