The Optical Power Meter is a high accuracy optical power measurement tool. It tests dynamic range of optical power from +3 to –60dBm with six calibrated wavelengths: 850nm, 1300nm, 1310nm, 1490nm, 1550nm and 1625nm.

With Hobbes Optical Power Meter, it displays a pass or fail result according to the threshold the user has defined. It also has the capability to identify modulate signals (270Hz, 1kHz, 2kHz) simultaneously by the power source for identification purposes. For fast and easy operation in testing the corresponding wavelengths, we recommend the Hobbes optical light source (OPTIsource) as a complete instrument in auto–identifying wavelength of optical power source. 

It utilizes an InGaAs detector for an improved sensitivity and temperature stability. It also has the capacity to record up to 1000 test data that is up–loadable to a PC via USB connection for easy and convenient report purposes.
