48-292 25mm Dia. x 400mm FL UV-AR Coated; UV Plano-Convex Lens UV-AR 250-425nm
The 48-292 is a UV Plano-Convex Lens, 25mm in diameter and with a focal length of 400mm, offered by Edmund Optics. This lens is designed for use with ultraviolet light, specifically within the wavelength range of 250-425nm, making it ideal for applications such as UV curing, UV spectroscopy, and fluorescence microscopy.
The lens is made from fused silica (mal-1965), a material known for its high transmittance in the UV region, low autofluorescence, and excellent thermal shock resistance. The front and back surfaces of the lens are coated with the EDM UV STD CURVE anti-reflection coating, which is designed to reduce surface reflections and increase transmission in the UV range.
The lens geometry includes a center thickness of 2.44mm and an edge thickness of 2.01mm, providing a robust structure while maintaining a low profile. The inner and outer radii are 0mm, indicating a flat surface on the non-curved side of the lens. The lens has a base shape of a circle, making it suitable for a wide range of applications.
The item data also provides the effective focal length (EFL) of the lens, which is 400mm, and the back focal length (BFL) of 398.33mm. These specifications are crucial for accurate lens placement and focusing in the optical system.
