49-792-INK 25.4 mm Dia. N-SSK8/N-SF56 Achromatic Doublet; EFL=50.8mm VIS-NIR 400-1000nm
The 49-792-INK is a high-quality achromatic doublet lens, designed and manufactured by Edmund Optics. This lens, with a diameter of 25.4 mm, is specifically engineered for use in the visible (VIS) and near-infrared (NIR) spectrum, spanning from 400 to 1000 nm. The lens is constructed from two types of Schott glass, N-SSK8 and N-SF56, which are renowned for their optical clarity and durability.
The lens features an effective focal length (EFL) of 50.8 mm, providing a compact and efficient optical solution for various applications. The lens's geometry is meticulously designed, with an edge thickness of 8.2 mm and a center thickness of 8 mm, ensuring optimal light transmission and minimal distortion. The inner and outer radii are 0, indicating a symmetrical design that further enhances optical performance.
The 49-792-INK lens is coated with Edmund Optics' proprietary VIS-NIR coating (edm visnir0sp2002000) on both the front and back surfaces. This coating is specifically designed to enhance the lens's performance in the VIS-NIR spectrum, reducing surface reflections and improving light transmission.
