The 49-353-INK is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a diameter of 25 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 is a multiplet, featuring a complex geometry that includes three radii of curvature (r1, r2, and r3) and multiple thicknesses (thickness edge, thickness center, and thickness center a). The effective focal length (EFL) of this lens is 35mm, making it suitable for a wide range of optical applications.
The lens is composed of two types of glass, S-BAH11 from Ohara and N-SF10 from Schott. Both these materials are known for their excellent optical properties, contributing to the high performance of the lens. The lens is further enhanced with a front and back coating of EDm VIS-NIR 0SP2002000, which provides superior anti-reflection properties across the VIS-NIR spectrum.
The lens is currently in stock and available for immediate purchase through the Edmund Optics website, as indicated by its weblink status. For more detailed information, including technical specifications and purchasing options, users are encouraged to visit the provided weblink.
