William,
Do you have a good UPS system on your machine? We found that that
makes a big difference in laser life. We have had our lasers run in
excess of 3000 consistantly.

Eric,
Since 1991 I have seen lasers last anywhere from 50 to 3000 hrs. I have yet to
experience a laser making it past the 3000 hr barrier.
Melles or Omnichrome, I'd say pretty much the same. I have been told that my
power supply killed my last laser (800 hrs) ..... who knows, same power supply
and another laser now at 1900 hrs!

Dear List,
We have seen over the past couple of years, the HeCd lifetimes slowly
decreasing, over several different applications - other than SLA. They
used to run for 8-10 hours typically. Now we are currently seeing them
fade in power starting at 2-3,000 hours.
Can any of the SLA-250 users please help us help confirm,or deny this ?
It has seemed that ever since Melles aquired Liconix, and Omnichrome,
that quality has been placed lower on the priority list, than quantity.
Of the last 3 Omnichrome series 74 lasers that we have seen,
on the SLA-250's, they died at:
1,163 hours
253 hours
116 hours
These lasers came straight from the box. Shipped from Melles,
to our customer's site. (Which also took too many weeks !!)
Thank you for your help, & looking forward to all of your replies.
