The LA1399-A is a Plano-Convex lens, a type of spherical lens, sourced from Thorlabs, a renowned optical components manufacturer. This lens boasts a diameter of 2 inches, or 50.8 millimeters, and a focal length of 175 millimeters, making it suitable for a wide range of optical applications.
The lens is made from N-BK7, a popular glass type in the optical industry, known for its excellent optical properties and versatility. The Plano-Convex geometry, where one side is flat and the other is curved, allows for efficient light collection and focusing.
The LA1399-A features anti-reflection coatings on both the front and back surfaces, specifically designed for the ARC 350-700nm range. This coating enhances the lens's performance by reducing unwanted reflections and increasing transmission, thereby improving the overall efficiency of the optical system.
In terms of dimensions, the lens has a thickness of 3 millimeters at the edge and 6.7 millimeters at the center. The effective focal length (EFL) is 175 millimeters, and the radius of curvature (R1) is 90.1 millimeters. The back focal length (BFL) is 170 millimeters, and the lens has no inner or outer radius, indicating a uniform thickness across the lens.
