Confirm laser output (Daily inspection)
Confirm the laser output regularly in order to maintain consistent marking quality.
The laser output should be measured with a commercially available meter using the following steps:
1.
Prepare a commercially available power meter.
ワㄐㄕㄊㄆ
• Be sure to use the calibrated power meter.
• The power meter with the detector having the damage threshold (maximum average power density) of more than 10kW/cm
2
should be used.
• Also the size of the detector should be more than
φ
10 mm.
• A difference may arise under the high/low temperature. Measuring power with normal temperature (20 to 30 Celsius
degree) is recommended.
• Before measuring the laser power, make sure there is no contamination in the laser emission port. If the laser emission
port is contaminated or damaged, an error may result in the measurement of the laser power.
2.
Install the power meter.
Put the detector of the laser power meter vertically down from the center of the laser emission port and place it at the
following distance, i.e. one-third to half of the specified work distance of the laser marker.
