Wavelength Meters

HighFinesse laser measurement equipment

  • Unmatched absolute accuracy down to 2 MHz
  • Measurement ranges from UV to IR (192 nm .. 11 µm)
  • For pulsed and cw lasers
  • Sensitivity down to nW light power
  • Up to 600 Hz acquisition speed

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, super luminescence diodes, semiconductor laser diodes and LEDs.
