The 47-717 is a high-quality achromatic doublet lens, boasting a 30 mm diameter and an effective focal length (EFL) of 125mm, 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.
The lens is constructed from two types of Schott glass, N-SK11 and N-SF5, which are carefully selected to minimize chromatic aberration, a common issue in lens systems. The front and back surfaces of the lens are coated with the EDM VIS-0 standard curve coating, enhancing its light transmission capabilities and overall performance.
The lens geometry is meticulously designed, with a central thickness of 4.92mm, an edge thickness of 5.52mm, and inner and outer radii of 0mm. The lens also features a base shape of a circle, and its multiplet design allows for superior optical performance.
