89-012 20.0mm Dia. x 100.0mm FL; Plano-Convex Lens Laser V-Coat 633nm
The 89-012 is a Plano-Convex spherical lens, characterized by its circular base shape and a diameter of 20.0mm. This lens is designed with a long focal length of 100.0mm, making it suitable for applications that require a high degree of magnification or precision. The lens is fabricated from the high-quality material n-BK7 Schott, ensuring excellent optical performance and durability.
The lens features a significant thickness variation from the edge to the center, with a 3.32mm edge thickness and a 4.3mm center thickness. This variation contributes to the lens's ability to bend light effectively and maintain a high level of image quality. The lens's effective focal length (EFL) is 100.0mm, and its back focal length (BFL) is 97.13mm, providing a clear understanding of its optical properties for potential users.
The 89-012 lens is coated with Edmund Optics' Las V-Coat 633, a specialized coating designed for use with a 633nm wavelength. This coating enhances the lens's performance by reducing surface reflections and improving transmission, thereby increasing the overall efficiency and quality of the optical system in which it is used.
This lens is available from Edmund Optics and is currently in stock, making it an accessible option for those in need of a high-quality, Plano-Convex spherical lens for their optical systems.
