63-718 10 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=20mm VIS-NIR 400-1000nm

The 63-718 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 Schott glass, N-BAF10 and N-SF10, which are renowned for their excellent optical properties.

The lens has a diameter of 10mm and an effective focal length (EFL) of 20mm, making it a compact yet powerful optical component. The lens features a sophisticated geometry, with a thickness of 3.91mm at the edge and 4mm at the center. The first and second radii of curvature are 14.15mm and -8.38mm respectively, while the third radius of curvature is -71.22mm. This complex geometry is designed to minimize optical aberrations and deliver sharp, clear images.

The lens is coated with Edmund Optics' proprietary 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.

The 63-718 is a multiplet lens, meaning it is composed of multiple elements. This design allows for the precise correction of chromatic aberrations, a common issue in optical systems. The lens is available for purchase directly from Edmund Optics, and the company's website indicates that it is currently in stock.
