88-656 9.0mm Dia. x 27.0mm FL; VIS-EXT Coated Plano-Convex Lens VIS-EXT 350-700nm

The 88-656 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a 9.0mm diameter and a focal length of 27.0mm, making it a versatile choice for various 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 VIS-EXT coating on both the front and back surfaces. This coating is specifically designed to enhance transmission in the visible spectrum, between 350-700nm. The coating also provides protection against environmental factors, ensuring the lens maintains its performance over time.

The geometry of the lens is carefully crafted, with a thickness of 1.75mm at the edge and 2.5mm at the center. The radius of curvature (R1) is 13.95mm, and the back focal length (BFL) is 25.34mm. The lens's design and construction make it suitable for use in a wide range of optical systems.
