88-678 12.0mm Dia. x 42.0mm FL; VIS-EXT Coated Plano-Convex Lens VIS-EXT 350-700nm
The 88-678 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a circular base shape with a diameter of 12.0mm and a focal length of 42.0mm. The lens's geometry is characterized by its edge thickness of 1.85mm and center thickness of 2.7mm. The effective focal length (EFL) is 42.0mm, and the back focal length (BFL) is 40.22mm.
The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. This material makes the lens suitable for a wide range of applications, particularly where high image quality is required.
The lens features VIS-EXT coating on both the front and back surfaces. This coating enhances the lens's performance in the visible spectrum, specifically between 350-700nm. The VIS-EXT coating reduces surface reflections, improving light transmission and enhancing the overall image quality.
