88-721 25.0mm Dia. x 30.0mm FL; VIS-EXT Coated Plano-Convex Lens VIS-EXT 350-700nm
The 88-721 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens has a base shape of a circle and a diameter of 25.0mm, making it suitable for a wide range of optical applications. The lens has a thickness of 1.73mm at the edge and 8.06mm at the center, providing a robust structure for precise optical work.
The effective focal length (EFL) of this lens is 30.0mm, which is the distance from the lens's center to the principal focus, a key factor in determining the lens's magnification power. The back focal length (BFL) is 24.69mm, which is the distance from the lens's rear surface to its principal focus.
The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. This makes the lens ideal for use in applications where high image quality and low distortion are required.
The lens features VIS-EXT coating on both the front and back surfaces. This coating enhances the lens's transmission in the visible spectrum, specifically between 350-700nm, making it suitable for use in a wide range of applications, including imaging, beam shaping, and laser applications.
