LA1725-C N-BK7 Plano-Convex Lens; Dia:2 in; f=400.0 mm ARC 1050-1700nm
The LA1725-C 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 400 millimeters, making it suitable for a wide range of optical applications.
The lens is made from N-BK7, a high-quality borosilicate glass commonly used in optical systems due to its excellent optical properties. The Plano-Convex geometry, where one side is flat and the other is curved, allows for efficient light collection and focusing.
The LA1725-C features an Anti-Reflection (AR) coating, specifically designed for the wavelength range of 1050 to 1700 nanometers. This coating reduces surface reflections, thereby improving transmission and enhancing the overall performance of the lens.
The lens has a thickness of 3 millimeters at the edge and 4.6 millimeters at the center, providing structural rigidity while minimizing optical aberrations. The inner and outer radii are 0, indicating a sharp curvature on the convex side.
