49-693 15mm Dia. UVFS Aspheric Lens; EFL=15mm; NA=0.5 UV 250-425nm
This is a 15mm diameter aspheric lens, catalog number 49-693, sourced from Edmund Optics. The lens is made of UVFS (Ultra-Violet Fused Silica) material, specifically syn hpfs7980 corning, and has a numerical aperture (NA) of 0.5. It is designed for use in the ultraviolet spectrum, specifically between 250 and 425nm.
The lens features a focal length (EFL) of 15mm and a clear aperture of 15mm. The edge thickness of the lens is 2.43mm, while the center thickness is 7.25mm. The front and back surfaces of the lens are coated with EDM UV 250-425nm coating, providing protection and enhancing its performance in the specified UV range.
The aspheric design of the lens helps to reduce spherical aberration, providing superior image quality. The lens geometry includes a inner radius of 0mm, an outer radius of 0mm, and a back focal length (BFL) of 10.029mm. The lens surface is defined by the conic constant k1 (-2.076598), with higher order aspheric terms (k2, k3, etc.) being zero.
The lens is currently in stock and available for purchase through the provided weblink.
