49-376-INK 30 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=150mm VIS-NIR 400-1000nm
The 49-376-INK is a high-quality achromatic doublet lens, designed and manufactured by Edmund Optics. This lens, with a diameter of 30 mm, is specifically engineered for use in the visible (VIS) and near-infrared (NIR) spectrum, spanning 400-1000nm.
The lens features a focal length of 150mm, indicated as EFL (Effective Focal Length), making it suitable for applications that require a longer focal length. The achromatic design of this doublet lens helps to minimize chromatic aberration, ensuring sharp and clear images across the entire spectral range.
The lens is composed of two types of glass, N-BK7 and N-SF5, both from Schott. The use of these high-quality materials ensures excellent optical performance and durability. The lens is coated with EDm VIS-NIR 0SP2002000 on both the front and back surfaces, enhancing its transmission capabilities in the specified spectral range.
The geometry of the lens includes an edge thickness of 8.88mm, an inner radius of 0mm, an outer radius of 0mm, and a center thickness of 8.1mm. The lens also features a central thickness 'a' of 2.6mm. The lens is circular in shape and is a multiplet, indicating that it is composed of multiple elements.
