LB1901-C In Stock

The LB1901-C by ThorLabs is a top-of-the-line bi-convex lens crafted for superior performance in the 1050 nm - 1700 nm wavelength range. With an antireflection coating on both surfaces, this lens is optimized for a wide range of finite imaging applications.

The LB1901-C is fabricated from N-BK7, which is a commonly used material for optical components that are high in quality. This material is preferred when the additional benefits of UV fused silica are not necessary, making it an ideal choice for applications where cost-effectiveness is key. Designed with a focal length of 75.0 mm, the LB1901-C is best suited for use in situations where the image and the object are on opposite sides of the lens, and the ratio of the image and object distances is between 0.2 and 5. Additionally, the LB1901-C boasts an optical size of Ø1".
