49-350-INK 20 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=40mm VIS-NIR 400-1000nm
The 49-350-INK is a high-quality achromatic doublet lens, designed and manufactured by Edmund Optics. This lens, with a catalog number 49-350-INK, is a multiplet type, featuring a base shape of a circle. It is specifically designed for use in the visible (VIS) and near-infrared (NIR) spectrum, with a wavelength range of 400-1000nm.
The lens has a diameter of 20mm and an effective focal length (EFL) of 40mm, making it a compact and powerful optical component. The edge thickness of the lens is 7.83mm, while the center thickness is 8mm, with an additional 2mm at the center a. The inner and outer radii are 0mm, indicating a symmetrical design.
The lens is made from two types of materials: N-BAF10 and N-SF10, both from Schott. These materials are known for their excellent optical properties, making them ideal for use in a wide range of applications. The lens is coated with EDm VISNIR0SP2002000 on both the front and back surfaces, enhancing its performance in the specified wavelength range.
