49-380-INK 40 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=80mm VIS-NIR 400-1000nm
The 49-380-INK is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a diameter of 40 mm, is designed for use in the visible (VIS) and near-infrared (NIR) spectrum, specifically catering to the wavelength range of 400-1000nm.
The lens features a focal length (EFL) of 80mm, making it suitable for a wide range of optical applications. The lens is constructed from two types of Schott glass, N-BAF10 and N-SF10, which are renowned for their excellent optical properties.
The lens is coated with EDm VIS-NIR 0SP2002000, a proprietary coating developed by Edmund Optics, which enhances its performance in the VIS-NIR spectrum. The lens has a center thickness of 12.07mm and an edge thickness of 11.75mm, providing robustness and durability.
The lens is designed in the shape of a multiplet, which is a combination of multiple lenses, each with its own specific curvature and refractive index. This design helps to correct chromatic aberration, a common issue in optical systems, thereby improving the overall image quality.
The lens is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website provided in the item data.
