The 38-445 is a Plano-Convex lens, a type of spherical lens with a single curved surface and a flat surface. This lens, sourced from Edmund Optics, boasts a diameter of 12.0mm and a focal length of 25mm. The lens is made from the high-quality material n-BK7 Schott, ensuring excellent optical performance.
The lens features a front and back coating of EDM VIS-EXT, a coating specifically designed for use in the visible spectrum, between 350-700nm. This coating enhances the lens's transmission capabilities, making it ideal for applications that require high light transmission in the visible spectrum.
The lens has a thickness of 1.22mm at the edge and 2.7mm at the center, providing a solid and robust structure. The inner and outer radii of the lens are 0mm, indicating a flat inner surface and a curved outer surface. The effective focal length (EFL) of the lens is 25mm, and the back focal length (BFL) is 32.22mm.
