49-352 25 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=30mm VIS-NIR 400-1000nm
The 49-352 is a high-quality achromatic doublet lens, designed and manufactured by Edmund Optics. This lens, with a 25 mm diameter, is specifically engineered for use in the visible (VIS) and near-infrared (NIR) spectrum, spanning 400-1000nm.
The lens is constructed from two types of Schott glass, N-BAF10 and N-SF10, which are renowned for their excellent optical properties. The use of these materials ensures high image quality, low chromatic aberration, and high transmission across the specified wavelength range.
The lens features an effective focal length (EFL) of 30mm, providing a moderate magnification suitable for a wide range of applications. The lens geometry includes a center thickness of 11.04mm and an edge thickness of 9.3mm, contributing to its robustness and durability.
The 49-352 is coated with Edmund Optics' VIS-NIR coating (edm visnir0sp2002000), which is applied to both the front and back surfaces. This coating enhances the lens's performance by reducing surface reflections, increasing transmission, and providing protection against environmental factors.
