49-323 12.5 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=25mm VIS-NIR 400-1000nm
The 49-323 is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens is specifically designed for use in the visible (VIS) and near-infrared (NIR) spectrum, spanning 400-1000nm. The lens boasts a 12.5mm diameter and an effective focal length (EFL) of 25mm, making it suitable for a wide range of optical applications.
The lens is composed of two elements: N-BAF10 and N-SF10, both from Schott. These materials are known for their excellent optical properties, contributing to the lens' high performance. The lens features a complex geometry, with radii of curvature of r1=17.27mm, r2=-10.99mm, and r3=-107.03mm. The edge thickness is 4.9mm, while the center thickness is 5mm, with an additional 1.25mm at the center a.
The lens is coated with a broadband anti-reflection coating, specifically the edm visnir0sp2002000 coating, on both the front and back surfaces. This coating is designed to reduce surface reflections and increase transmission, thereby enhancing the overall performance of the lens.
The lens is currently in stock and available for immediate purchase through the Edmund Optics website, as indicated by the "weblink status" field in the item data.
