Hey alaskan, 808nm emissions from my non-IR-filtered DPSS lasers seem to be reading around 803-805nm. So not too big of a difference, but you'll have to correct for it or set calibration points closer to 808 (mine were 473 and 633 - quite far away.)

He asked me to wait 3-4 weeks. Its now been
4 weeks and no tracking number or communication.:yabbmad:
I questioned again through ebay.

I ordered one as well and it took over 4 weeks
to get here. It seems like he builds them as ordered.
I opened it up to have a look inside...
Quality wise... it is slapped together. The slit mounting
slot was cut with a hacksaw while he was drunk or
having a Parkinson's Episode.
The Camera and grating are mounted with double back
tape and the slit is mounted with Scotch type magic
tape.
Now I know why it was so cheap.

That is unfortunate. The build quality apparently has much to aspire to. But given that these have an accuracy of 1nm I think I can forgive the build quality - it's still a better deal than anyone could have gotten before for that kind of precision. :beer:
There you go Mike...Lasersbee --
Thanks for the update. I may affix the "loose stuff"
with a few drops of UV cure glue.
He says that I'll have the tracking number tomorrow.
