88-705 18.0mm Dia. x 27.0mm FL; VIS-EXT Coated Plano-Convex Lens VIS-EXT 350-700nm
The 88-705 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts an 18.0mm diameter and a focal length of 27.0mm, making it suitable for a wide range of optical applications. The lens is made from n-sf5 Schott, a high-quality optical material known for its excellent transmittance and durability.
The lens features a VIS-EXT coating on both the front and back surfaces. This coating is specifically designed to enhance the lens's performance in the visible spectrum, between 350 and 700nm. The coating reduces surface reflections, improving light transmission and enhancing the overall efficiency of the optical system.
The geometry of the lens is carefully crafted to ensure optimal performance. The edge thickness of the lens is 1.41mm, while the center thickness is 3.8mm. The lens's effective focal length (EFL) is 27mm, and the radius of curvature (R1) is 18.16mm. The back focal length (BFL) is 24.73mm, and the lens has no inner or outer radius, indicating a uniform curvature.
