49-335-INK 15 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=30mm VIS-NIR 400-1000nm
The 49-335-INK is a high-quality achromatic doublet lens, designed and manufactured by Edmund Optics. This lens, with a diameter of 15 mm and a focal length of 30 mm, is specifically engineered for use in the visible (VIS) and near-infrared (NIR) spectrum, spanning from 400 to 1000 nm.
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-resolution images with minimal chromatic aberration. The lens has a central thickness of 6 mm and an edge thickness of 5.88 mm, providing robustness and durability.
The 49-335-INK features a front and back coating of EDMM VisNIR0SP2002000, a proprietary coating developed by Edmund Optics. This coating enhances the lens's performance in the VIS-NIR spectrum, reducing surface reflections and improving light transmission.
The lens's geometry is characterized by its base shape, which is circular, and its radii (r1, r2, and r3), which are 20.72 mm, -13.17 mm, and -128.44 mm respectively. These parameters contribute to the lens's overall optical performance and field of view.
