49-394 50 mm Dia. N-BAK4/N-SF10 Achromatic Doublet; EFL=300mm VIS-NIR 400-1000nm

The 49-394 is a high-quality achromatic doublet lens, boasting a 50 mm diameter and a focal length of 300 mm, specifically designed for the visual and near-infrared spectrum (VIS-NIR) range of 400-1000 nm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is available for purchase on their official website.

The lens is constructed from two types of Schott glass, N-BAK4 and N-SF10, which are renowned for their excellent optical properties. The front and back surfaces of the lens are coated with the advanced EDMM VISNIR0SP2002000 coating, enhancing its performance in the VIS-NIR spectrum.

The lens geometry is meticulously designed, with an inner radius of 0 and an outer radius of 0, ensuring optimal light transmission. The thickness at the edge of the lens is 10.24 mm, while the center thickness is 9 mm, and the center thickness 'a' is 3.5 mm. The lens's base shape is circular, and it is classified as a multiplet due to its construction from multiple optical elements.
