The 88-651-INK is a Plano-Convex lens with a diameter of 9.0mm and a focal length of 12.0mm. This lens is sourced from Edmund Optics, a reputable vendor known for its high-quality optical elements. The lens is made from n-sf11 Schott, a material with well-established optical properties, ensuring reliable performance.
The lens features a Visible Extended (VIS-EXT) coating on both the front and back surfaces. This coating enhances the lens's performance in the visible spectrum, specifically between 350-700nm. The coating is designed to reduce surface reflections, improve transmission, and increase overall optical efficiency.
The geometry of the lens is carefully designed with a thickness of 1.36mm at the edge and 2.5mm at the center. The lens's inner and outer radii are 0mm, and the back focal length is 10.6mm. The lens's shape is spherical, a common choice for its simplicity and versatility.
