63-723 10 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=100mm VIS-NIR 400-1000nm
The 63-723 is a high-quality achromatic doublet lens, sourced from the renowned optical component vendor, Edmund Optics. This lens is specifically designed for use in the visible (VIS) and near-infrared (NIR) spectrum, spanning 400-1000nm.
The lens features a 10mm diameter and an effective focal length (EFL) of 100mm, making it suitable for a wide range of applications that require high-precision optics. The lens is constructed from two types of glass, N-BK7 and N-SF5, both from Schott, ensuring superior optical performance.
The geometry of the lens is carefully crafted, with a central thickness of 2.5mm and edge thickness of 3.7mm. The lens features three radii of curvature: r1 at 60.99mm, r2 at -43.74mm, and r3 at -130.98mm. These parameters contribute to the lens's excellent chromatic correction and minimal spherical aberration.
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 enhances the lens's transmission in the VIS-NIR range, reduces surface reflections, and increases overall optical efficiency.
