PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please sub

I use CRL UV604 and JB Superweld.
They both cure as clear/transparent.

I see JB superweld is based on a cyanoacrylate. How good is it on optics?

 

[RedCowboy]

It ( Superweld ) is not as strong of a bond as the CRL but it is easier to break free and even remove from optics with a strong thumbnail, so for temporary makeshift arrangements it's just right, but for a permanent build I use the CRL.

The CRL is strong and works well but it can have a very thin surface tack that fully cures after a day or so, I haven't noticed any out-gassing or optics contamination from it, but I have been wanting to try this one.

I deleted your comment for the reason provided. You do it a third time and you're getting a temp ban. Do not bring up old arguments. Original comment replied to also deleted. Keep it in the politics thread guys. Last warning for everyone

 

[Unown (WILD)]

Sorry. I haven't been able to find your reasoning. I only repeated it because the post I used to respond to was left up. If you could send me a PM showing me where I went wrong it would be helpful. Thanks.

I left the reason as a notification. If you cannot comprehend basic language then that's your problem. I don't want to hear any more of it.

Not an ebay find, but this is the only place in english i've found it mentioned. The only other source is a german conversation on google groups from 1999...

Recently got a Sowa Optronics Co. Ltd GLG 5414A laser power supply from E-waste (someone got to the laser first, unfortunately)

Any thoughts on where I would go to find more info/find people interested in it? Any idea how I might test it? seems like it puts out a very high voltage

Is this legit ? A bit low on WL for "yellow", but much closer than 532 right?

 

[CurtisOliver]

Laserland Australia were known to have sold lime green/yellow units. The wavelength will be legit. Whether they still suffer degradation is anyone’s guess. 560-570nm is often referred to as yellow by sellers despite the fact that it’s still green.

"degradation"? Do they burn out quickly? What was the issue?
