49-796 25.4 mm Dia. N-BAK1/N-SF15 Achromatic Doublet; EFL=101.6mm VIS-NIR 400-1000nm
The 49-796 is a high-quality achromatic doublet lens, designed and manufactured by Edmund Optics. This lens is specifically engineered for use in the visible (VIS) and near-infrared (NIR) spectrum, with a wavelength range of 400-1000nm. The lens is constructed from two types of glass, N-BAK1 and N-SF15, which are renowned for their excellent optical properties.
The lens has a diameter of 25.4mm and an effective focal length (EFL) of 101.6mm, making it suitable for a wide range of optical applications. The lens features a multilayer anti-reflection coating, denoted as 'edm visnir0sp2002000', which is applied to both the front and back surfaces. This coating enhances the lens's transmission efficiency and reduces unwanted reflections, thereby improving overall system performance.
The lens geometry is characterized by its edge thickness of 6.32mm, inner radius of 0mm, outer radius of 0mm, and center thickness of 5mm. The lens also features a central thickness 'a' of 3mm. The curvature of the lens surfaces is defined by three radii: r1=66.33mm, r2=-47.95mm, and r3=-178.05mm.
The lens is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website using the provided weblink.
