The LA1380-C is a Plano-Convex lens, part of Thorlabs' extensive catalog of optical elements. This lens boasts a diameter of 2 inches and a focal length of 500.0 mm, making it suitable for a wide range of applications. The lens is made of N-BK7, a popular glass type in the optical industry, known for its excellent optical properties and versatility.
The lens's geometry is characterized by a thickness of 3 mm at the edge and 4.3 mm at the center. The effective focal length (EFL) is 500 mm, and the radius of curvature (ROC) is 257.5 mm. The back focal length (BFL) is 495.5 mm, and both the inner and outer radii are 0 mm.
The LA1380-C is coated with Thorlabs' proprietary coating, ARC 1050-1700nm, which is designed to enhance the lens's performance in the specified wavelength range. This coating reduces reflection and increases transmission, thereby improving the overall efficiency of the optical system.
The lens's shape is spherical, a common feature in many optical systems due to its ease of manufacturing and good optical performance. The lens is currently in stock, as indicated by the "weblink status" field in the item data.
