Thorlabs' Optical Spectrum Analyzers (OSAs) perform highly accurate spectral measurements. Compatible with fiber-coupled and free-space light sources, these 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. Our high-performance Redstone® series instruments have a high dynamic range and high resolution.

Our optical spectrum analyzers acquire the spectrum via Fourier transform, using a scanning Michelson interferometer. This approach enables a high-precision Wavelength Meter mode with seven significant figures and ±1 part-per-million (ppm) spectral precision, allows robust statistical analysis of the acquired spectra, and provides broadband spectral measurements with every scan. Each Redstone OSA includes a frequency-locked 1532.8323 nm reference laser, resulting in a spectral accuracy down to ±0.2 ppm.
