88-680 12.0mm Dia. x 54.0mm FL; VIS-EXT Coated Plano-Convex Lens VIS-EXT 350-700nm
The 88-680 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. It boasts a circular base shape with a diameter of 12.0mm and a thickness of 2.35mm at the edge, transitioning to 3.0mm at the center. The effective focal length (EFL) of this lens is 54.0mm, making it suitable for a variety of optical applications.
The lens is made from n-BK7 Schott, a high-quality optical glass, and features VIS-EXT coatings on both the front and back surfaces. These coatings are designed to enhance the lens' performance within the visible spectrum, specifically between 350-700nm. This makes the 88-680 an excellent choice for applications that require high transmission and clarity within this wavelength range.
The lens' geometry includes an inner radius of 0mm and an outer radius of 0mm, further emphasizing its Plano-Convex design. The back focal length (BFL) is 52.02mm, a critical specification for determining the lens' placement within an optical system.
