1. Measuring range: 10MW ~ 50W. Note: when measuring laser power above 10W for a long time, it is necessary to add cooling block (air cooling or water cooling) to the probe. There are four m3 screw holes on the back of the probe to fix the additional cooling block

2 probe effective photosensitive aperture: 18mm

3 wavelength response range: 150nm-20um, no power calibration for wavelength

4. The minimum resolution of the meter display is 0.01W

5 the user can connect the meter to the computer, so that the laser power can be recorded in the hard disk of the computer, and the long-term power recording without time limit can be realized
