*3: The number of flashes as an indication of the life of the lamp (lowering
of light quantity, cracks in the lamp, and a lighting failure) differs greatly
depending on the laser output conditions and the laser irradiation interval.
When the flashlamp is used in a single shot or with a long standby
time as compared with continuous flash in repetition of several shots to
several tens of shots per second, the number of flashes may become
one-tenth or less. This is why the normal pulse laser lamp flows a low
current after turned on and be ready to flash immediately, but when the
time of ready state where this low current ows is long, the tip of the lamp
electrode tends to be deteriorated earlier. Also, the lamp electrode is
deteriorated earlier when the lamp is used with nearly maximum output
energy. Therefore, the number of ashes may become one-tenth or less as
compared with continuous irradiation.
*4: When the laser is stopped for a long time (for about one month), the usable
period of the lithium battery is shortened.
*5: We do not specify a degree of parallelism of our standard protective
glass. Therefore, the condensing position may be shifted before and after
replacing the protective glass due to individual dierences. The protective
glass having a very small positional deviation is also available. Contact us
as needed.
*6: An expected life of the branch shutter is 5 million times. Switching ON
and OFF of the branch shutter according to the ON/OFF state of the laser
can lead to shortening the operation interval. The branch shutter can be
used for a longer time by setting it to ON at startup of the equipment and
keeping it ON during the laser operation in principle.
*7: An expected life of the timesharing unit is 1 million times. When the
timesharing unit is operated over the operation interval, the optical fiber
may be damaged by the optical axis deviation due to degradation in stop
accuracy of the timesharing unit. We recommend a periodic inspection.
*8: The optical fiber may be damaged if it is used when dust or oil mist is
attached on its end face.
