LK1431L1 In Stock

The ThorLabs LK1431L1 is a high-quality Plano-Concave cylindrical lens that is specifically designed for one-dimensional shaping of a light source. This lens is ideal for various applications where the shaping of light is required like the transformation of a collimated laser beam into a line generator. Cylindrical lens pairs can also be utilized to shape images anamorphically.

The LK1431L1 features a unique design that minimizes the introduction of aberration, making it an ideal choice for high-precision applications. When used to diverge a beam, the curved surface of the lens should face the source to ensure minimal aberration. One of the key features of the LK1431L1 is that it is uncoated, which means that the amount of light reflected from each surface of the lens is not reduced, unlike other cylindrical lenses that are AR coated. 

Additionally, the LK1431L1 is made of high-quality N-BK7 glass, which ensures excellent performance and durability. It has an uncoated wavelength range of 350 nm - 2.0 µm, which makes it ideal for a wide range of applications. The lens has a focal length of -75.00 mm and a focal length tolerance of ±1%, ensuring reliable and accurate performance in a wide range of applications.
