89-162 15mm Dia. x 45mm FL; VIS-EXT Coated; Double-Convex Lens VIS-EXT 350-700nm
This is a 15mm diameter, 45mm focal length double-convex lens, offered by the renowned optical vendor, Edmund Optics. The lens is made of the high-quality material n-BK7 Schott, which is known for its excellent optical properties and durability.
The lens features a VIS-EXT coating on both the front and back surfaces, which extends its usable wavelength range from 350 to 700nm. This coating enhances the lens's light transmission capabilities and reduces surface reflections, making it suitable for a wide range of applications, including imaging and laser systems.
The lens's geometry includes a center thickness of 3mm and an edge thickness of 1.77mm, providing a balance between optical performance and mechanical strength. The lens's effective focal length (EFL) is 45mm, and its back focal length (BFL) is 44mm. The radii of curvature for the front and back surfaces are 45.99mm and -45.99mm, respectively.
