High-resolution high-rate laser spectrum analyser

ZOOM Spectra

Resolution Spectra

ZOOM Spectra is a High-Resolution High-Rate Laser Spectrum Analyser. It gives access to high spectral resolution on a simultaneous bandwidth of a few nanometers. ZOOM Spectra is both a multi-wavelength meter (picometer accuracy) and a spectrum analyser. It is the ideal tool for the characterisation of your CW and pulsed lasers.

  • Simultaneous bandwidth of a few nm
  • High measurement rate capability: 30 kHz
  • Compact size
  • Robust life-long factory calibration
  • User-friendly SpectraResolver software
  • Trigger



  • Continuous and pulsed/triggered lasers (ns/ps lasers)
  • Absolute wavelength and spectrum measurement
  • Multifrequency lasers
  • Mode-hop characterisation
  • Laser modulation
