89-184 25mm Dia. x 175mm FL; VIS-EXT Coated; Double-Convex Lens VIS-EXT 350-700nm
This is a 25mm diameter, 175mm focal length double-convex lens, sourced from Edmund Optics. The lens is made from the high-quality material n-BK7 Schott, a borosilicate crown glass known for its excellent optical properties. The lens features a front and back coating of edm vis ext, a type of anti-reflective coating that enhances transmission in the visible spectrum (350-700nm).
The lens has a center thickness of 3.2mm and an edge thickness of 2.33mm, providing a robust structure. The front and back radii of the lens are 180.4mm and -180.4mm respectively, indicating a strongly converging lens. The back focal length is 173.94mm, and the effective focal length is the same as the specified focal length of 175mm.
This lens is suitable for a wide range of applications that require high-quality imaging in the visible spectrum, such as microscopy, beam shaping, and optical imaging systems. The anti-reflective coating ensures minimal loss of light due to reflection, enhancing the overall efficiency of the system.
