88-645 6.0mm Dia. x 30.0mm FL; VIS-EXT Coated Plano-Convex Lens VIS-EXT 350-700nm
The 88-645 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 6mm, making it a compact yet powerful optical component. The lens's thickness at the edge is 1.01mm, while its center thickness measures 1.3mm, providing a balance between weight and optical performance.
The effective focal length (EFL) of this lens is 30mm, which is the distance from the lens's center to the focal point when the lens is imaging an object at infinity. The first radius of curvature (R1) is 15.5mm, and the back focal length (BFL) is 29.14mm, contributing to the lens's overall optical properties.
The lens is made from N-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. This makes the lens suitable for a wide range of applications, particularly those requiring high image quality and minimal chromatic aberration.
The lens features VIS-EXT coating on both the front and back surfaces. This coating is designed to extend the lens's usable wavelength range from 350nm to 700nm in the visible spectrum, enhancing its performance in various lighting conditions.
