49-372-INK 30 mm Dia. N-SSK8/N-SF10 Achromatic Doublet; EFL=60mm VIS-NIR 400-1000nm
The 49-372-INK is a high-quality achromatic doublet lens, designed and manufactured by Edmund Optics. This lens, with a 30 mm diameter, is specifically engineered for use in the visible (VIS) and near-infrared (NIR) spectrum, spanning 400 to 1000 nanometers.
The lens is constructed from two types of Schott glass, N-SSK8 and N-SF10, which are renowned for their excellent optical properties. The use of these materials ensures high-resolution images with minimal chromatic aberration. The lens has an effective focal length (EFL) of 60 mm, making it suitable for a wide range of optical applications.
The 49-372-INK features a sophisticated geometry, with a thickness of 7.66 mm at the edge and 8.47 mm at the center. The lens's inner and outer radii are 0, and it has a central thickness 'a' of 2.99 mm. This geometry is designed to optimize the lens's performance and durability.
The lens is coated with Edmund Optics' proprietary VIS-NIR coating (edm visnir0sp2002000) on both the front and back surfaces. This coating enhances the lens's transmission capabilities in the VIS-NIR spectrum, further improving its performance in a wide range of applications.
