Review THORLABS La1213-a12.7 50.0 Coated Plano Convex Lens New In Box

The Thorlabs LA1213-A is a high-quality plano-convex lens with a 12.7 mm focal length and a 50.0 mm diameter. This lens is made of N-BK7 glass, which is a type of borosilicate glass known for its excellent optical properties, including low thermal expansion and good transmission in the visible and near-infrared regions.

The surface of the lens is coated with multiple layers of anti-reflection coating. These coatings reduce reflections from the lens surfaces, increasing the amount of light that can pass through the lens and improving the overall efficiency and contrast of optical systems. The coating also helps to protect the lens from scratches and other damage.

The plano-convex shape of the lens means that one side is flat and the other side is curved. This design is commonly used for collimating or focusing light in various applications, such as beam shaping, imaging, or spectroscopy. The large 50.0 mm diameter allows for a wide field of view, making this lens suitable for use in larger optical systems.

The LA1213-A lens is housed in a protective box, which provides additional protection during transportation and storage. The box is made of high-quality materials and features a secure closing mechanism to prevent the lens from being damaged during shipping or handling.

In summary, the Thorlabs LA1213-A is a high-performance plano-convex lens with a 12.7 mm focal length, 50.0 mm diameter, and N-BK7 glass construction. It is coated with multiple layers of anti-reflection coating for improved efficiency and protection. The lens comes with a protective box for safe storage and transportation. This versatile lens is an excellent choice for various applications in optical systems where high-quality collimation or focusing is required.
