If the time is 16 seconds or 14 seconds it will impact the accuracy of the reading.After the laser is turned off, the pointer on the dial will continue to move. The second is to use a container of water to cool the probe more quickly. 6 years ago 3.

One method is to wait for the pointer on the dial to return to zero. By using the laser power probe before and after the mirror, you can measure the power loss, and if it is significant then change out the optic for a new one. Most CO2 laser power meters are very expensive and are equipped with capabilities far beyond what the common laser machine operator/owner needs. The last recorded test measurement will be saved to the idle display screen next to LT For instance, my meter, after being calibrated, is rated for 19.6 seconds (mine is larger than the one being used here, and is based at 20 seconds). Measure maximum CO2 laser output power to certify purchased lasers perform per the warranty.
It may not be at zero because the room temperature has changed. Therefore, this test does not include the laser power measurement after the mirrors (which absorb a portion of the laser energy).To test if an optic is no longer functioning properly, place the probe in front of the optic to take a measurement. The adjustment is located on the back side of the stainless steel dial beside the word reset.The photograph shows the laser power meter directly in front of the laser. on so.... it's a simple thermometer with another scale :) on The 15 second exposure will be dependent on your meter.
Reply Use a screwdriver or wrench to adjust it. These instructions show a sub-$100 laser power meter probe at work, taking quick laser power measurements in less than a minute, with minimal setup time.Put on your laser safety glasses that are designed for the wavelength of your laser. The time is important, so use a stop watch, or some laser machines have a timer that can be used. Things to double check when you measure laser power A fairly common mistake we see is in regards to the wavelength correction factor, and how to use it at different wavelengths than 1064 nm. on Yes, but it is calibrated and scaled.
This is typically done in one of two ways. Measure maximum CO2 laser output power to certify purchased lasers perform per the warranty. Be careful not to permit the laser beam to reflect off of any of the stainless steel parts.Set the dial face pointer to the zero value. This can be done in the following manner:Turn on the laser for 15 seconds. This measurement value is the laser output power at the location of measurement.For more than one reading, such as when testing if a mirror has gone bad, cool the black body back to room temperature. The power meter is suitable for measuring C02 lasers from 10W to 200W of output power. Check your meter for a calibration sticker, which usually has the exposure duration listed on it. 5 years ago on At the point it stops, note the measurement. These meters capable of handling the energy deposit. 3. When you calculate the power loss, then you will know if there is a problem with the mirror.After you have decided the location for the laser measurement, then place the black body of the laser probe in the path of the unfocused laser beam. The subsequent measurement will be after the optic.
3 types of test are available 100W+ Suitable for lasers 100+ Watts in output power (15 second test) 50 – 100W Suitable for lasers 50 – 100 Watts in output power (30 second test) I believe it is actually called a thermopile with a bimetallic spring. Keep in mind that the detector has a NIST-traceable sensitivity value valid for a 1064 nm laser.
5 years ago Remember that a laser beam can easily be reflected so do not perform this test without safety glasses or goggles. By using the laser power probe before and after the mirror, you can measure the power loss, and if it is significant then change out the optic for a new one.
