fiber optical light source,handheld,Provides 1~5 wavelengths,measuring optical loss,Optical fiber sensors


OP-OPM21 optical power meter Is a handheld optical power meter, newly released in 2007, which can be used for absolute optical power measurements as well as for relative loss measurements in optic fiber networks. An Ø1.0mm photosensitive area photodiode is used to significantly improve the stability and the reliability. It features ingenious appearance, wide range of power measurement, high accuracy, user self-calibration function and reference power level storage.

Product Features:

  • Provides 1~5 wavelengths output which can be optional according to customers’ needs
  • CW, 2Hz modulation output at 650nm, and CW, 270Hz,1KHz,2KHz modulation output at other wavelengths.
  • High stability of the output power
  • Stable output wavelength
  • Backlight LCD display supports night operation
  • Low battery power indication
