69-317 6.0mm Dia. x 21.0mm FL; Plano-Convex Lens Laser V-Coat 405nm
The 69-317 is a Plano-Convex spherical lens, characterized by its 6.0mm diameter and 21.0mm focal length. This lens is sourced from Edmund Optics, a reputable vendor known for their high-quality optical elements. The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility.
The lens's geometry is defined by a 1.0mm edge thickness and a 1.42mm center thickness, providing a balanced structure for various applications. The lens's effective focal length (EFL) is 21.0mm, making it suitable for systems that require a moderate focal length. The front and back surfaces of the lens are coated with Edmund Optics' Las V-Coat 405, a specialized coating designed for 405nm wavelength applications, enhancing its performance in laser systems.
The lens's inner and outer radii are both 0mm, indicating a uniform curvature across the lens surface. This feature, combined with its Plano-Convex shape, makes it an ideal choice for focusing or collimating light in laser applications. The lens's circular base shape further adds to its versatility, allowing it to be used in a wide range of optical systems.
