89-132 6mm Dia. x 18mm FL; VIS-EXT Coated; Double-Convex Lens VIS-EXT 350-700nm
The 89-132 is a double-convex lens with a diameter of 6mm and a focal length of 18mm, making it a compact and efficient optical component. This lens is sourced from Edmund Optics, a reputable vendor known for its high-quality optical elements. The lens is designed for use within the visible light spectrum, specifically between 350 and 700nm, making it suitable for a wide range of applications.
The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transmittance and low auto-fluorescence. This material ensures the lens delivers high-fidelity optical performance. The lens's geometry includes a center thickness of 2.2mm and an edge thickness of 1.7mm, providing a robust structure while maintaining a low profile.
The lens features a VIS-EXT coating on both the front and back surfaces. This coating enhances the lens's performance within the visible light spectrum, improving its transmission and reducing unwanted reflections. The inner and outer radii of the lens are 0, indicating a uniform curvature across the lens's surface.
