Fiber End Face Interferometer
Thorlabs' GL16 End Face Interferometer measures and images the end face geometry of single- and multi-fiber connectors. A non-contact technique called scanning white-light interferometry (SWLI) provides high accuracy, repeatability, and reliability for fiber connector testing, particularly for pass/fail testing using IEC or Telcordia requirements. The system can be controlled locally through the touchscreen display or remotely through a browser-based application (see Software tab for details), allowing it to be easily integrated on the production floor.

Single Beam Interferometer
10705A
The Keysight 10705A Single Beam Interferometer, the smallest linear interferometer, is designed for making low mass or limited space single axis measurements. It is ideal for use in disk drive and other confined space applications. The single beam interferometer is called that because the outgoing and returning beams are superimposed on each other, giving the appearance of only one beam traveling between the interferometer and the retroreflector.

10G DPSK Demodulator
Optoplex’s Optical DPSK Demodulator, also known as Delay Line Interferometer (DLI), converts phase modulation to amplitude modulation over the entire C+L band in support of data transmission rates of 2.5,10 or 40 Gb/s. The DPSK demodulator is designed for phase modulated optical communication systemsutilized in commercial, defense and space exploration markets. The device plays a key role in improvingsignal quality and performance to meet the expanding demand for higher data rates and more complextransmission formats within current and next generation systems without major capital expenditure.Optoplex’s DPSK Demodulator is based on a patented free-space optical design, which is compact, athermal and polarization-independent. The measured frequency drift over temperature is only ~0.02 GHz/°C for our standard passive device. Further, this DPSK Demodulator exhibits a total polarization-dependent phase shift of less than 2 degrees over the entire operating temperature range with a high extinction ratio. Optoplex’s DPSK Demodulators can be configured to be fully tunable, colorless tunable or purely passive. Dual-Rate DPSK Demodulator is also available.

Plane Mirror Converter
10722A
The Keysight 10722A plane mirror converter modifies the use of the 10702A linear interferometer. With an additional 10703A reflector, the 10722A converts the 10702A into a 10706A plane mirror interferometer. With an additional 10723A high-stability adapter, the 10722A converts the 10702A into an 10706B high-stability plane mirror interferometer.

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.
