49-344-INK 18 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=60mm VIS-NIR 400-1000nm
The 49-344-INK is an 18 mm diameter achromatic doublet lens, designed and manufactured by Edmund Optics. This lens is specifically engineered for use in the visible (VIS) and near-infrared (NIR) spectrum, with a wavelength range of 400-1000nm. The achromatic design ensures minimal chromatic aberration, making it an ideal choice for applications requiring high optical performance.
The lens features a focal length (EFL) of 60mm, providing a moderate magnification and field of view. The geometry of the lens includes a thickness of 4.71mm at the edge and 3.85mm at the center, with an inner radius of 0mm and an outer radius of 0mm. The lens is constructed from two types of Schott glass, N-BAF10 and N-SF10, which are renowned for their excellent optical properties.
The 49-344-INK 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 and reduces reflection, thereby improving its overall light efficiency.
