The OptoTest OP735 Benchtop Optical Power Meter provides you with highly accurate measurement for optical power.  Below are highlights that show our differences:

  • Compact, benchtop standalone configuration
  • Up to 4 Channels that measure power simultaneously
  • Choose detectors to suit your needs, InGaAs, Silicon, High-Power, 1mm, 3mm, 5mm, 10mm.
  • Choose from standard SMF, FTTX, MMF wavelengths or your custom wavelengths
  • Choose from industry standard front panel connectors, including FC, ST, SC, LC, etc.
  • Optional Remote Detector and Integrating Sphere for added flexibility and expansion.


  • Up to 4 channels of individual optical power meters
  • Broad wavelength spectrum
  • InGaAs: 830nm to 1700nm
  • Silicon: 400nm to 1100nm
  • Measurement range
  • InGaAs: +6dBm to -72dBm
  • Silicon: +3dBm to -65dBm
  • Relative accuracy of 0.02dB
  • Measurement display resolution down to 0.001dB
  • Variable sampling rate via OPL-7 and custom DLL program
  • Can be controlled remotely via USB
