6.0mm Dia. x 20mm FL Plano-Convex Lens with VIS-EXT Coating for 350-700nm Wavelength
This item is a 6.0mm diameter x 20mm focal length plano-convex lens, sourced from the renowned optical components vendor, Edmund Optics. The lens is made of the high-quality material n-BK7 Schott, ensuring excellent optical performance. The lens features a plano-convex geometry, which is characterized by having one flat surface and one curved surface. This particular lens has a curvature radius (R1) of 10.34mm and a back focal length (BFL) of 19.04mm.
The lens is coated with the VIS-EXT coating on both the front and back surfaces. This coating is specifically designed to enhance the lens's performance in the visible spectrum, extending from 350nm to 700nm. The coating reduces reflection and increases transmission, thereby improving the overall efficiency and quality of the optical system in which the lens is used.
The lens has a thickness of 1.01mm at the edge and 1.45mm at the center, providing a good balance between compactness and optical power. The effective focal length (EFL) of the lens is 20mm, which is the distance from the lens's principal point to the focal point.
