49-337 15 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=50mm VIS-NIR 400-1000nm
The 49-337 is a high-quality achromatic doublet lens, 15 mm in diameter, with an effective focal length (EFL) of 50mm. This lens is designed for use in the visible (VIS) and near-infrared (NIR) spectrum, specifically covering the range of 400-1000nm.
The lens is composed of two elements, made from N-BK7 and N-SF5 Schott glass, respectively. These materials are chosen for their excellent optical properties, contributing to the lens's high performance. The lens features a sophisticated geometry, with a thickness of 5.12mm at the edge and 5mm at the center. The inner and outer radii are 0, and the lens has a center thickness 'a' of 1.5mm.
The 49-337 lens is coated with Edmund Optics' VIS-NIR coating (edm visnir0sp2002000) on both the front and back surfaces. This coating enhances the lens's performance in the VIS-NIR spectrum, reducing reflection and increasing transmission.
The lens is sourced from Edmund Optics, a leading vendor in the optical industry, and is available for purchase through their website. The current status indicates that the lens is in stock, ensuring quick delivery for your optical system needs.
