Hey guys,
Just a big +1 for Dave.... I purchased a Gree-Ne or green He-Ne laser plus PSU off him for a bargain in my books.
It took approx 2 weeks to get here, but Dave had it sent the next day after payment.
The laser is a 2.5mW green He-Ne with a 12V DC boost PSU. The PSU draws about 1.8A at 12V.
The outside of the box got damaged a bit in transit...
But that's ok, because it was so well wrapped inside nothing broke.
Once I put power to the PSU the current was active at 1mA, then in about 2-3 seconds jumped up to 1.5A then slowly climbed to 1.8A. I think this is a safety feature, because the laser turned straight on unlike my other He-Ne tube which sits there sparking for a while before lighting up.
Here is a "Beam shot"... I'll take a better one, once its dark here!
And I just love the beam profile... this was at about 7 meters away.
All in all, very pleased with Dave's communication and professionalism as I always am and would happily deal with him again! :thanks:
