49-310-INK 6.25 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=40mm VIS-NIR 400-1000nm
The 49-310-INK is a high-quality achromatic doublet lens, designed and manufactured by Edmund Optics. This lens, with a diameter of 6.25 mm, is specifically engineered for use in the visible (VIS) and near-infrared (NIR) spectrum, spanning from 400 to 1000nm. The lens boasts an effective focal length (EFL) of 40mm, making it suitable for a wide range of optical applications.
The lens is composed of two elements, made from N-BK7 and N-SF5 Schott glass, respectively. These materials were chosen for their excellent optical properties, contributing to the lens' high performance. The lens features a front and back coating of EDm VIS-NIR 0SP2002000, further enhancing its optical capabilities.
The lens geometry is carefully designed, with a center thickness of 2.3mm and edge thickness of 3.01mm. The radii of the lens surfaces are R1=25.05mm, R2=-17.27mm, and R3=-49.33mm. The lens is a multiplet, meaning it is composed of multiple elements, and is circular in shape.
According to the vendor's website, the lens is currently in stock, making it readily available for immediate use. The lens' catalog number is 49-310-INK, and it can be found on the Edmund Optics website at https://www.edmundoptics.com/p/625mm-dia-x-40mm-fl-vis-nir-inked-achromatic-lens/9666/.
