38-439 6.0mm Dia. x 25mm FL; VIS-EXT Coated; Plano-Convex Lens VIS-EXT 350-700nm
This is a 6.0mm diameter, 25mm focal length plano-convex lens, sourced from Edmund Optics. The lens is made from n-BK7 Schott glass, a popular choice for its high refractive index and low dispersion. The plano-convex shape, where one side is flat and the other curved, is ideal for a variety of applications, including beam shaping and collimation.
The lens features VIS-EXT coatings on both the front and back surfaces. These coatings are designed to enhance transmission in the visible spectrum, specifically between 350 and 700nm. This makes the lens particularly suitable for applications that require high transmission in the visible range, such as imaging and laser systems.
The geometry of the lens includes a 1.1mm edge thickness and a 1.45mm center thickness. The inner and outer radii are both 0, indicating a sharp transition from the flat to the curved surface. The effective focal length (EFL) is 25mm, and the back focal length (BFL) is 24.04mm.
