88-654 9.0mm Dia. x 18.0mm FL; VIS-EXT Coated Plano-Convex Lens VIS-EXT 350-700nm
The 88-654 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 18.0mm, 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 designed to extend the visible range of the lens, making it suitable for use in wavelengths between 350-700nm. The coating also helps to reduce surface reflections, improving the overall transmission of light through the lens.
The geometry of the lens includes a thickness of 1.25mm at the edge and 2.41mm at the center. The lens's effective focal length (EFL) is 18mm, and its back focal length (BFL) is 16.41mm. The lens's inner and outer radii are both 0mm, indicating a flat surface on the uncoated side.
