The 38-466 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens has a diameter of 15.0mm and a focal length of 25.0mm, making it suitable for a variety of optical applications. The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence.
The lens features a VIS-EXT coating on both the front and back surfaces. This coating, specific to the visual spectrum (350-700nm), is designed to enhance the lens's transmission capabilities and reduce surface reflections. The coating ensures that the lens delivers optimal performance in the visible light range, making it ideal for applications such as imaging, beam shaping, and laser systems.
The geometry of the lens includes a thickness of 1.4mm at the edge and 3.8mm at the center. The inner and outer radii are both 0mm, indicating a uniform curvature. The lens's effective focal length (EFL) is 25.0mm, and the back focal length (BFL) is 22.5mm. The radius of curvature (R1) is 12.92mm.
