88-649 6.0mm Dia. x 72.0mm FL; VIS-EXT Coated Plano-Convex Lens VIS-EXT 350-700nm
The 88-649 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 6.0mm and a focal length of 72.0mm, making it a versatile option 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. This material ensures that the lens provides clear and precise optical performance.
The 88-649 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 reflection. The result is improved light transmission and increased contrast, which can be particularly beneficial in high-resolution imaging systems.
The lens has a thickness of 1.48mm at the edge and 1.6mm at the center. The inner radius is 0mm, and the outer radius is also 0mm, indicating a uniform curvature. The back focal length (BFL) is 70.97mm, and the effective focal length (EFL) is 72mm.
