49-344 18 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=60mm VIS-NIR 400-1000nm
The 49-344 is a high-quality achromatic doublet lens, boasting an 18 mm diameter and a focal length of 60mm, specifically designed for the visual (VIS) and near-infrared (NIR) spectrum, spanning 400-1000nm. This lens is sourced from the reputable optical vendor, Edmund Optics, and is available for purchase on their official website.
The lens is constructed from two types of Schott glass, N-BAF10 and N-SF10, which are renowned for their excellent optical properties. The front and back surfaces of the lens are coated with the EDM VIS-NIR 0SP2002000 coating, enhancing its performance in the specified wavelength range.
The lens geometry is intricately designed, with a central thickness of 3.85mm and edge thickness of 4.71mm. The first and second radii of curvature are 42.51mm and -26.24mm, respectively, while the third radius of curvature is -226.77mm. The lens does not have an inner or outer radius.
This lens is a multiplet, meaning it is composed of multiple optical elements. The multiplet design allows for superior optical performance, making it suitable for a wide range of applications in the VIS-NIR spectrum.
