The 83-417 is a high-quality achromatic doublet lens, designed and manufactured by Edmund Optics. This lens is specifically engineered for use in the visible (VIS) and near-infrared (NIR) spectrum, with a wavelength range of 400-1000nm. The lens boasts a 12.7 mm diameter and an effective focal length (EFL) of 125mm, making it suitable for a wide range of optical applications.
The lens is constructed from two types of glass: N-BK7 and N-SF5, both from Schott. The use of these materials ensures high optical quality and minimal chromatic aberration. The lens features a complex geometry, with three radii of curvature (r1, r2, and r3) and varying thicknesses at the edge, center, and center-a. The edge thickness is 6.11mm, the center thickness is 4.5mm, and the center-a thickness is 2mm.
The lens is coated with Edmund Optics' VIS-NIR coating (edm visnir0sp2002000), which is applied to both the front and back surfaces. This coating is designed to enhance the lens' performance in the VIS-NIR spectrum, reducing reflection and increasing transmission.
