Where to Buy Wavemeters

Our sensitive and compact, HighFinesse/Ångstrom’ wavelength meters deliver high speed wavelength measurements of pulsed and continuous laser with absolute accuracy down to 2 MHz. A wide variety of models is available, covering wavelength ranges from 192 nm up to 11000 nm. Together with the photonic crystal switch technology only offered by HighFinesse, the wavemeters enable the quasi-simultaneous measurement of up to 8 channels over a broad wavelength range. Very robust and easy to use, HighFinesse wavemeters are a versatile and reliable tool for scientific research as well as industrial applications and optical technology.

As the pioneer in the optical frequency comb technology, Menlo Systems offers a full product line from the compact and fully automated SmartComb to the ultra-low noise Optical Frequency Comb FC1500-ULN^plus. Our patented figure 9^® mode locking technology ensures lowest phase noise and long-term reliable operation.

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 wavelength meters of the WS series accomplish wavelength measurements with highest accuracy. Both cw and pulsed lasers with narrow-band emission can be examined, monitored and even actively controlled. Various models of the WS series are available, covering UV to IR wavelength ranges (192 nm – 11 μm). Based on a rugged Fizeau interferometer setup without any moving components, the wavelength meters provide quasi unlimited lifetime. The spectrum analyzers LSA and HDSA allow for multi-line or broadband spectrum of light sources like cw and pulsed lasers, gas discharge lamps, superluminescence diodes, semiconductor laser diodes and LEDs.
