352220-C In Stock

The 352220-C by Thorlabs is a superior quality unmounted Geltech aspheric lens designed to enhance light collimation or focusing processes. This high-performance lens offers exceptional wavefront spherical aberration correction, ensuring optimal performance and precision in a variety of applications. The 352220-C lens is equipped with a broadband antireflection (AR) coating that operates effectively within the 1050 nm - 1620 nm range. The AR coating is deposited on both sides of the lens, providing superior transmission and preventing the loss of light due to reflection.

One of the standout features of the 352220-C lens is its ability to mitigate the effects of spherical aberration. This lens offers superior performance in applications that require laser diode and fiber output collimation, detector light imaging, spatial filtering, or light coupling of a fiber. Additionally, in applications where monochromatic sources are used, spherical aberration can often hinder the ability of a single spherical lens to achieve diffraction-limited performance when focusing or collimating light. The 352220-C lens is unmounted, which means that the flattest side with the greatest radius of curvature should face the laser diode or point source.
