High grade thermoelectric laser energy meter 1 range:10mW~50W,be careful:Long time measurement10WAbove laser power,It is critical so as to add a heat sink to the probe(Air cooled or water-cooled),There are four at the back of the probeM3The screw hole can repair the outside warm temperature sink 2 Effective photosensitive aperture of probe:18mm three Wavelength reaction range:150nm~20um,No power calibration for wavelength is required 4 The minimal decision of meter exhibit is:0 five The person can join the meter to the computer,Thus, the laser energy can be recorded within the laptop computer hard disk,Realize limitless long-time energy recording '
