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.

Optical Spectrum Analyzer
an optical spectrum analyzer for analyzing short wavelengths from 350nm to 1000 nm. Because it adopts a Fourier spectrum system with a Michelson interferometer, the 8341 can measure the coherence. With its narrow wavelength resolution of 0.01nm * , the 8341 is very effective for the evaluation of not only CD/DVD laser diodes, but also for blue-violet laser diodes. In addition, the built-in He-Ne laser acts as a wavelength reference to ensure a high wavelength measurement accuracy of ±0.01nm * . Finally, with its fast 0.5s * measurement speed, the 8341 is ideal for building into systems for mass production and evaluating temperature characteristics of system components.

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).
