This is a 4.0mm diameter x 6.0mm focal length Plano-Convex lens, sourced from the renowned optical components vendor, Edmund Optics. The lens is made from 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 350nm to 700nm. This coating enhances the lens's performance by reducing surface reflections and increasing transmission, making it suitable for a wide range of applications, particularly in the visible spectrum.
The lens's geometry includes a 1.53mm edge thickness and a 2.26mm center thickness, with a 3.11mm radius of curvature on the convex side. The back focal length is 4.51mm, and the effective focal length is 6mm. The lens's shape is spherical, and it has no inner or outer radius, indicating a uniform curvature across its surface.
