63-719 10 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=25mm VIS-NIR 400-1000nm
The 63-719 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 is constructed from two types of glass, N-BK7 and N-SF5, both from Schott, ensuring superior optical performance.
The lens has a diameter of 10mm and an effective focal length (EFL) of 25mm, making it suitable for a wide range of optical applications. The lens features a multilayer anti-reflection coating, specifically the edm visnir0sp2002000 coating, on both the front and back surfaces. This coating reduces surface reflections, increases transmission, and enhances overall optical performance.
The lens geometry includes a center thickness of 3.5mm, an edge thickness of 3.76mm, and three radii of curvature (r1, r2, and r3) that are precisely engineered to minimize chromatic aberration and deliver sharp, clear images. The lens is designed in a circular shape and is classified as a multiplet due to its multiple elements.
