89-125 5mm Dia. x 10mm FL; VIS-EXT Coated; Double-Convex Lens VIS-EXT 350-700nm
This is a high-quality double-convex lens, sourced from the renowned optical components vendor, Edmund Optics. The lens, identified as the 89-125 model, boasts a 5mm diameter and a 10mm focal length, making it a versatile choice for various optical applications.
The lens is crafted from the esteemed N-BK7 Schott material, a borosilicate glass known for its excellent optical properties, including low dispersion and high homogeneity. This material ensures the lens delivers sharp, clear images with minimal distortion.
The lens features a double-convex geometry, with radii of curvature of 9.98mm for both the front and back surfaces. This shape provides a wide field of view and a high numerical aperture, enhancing the lens's light-gathering capabilities. The lens's edge thickness is 1.36mm, while the center thickness is 2mm, contributing to its robustness and durability.
The lens is coated with the VIS-EXT coating on both the front and back surfaces. This coating, designed for the visible spectrum (350-700nm), enhances the lens's transmission capabilities and reduces surface reflections, thereby increasing the overall system's efficiency.
