63-721-INK 10 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=40mm VIS-NIR 400-1000nm
The 63-721-INK is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a diameter of 10 mm, is designed for use in the visible (VIS) and near-infrared (NIR) spectrum, specifically catering to the wavelength range of 400-1000nm.
The lens features a focal length (EFL) of 40mm, making it suitable for a wide range of optical applications. The achromatic design, which combines two different types of glass (N-BK7 and N-SF5), effectively reduces chromatic aberration, ensuring clear and sharp images across the entire spectral range.
The lens geometry includes a thickness of 3.74mm at the edge, with a central thickness of 3mm and a central thickness 'a' of 1.5mm. The radii of curvature are r1=23.66mm, r2=-18.11mm, and r3=-55.78mm. The lens is inked, which aids in its identification and handling.
The lens is coated with edm visnir0sp2002000 on both the front and back surfaces, enhancing its transmission characteristics in the VIS-NIR range. This lens is currently in stock and available for immediate shipping, as indicated by its weblink status.
