mmm about 120 sold so far .... could take a long while to get to 500 .... might be worth getting a back up price for 200/300

In the beginning there was none. Then came the light - #1 UKLEM - 2007

15 for me please.
Ok we're heading in the right direction numbers wise, I have more interest than shown in this thread and I have talked the manufacturer into a smaller qty too so am getting the trigger finger warmed up and ready to pull
To answer some questions:
I have been told 2MW/CM squared damage threshold @ 532nm (note, capital M) - sounds a lot to me but wtf do I know
Reflective performance drops off to about 93% at 60 degrees AOI, but without any data from other galvo mirrors I'm not sure if this is good or bad..
They can do galvo mirrors of 6x11x.8 or 7x12x.8 with small corner chamfers and the same mirror coating, these will be about £10 per set
Wouldnt 2 mega watts vaporise the mirror?
Thanks Simon thats brilliant!
I will probably take eight of the thin (7 x 12 x 0.8mm) ones as well as ten of the others. (would have preferred 8 x 13 x 0.8)
How does reflection drop off in the other direction eg. 120 degrees ?
What colour and polarization compared to the angle is the 93%@60degrees drop off?
Cheers

I'll take 2 sets of both sizes of galvo mirrors.
Yay!
I wish I was equipped to test that theoryOriginally Posted by QUAZAR;
It does sound high to me and I have asked the manu to check and let me know, even specifically high power YAG mirrors were only (only.. meh) about 1.5MW/cm IIRC
At 120 degrees won't the beam then be on the back of the mirror - and the galvo shaft in 2 or more pieces?Originally Posted by catalanjo;
I asked about the losses at 60 degrees AOI because it equates to scanning at the outer edge of 30 degrees full angle scanning, I think?
In any event this information is about as much use as a coal powered frog violin in the absence of any other meaningful data to compare it with
We will be in for say 50, if they can handle lots of photons
