63-721 10 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=40mm VIS-NIR 400-1000nm
The 63-721 is a high-quality achromatic doublet lens, sourced from the renowned optical components vendor, Edmund Optics. This lens 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 10mm diameter and an effective focal length (EFL) of 40mm, making it suitable for a wide range of optical applications. The achromatic design, which incorporates two different types of glass (N-BK7 and N-SF5), effectively minimizes chromatic aberration, ensuring sharp and clear images across the entire spectral range.
The lens geometry is meticulously crafted, with a center thickness of 3mm and edge thickness of 3.74mm. The radii of curvature are R1 = 23.66mm, R2 = -18.11mm, and R3 = -55.78mm, further enhancing the lens's optical performance.
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's transmission in the VIS-NIR range, reducing reflection and improving overall light efficiency.
