67-975 25mm Dia. x 75mm FL; Laser Grade Plano-Convex Lens Laser V-Coat 1064nm
The 67-975 is a laser grade plano-convex lens, boasting a diameter of 25mm and a focal length of 75mm, specifically designed for use with a 1064nm wavelength. This lens, sourced from the reputable vendor Edmund Optics, is a high-quality, reliable option for your optical needs.
The lens is made from fused silica, a material with the material ID 'fused sil mal-1965'. This material is known for its excellent transmission properties, making it an ideal choice for laser applications. The lens features a plano-convex geometry, meaning one side is flat (plano) and the other is curved (convex). This design allows for efficient light collection and focusing.
The 67-975 has a center thickness of 4.43mm and an edge thickness of 2.08mm, providing a robust and durable structure. The lens's effective focal length (EFL) is 75mm, and its radius of curvature (R1) is 34.39mm. The back focal length (BFL) is 71.96mm, and both the inner and outer radii are 0mm.
The lens is coated with Edmund Optics' Laser V-Coat 1064, a specialized coating that enhances its performance in laser applications. This coating is applied to both the front and back surfaces of the lens, ensuring optimal performance and longevity.
