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.

40Gb/s DQPSK Receiver
The integrated DQPSK receiver incorporates an optical phase demodulator (delay-line interferometer or DLI) with 2 pairs of balanced photo-diodes and 2 linear TIAs into a single butterfly package. Compared with the currently available discrete solution in which a separate DLI and a separate receiver are used, the integrated DQPSK receiver eliminates labor intensive fiber routing and coupling (between the DLI and the balanced receiver) as well as the skew control. Moreover, the integrated DQPSK receiver offers a smaller footprint suitable for today’s demanding high speed transponder applications.

Turning Mirror
10769A
The 10769A is ideal for use in laser measurement and calibration applications. In the calibration of slant bed lathes, for example, the beam steering mirror deflects the beam from the laser head upward, through the interferometer, along the lathe's cross slide. One or more mirrors can also create a path from a laser head to an interferometer located in an otherwise inaccessible position, as in the case of a milling machine with a table that moves in only one axis.

Fourier Transform Optical Spectrum Analyzer, 600 - 1700 nm
OSA202C
Thorlabs' Optical Spectrum Analyzers (OSAs) perform highly accurate spectral measurements. Compatible with fiber-coupled and free-space light sources, these compact benchtop instruments suit a wide variety of applications, such as analyzing the spectrum of a telecom signal, resolving the Fabry-Perot modes of a gain chip, and identifying gas absorption lines. Many commonly available OSAs use grating-based monochromators, which have slow acquisition times due to the need to mechanically scan the grating and average out noise at each wavelength. Thorlabs' OSAs acquire the spectrum via a Fourier transform using a scanning Michelson interferometer in a push/pull configuration. This approach dramatically improves the acquisition time, enables a high-precision wavelength meter mode with 7 significant figures and ±1 part-per-million accuracy, and allows the included software to provide robust statistical analysis of the acquired spectra, as explained in the Design tab.

One Axis Differential Interferometer
10719A
The Keysight 10719A One Axis Differential Interferometer makes either a differential linear or angular measurement for use in single and multiple axis applications. The linear measurement gauges the displacement between two objects, such as a stage and an optical column or inspection tool. The 10719A also measures either pitch or roll. An angle is measured when both reference and measurement beams measure to the same mirror. The 10721A provides high immunity to unwanted interferometer displacement, such as thermal expansion. It is a modular, compact design with monolithic optics for maximized mechanical stability. Use of a small 3 mm beam helps decrease Abb offset error.
