47-663 12.5 mm Dia. N-SSK8/N-SF10 Achromatic Doublet; EFL=30mm VIS 0° 425-675nm

The 47-663 is a high-quality achromatic doublet lens, boasting a 12.5 mm diameter and an effective focal length (EFL) of 30mm. This lens is designed for use within the visible light spectrum, specifically catering to wavelengths between 425nm and 675nm.

The lens is composed of two distinct materials, N-SSK8 and N-SF10, both sourced from the reputable optical manufacturer Schott. These materials are carefully selected for their specific refractive indices and dispersion properties, which contribute to the lens's excellent chromatic correction capabilities.

The 47-663 features a sophisticated geometry, with a thickness of 4.39mm at the edge and 4.5mm at the center. The lens's inner and outer radii are optimized for superior performance, with values of 0mm and 0mm, respectively. The lens's first and second radii are 15.97mm and -15mm, respectively, while the third radius is -528.23mm.

The lens is coated with the EDM VIS-0 standard curve on both the front and back surfaces. This coating enhances the lens's transmission capabilities within the visible light spectrum, further optimizing its performance for a wide range of applications.

The 47-663 is available for purchase from Edmund Optics, and the provided weblink indicates that it is currently in stock. This lens is a versatile and reliable choice for any application that requires a high-performance achromatic doublet within the visible light spectrum.
