88-635 5.0mm Dia. x 25.0mm FL; VIS-EXT Coated Plano-Convex Lens VIS-EXT 350-700nm
The 88-635 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens has a base shape of a circle and a diameter of 5mm, making it compact and versatile for various applications. The lens's thickness at the edge is 1.36mm, while the center thickness is 1.6mm, providing a balanced structure for efficient light transmission.
The effective focal length (EFL) of this lens is 25mm, which is the distance from the lens's center to the principal focus, where light rays converge or diverge. The lens's front radius of curvature (R1) is 12.92mm, and the back focal length (BFL) is 23.95mm, contributing to its overall optical performance.
The lens is made of n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. This material ensures minimal chromatic aberration, making the lens suitable for a wide range of wavelengths, specifically 587.6nm.
The lens features VIS-EXT coating on both the front and back surfaces. This coating enhances the lens's transmission in the visible spectrum, typically 350-700nm, making it ideal for applications requiring high light transmission and clarity.
