Optics
Welcome to Thorlabs; below you will find links to optical components and systems, a subset of our entire line of photonics products. All single element optical components can be found under the optical elements link with the exception of optical components that have polarization properties since they have a separate link. Multi-element systems like beam expanders and objective lenses as well as interferometers, fiber collimators, reference cells, modulators, and other optical devices can be found by choosing the optical systems link. Thorlabs also manufactures an extensive line of free-space and fiber optic isolators; stock items ship the same day that they are ordered while our custom orders benefit from our streamlined design and manufacturing process, which minimizes lead time.

Thorlabs manufactures a wide selection of narrowband and broadband free-space optical isolators (Faraday isolators) that operate in spectral ranges from 365 nm to 9.80 µm, including high-power options, as well as fiber isolators designed for wavelength ranges from 650 to 2010 nm for polarization-independent versions and 770 nm to 2010 nm for polarization-dependent versions. For customers whose needs are not met by our stock selection, we offer a custom isolator service that can combine the best features across our entire isolator family. The Optical Isolator Selection Guide displays wavelength ranges and isolator types for all stocked isolators.
