88-716 20.0mm Dia. x 70.0mm FL; VIS-EXT Coated Plano-Convex Lens VIS-EXT 350-700nm
This product is a Plano-Convex lens, sourced from the reputable optical vendor, Edmund Optics. The lens boasts a diameter of 20.0mm and a focal length of 70.0mm, making it a versatile choice for various optical applications.
The lens is crafted from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. This material ensures the lens delivers sharp and clear images, free from chromatic aberration.
The lens features a VIS-EXT coating on both the front and back surfaces. This coating enhances the lens's performance in the visible spectrum, specifically between 350-700nm. It improves the lens's transmission, reduces surface reflections, and increases overall light throughput, making it an ideal choice for applications that require high light transmission and clarity.
The lens's geometry is another notable feature. It has an edge thickness of 1.59mm and a center thickness of 3.0mm. The inner and outer radii are 0mm, and the lens's effective focal length (EFL) is 70.0mm. The radius of curvature (R1) is 36.18mm, and the back focal length (BFL) is 68.03mm. These specifications contribute to the lens's high-performance capabilities.
