63-711-INK 10 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=100mm VIS 0° 425-675nm

The 63-711-INK is a high-quality achromatic doublet lens, boasting a 10 mm diameter and an effective focal length (EFL) of 100mm, specifically designed for the visible light spectrum ranging from 425 to 675nm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is available for purchase through their website.

This achromatic doublet is composed of two types of glass, N-BK7 and N-SF5, both from Schott, which are renowned for their optical quality. The lens is designed to correct chromatic aberration, a common issue in lenses where different wavelengths of light are focused at different points, leading to color fringing. By combining two different types of glass, this doublet effectively minimizes this aberration, providing clear, sharp images across the entire visible spectrum.

The lens geometry is meticulously designed, with a diameter of 10 mm, a thickness at the edge of 3.7 mm, and a center thickness of 2.5 mm. The inner and outer radii are 0 mm, and the lens features radii of curvature of 60.99 mm and -43.74 mm on the first and second surfaces, respectively, and -130.98 mm on the third surface. The lens is coated with EDM Vis-0 std curve on both the front and back surfaces, enhancing its light transmission capabilities and overall performance.
