2 . Maintenance of the Laser Oscillator
Inspecting the Laser Output
Measure and inspect the laser output before and after operation.
It is recommended that the installation space for the laser power meter is secured so
that the laser output from the output unit can be measured.
WARNING
Wear protective glasses . Shield the scattered light because it is also hazardous .
Item required
Laser power meter (FL500A-LP1 manufactured by Ophir is recommended) and pro-
tective glasses
CAUTION
Calibrate the laser power meter every year .
Operating Procedure
(1) Turn on the guide light and adjust the posi-
tion so that the beam diameter becomes
about 2/3 of the diameter at the light receiv-
ing part.
(2) Output the laser light and measure it.
If the output is low, clean or replace the protec-
tive glass of the output unit. For replacement,
refer to the operation manual for the output in
use.
Also check whether there is no change in mea-
surement environment such as ambient tem-
perature, cooling fan of the power meter, and
positional relationship between the output unit
and the power meter.
When the output is not restored, set the laser
output set value ("SET POWER”) again.
