88-717-INK 20.0mm Dia. x 80.0mm FL; VIS-EXT; Inked; Plano-Convex Lens
The 88-717-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens has a diameter of 20.0mm and a focal length of 80.0mm, making it suitable for a wide range of optical applications. The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion.
The lens features a Visible Extended (VIS-EXT) coating on both the front and back surfaces. This coating enhances the lens's transmission in the visible spectrum, typically between 350-700nm. The coating also provides protection against environmental factors, ensuring the lens maintains its performance over time.
The geometry of the lens includes a thickness of 1.13mm at the edge and 2.35mm at the center. The inner and outer radii are 0mm, and the back focal length is 78.45mm. The lens's shape is spherical, with a radius of curvature of 41.48mm on the convex side.
