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.

Fourier Transform Optical Spectrum Analyzer, 350 - 1100 nm
OSA201C
-
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.

Beam Directing and Reflecting Optics
-
Beam directing and reflecting optics simply reflect, bend or translate the beam, but do not typically modify the polarization, except for polarizing beam splitters. For example, mirrors, cube corners and retroreflectors are attached to objects that move in order to keep the weight down on the moving object (instead of mounting the interferometer on the moving object).
