49-341-INK 18 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=35mm VIS-NIR 400-1000nm

The 49-341-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-resolution imaging.

The lens features an effective focal length (EFL) of 35mm, providing a moderate level of magnification suitable for a wide range of optical systems. The geometry of the lens includes a thickness of 5.61mm at the edge and 6.01mm at the center, with an additional center thickness 'a' of 1.6mm. The lens curvature is defined by radii of 24.26mm and -16.23mm for the first and second surfaces, respectively, and -152.99mm for the third surface.

The 49-341-INK is constructed from N-BAF10 and N-SF10 Schott glass, materials known for their excellent optical properties. The lens is coated with EDMM VISNIR0SP2002000 on both the front and back surfaces, enhancing its transmission capabilities across the VIS-NIR spectrum.
