47-716 30 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=100mm VIS 0° 425-675nm

The 47-716 is a high-quality achromatic doublet lens, boasting a 30 mm diameter and an effective focal length (EFL) of 100 mm, specifically designed for the visible light spectrum ranging from 425 to 675 nm. This lens is sourced from the renowned optical components manufacturer, Edmund Optics, and is available for purchase through their official website.

The lens is constructed from two types of glass: N-BK7 and N-SF5, both from Schott, ensuring excellent optical performance. The N-BK7, a borosilicate crown glass, is known for its low dispersion and exceptional homogeneity, making it a popular choice for various optical applications. The N-SF5, a dense flint glass, offers high refractive index and Abbe number, further enhancing the lens's achromatic properties.

The 47-716 features a sophisticated geometry, with an inner radius of 0 mm, an outer radius of 0 mm, and a center thickness of 8.25 mm. The edge thickness is 8.31 mm, while the front and back surfaces are coated with Edmund Optics' standard anti-reflective coating (VIS-0 std curve) for improved light transmission and reduced surface reflections.

This lens is classified as a multiplet, indicating that it consists of multiple elements. The curvature of the lens surfaces is defined by the radii r1 (-61.36 mm), r2 (44.3 mm), and r3 (-128.9 mm). The lens's shape is circular, ensuring uniform light distribution and minimal optical aberrations.
