89-134 6mm Dia. x 30mm FL; VIS-EXT Coated; Double-Convex Lens VIS-EXT 350-700nm
The 89-134 is a double-convex lens, characterized by its spherical shape and circular base. This lens, sourced from Edmund Optics, boasts a diameter of 6mm and a focal length of 30mm, making it a compact yet powerful optical component. The lens's geometry includes a 2mm edge thickness and a 2.3mm center thickness, contributing to its robust structure.
The lens's base shape is circular, and it features an effective focal length (EFL) of 30mm, which is the distance from the lens's center to the focal point. The first radius of curvature (R1) is 30.61mm, while the second radius (R2) is -30.61mm, indicating the lens's convex-convex design. The back focal length (BFL) is 29.23mm, which is the distance from the lens's rear focal point to its surface.
The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. This material is ideal for applications that require high image quality and minimal chromatic aberration.
The lens is coated with EDM VIS-EXT, a broadband anti-reflection coating designed for use in the visible spectrum, specifically between 350 and 700nm. This coating reduces surface reflections, enhancing the lens's light transmission capabilities and improving overall system performance.
