Where to Buy Optical Spectrum Analyzers

CNI offers a wide range of products for spectrum analysis: fiber-optic spectrometers, multi-channel spectrometers, Raman/fluorescence probes, Raman spectrometers and others.

Quantifi Photonics' Optical Spectrum Analyzers offer cost-effective spectral test and measurement for the testing of optical sources, amplifiers, transceivers and passive optical components. Available as a compact benchtop or PXIe module with targeted wavelengths in O band, C band and L band and featuring built-in analysis including SMSR, OSNR and spectral width.

The grating-based HighFinesse/ Ångstrom’ spectrometers offer the capability for a very accurate simultaneous measurement of both wavelength and linewidth of laser sources. With a resolving power up to 40000 and a measurement speed up to 500 MHz, the product series covers the range from 192 nm to 11000 nm, allowing measurements of both pulsed and cw lasers. The grating based technology enables the analysis of laser sources over a large linewidth range. Connected to the PC via USB, after a simple software installation the spectrometers are ready for use.

Thorlabs manufactures optical spectrum analyzers that are compatible with fiber-coupled and free-space light sources. They 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. We offer two instrument types: the general-purpose OSA20xC instruments, which have a high update rate and moderate resolution, and the high-performance Redstone® OSA305 instrument, which has a high dynamic range and high resolution. Both types acquire the spectrum via Fourier transform, using a scanning Michelson interferometer. This approach enables not only a spectrometer mode but also a high-precision wavelength meter mode.

The ID OSA is an optical spectrum analyzer based on coherent detection principles. Designed for versatility and efficiency, it provides picometer-class spectral resolution across the C-band (1525 nm to 1565 nm) or the L-band (1565 nm to 1610 nm) and completes full-resolution scans in just 0.5 seconds. With two input ports of different sensitivity, it boosts the available power range to more than 90 dB, allowing for accurate analysis of both low power signals and high power DWDM bands. Its compact and sturdy design, without any moving parts, makes it the ideal instrument for both research in the lab and production testing.
