LJ1695L1 In Stock

The LJ1695L1 by ThorLabs is a high-quality plano-convex cylindrical lens designed to provide precise magnification in a single dimension for a wide range of applications. Fabricated from a durable N-BK7 glass substrate, this lens is uncoated and optimized for the wavelength range of 350 nm - 2.0 µm. One of the key features of the LJ1695L1 is that it can collimate and circularize a laser diode output, making it ideal for use in laser diode applications.

The LJ1695L1 is designed to act symmetrically on an incident ray in one dimension, which is similar to how spherical lenses operate in two dimensions. This symmetry makes this lens an excellent choice for anamorphic shaping of a beam, where a pair of cylindrical lenses can be used to provide precise collimation and circularization. Another potential application for the LJ1695L1 is to focus a diverging beam, with a single lens, onto a detector array. To decrease the development of spherical aberrations, it is recommended that when line focusing, light that is collimated should be incident on the curved surface. Similarly, light from a line source should be incident on the plano surface when collimating. These design considerations help to ensure optimal performance and minimize any potential aberrations. In addition to its advanced design features, the LJ1695L1 also boasts a focal length of 50.00 mm and a focal length tolerance of ±1%.
