The LA1541-A is a high-quality plano-convex lens, manufactured by Thorlabs, a leading global supplier of photonics equipment. This lens boasts a diameter of 30.0 mm and a focal length of 200.0 mm, making it suitable for a wide range of optical applications.
The lens is crafted 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 LA1541-A features anti-reflection coatings on both the front and back surfaces, designed to minimize losses due to reflection across the 350-700 nm spectral range. This broadband coating enhances the lens's performance in various light conditions and applications.
The lens's geometry includes a thickness of 1.7 mm at the edge and 2.8 mm at the center, providing structural integrity and resistance to deformation. The inner and outer radii are 0 mm, indicating a sharp curvature on the convex side.
