This is a 50.0mm diameter, plano-convex lens with a focal length of 125.0mm, specifically designed for use with a wavelength of 1064nm. The 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 high Abbe number. The plano-convex shape, where one side is flat and the other is curved, is ideal for a variety of applications, particularly where a collimated beam is required.
The lens has a center thickness of 10mm and an edge thickness of 4.97mm, providing robustness and durability. The front and back surfaces of the lens are coated with Edmund Optics' Las V-Coat 1064, a specialized coating designed to enhance the lens' performance in laser applications.
The lens has an effective focal length (EFL) of 125.0mm, which is the distance from the lens to the point where the beam converges or diverges. The back focal length (BFL) is 118.39mm, which is the distance from the back surface of the lens to the point where the beam converges or diverges.
