The 88-653 is a plano-convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a 9.0mm diameter and a 15.0mm focal length (FL), making it suitable for a variety 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 VIS-EXT coating on both the front and back surfaces. This coating, specifically designed for the visible spectrum (350-700nm), enhances the lens's transmission and reduces surface reflections. The edge thickness of the lens is 1.56mm, while the center thickness is 3mm, providing a robust structure for its size.
The lens's geometry includes an inner radius of 0mm and an outer radius of 0mm, indicating a uniform curvature across the lens surface. The effective focal length (EFL) is 15mm, and the back focal length (BFL) is 13.02mm. The radius of curvature (R1) is 7.75mm.
