69-526 6.0mm Dia. x 60.0mm FL; Plano-Convex Lens Laser V-Coat 980nm
The 69-526 is a Plano-Convex spherical lens, characterized by its 6.0mm diameter and 60.0mm focal length, specifically designed for use with a 980nm wavelength. This lens is sourced from Edmund Optics, a reputable vendor known for their high-quality optical components.
The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. It features a plano-convex geometry, where one side is flat (plano) and the other side is curved (convex). This design allows for efficient light collection and focusing.
The 69-526 lens has a center thickness of 58.95mm and an edge thickness of 1.45mm, providing a robust structure suitable for various applications. The lens's effective focal length (EFL) is 60mm, which is the distance from the lens's center to the focal point when the lens is imaging an object at infinity.
The lens is coated with Edmund Optics' Las V-Coat 980, a specialized coating designed for high laser damage threshold and high transmission at the 980nm wavelength. This coating ensures optimal performance and longevity of the lens in laser applications.
