49-333-INK 12.5 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=100mm VIS-NIR 400-1000nm
The 49-333-INK is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a diameter of 12.5 mm, is designed for use in the visible to near-infrared spectrum, spanning from 400 to 1000nm. The lens is specifically engineered to minimize chromatic aberration, ensuring clear, focused images across the entire spectrum of operation.
The lens features a focal length of 100mm, indicated by the EFL (Effective Focal Length) parameter. This makes it suitable for applications that require moderate magnification and a larger field of view. The lens is constructed from two types of glass, N-BK7 and N-SF5, both from Schott, ensuring high optical quality and durability.
The geometry of the lens is carefully crafted, with a central thickness of 3mm and edge thickness of 4.03mm. The lens surfaces are coated with EDm VIS-NIR 0SP2002000, a proprietary coating from Edmund Optics, designed to enhance transmission and reduce surface reflections in the visible to near-infrared spectrum.
The lens is available in a multiplet configuration, which is a combination of multiple individual lenses to achieve specific optical properties. This particular lens is a doublet, meaning it consists of two individual lenses. The curvature of the lenses is defined by the radii r1, r2, and r3, which are 61.54mm, -44.39mm, and -130.26mm respectively.
