LJ4426 In Stock

The LJ4426 by ThorLabs is a high-quality UV grade fused silica (UVFS) plano-convex cylindrical lens that is designed to meet the needs of a wide range of laser applications. The LJ4426 lens boasts an impressive uncoated wavelength range of 185 nm - 2.1 µm, making it the ideal choice for applications from the UV to the near IR.

One of the key features of the LJ4426 is its ability to collimate and circularize the output of a laser diode. This is thanks to its positive focal length of 25.0, which is perfect for applications that in which one dimensional magnification is required. Additionally, this lens is optimized for anamorphic beam shaping, light coupling into a slit, and 1D image compression applications. The LJ4426 UVFS coating is another standout feature of this lens. Not only does it offer high transmission in the deep UV, but it also exhibits almost no fluorescence that is laser-induced.

When it comes to its design, the LJ4426 lens is cylindrical, which means it acts symmetrically in one dimension on an incident ray. This makes it an ideal choice for a wide range of applications. For instance, a pair of cylindrical lenses can be used to provide anamorphic shaping of a beam. Alternatively, a single LJ4426 lens can be used to focus a diverging beam onto a detector array. To ensure optimal performance, it's essential to note that incident on the curved surface should be a collimated light source when focusing into a line. On the other hand, in order to form a collimated line, a line source should be incident on the plano source.
