47-714 30 mm Dia. N-SSK8/N-SF10 Achromatic Doublet; EFL=60mm VIS 0° 425-675nm

The 47-714 is a high-quality achromatic doublet lens, boasting a 30 mm diameter and an effective focal length (EFL) of 60 mm, specifically designed for the visible light spectrum ranging from 425 to 675 nm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is available for purchase through their official website.

The lens is constructed from two types of Schott glass: N-SSK8 and N-SF10. These materials are carefully selected to minimize chromatic aberration, a common issue in lens systems where different wavelengths of light are focused at different points. By combining these materials, the 47-714 achieves superior image quality with minimal color fringing.

The lens geometry is meticulously designed, with an inner radius of 0 mm, an outer radius of 0 mm, and a central thickness of 8.47 mm. The edge thickness is 7.66 mm, and the first and second radii of curvature are 32.6 mm and -31.81 mm, respectively. The third radius of curvature is -799.64 mm, indicating a complex lens design that ensures optimal performance.

The 47-714 is coated with the EDM VIS-0 standard curve on both the front and back surfaces. This coating enhances the lens's transmission and reduces reflection, thereby improving light transmission and image quality.
