69-474 9.0mm Dia. x 22.0mm FL; Plano-Convex Lens Laser V-Coat 785nm
The 69-474 is a Plano-Convex spherical lens, characterized by its 9.0mm diameter and 22.0mm focal length, specifically designed for use with a 785nm 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), which is ideal for collimating or focusing light.
The 69-474 lens has a center thickness of 1.93mm and an edge thickness of 1mm, providing a robust structure while maintaining a low profile. The lens's effective focal length (EFL) is 22mm, which is the distance from the lens's principal point to the focal point when the lens is imaging an object at infinity.
The lens is coated with Edmund Optics' Las V-Coat 785, a specialized coating designed to enhance laser performance at the 785nm wavelength. This coating ensures high transmission, low reflection, and improved laser damage threshold, making it ideal for laser applications.
