Thanks. I will continue to read what's required for alignment, and see if I can source a hene laser... At this stage, if it only took me one whole day to get it aligned I'd be more than happy.

Yes, I know - I'm kicking myself as I tried to resist the urge to play with them in the first place, but caved in (that said, adjusting the mirrors did get me going initially, and it became clear that they were misaligned - the light levels I was getting prior to adjustment were very low). I...

The problem persisted, and now I have misaligned my mirrors :( I'm reading over Sam's pages on realignment. Unfortunately, I don't have the standby board and I haven't yet figured out how to measure the voltage drop.. I hope that I can realign things and get it up and working again, but I...

Yes, it does Red, but only above 50% power. Same for Blue pretty much.

Awesome.. Thanks for all the info.. Very relieved that I can continue to use this baby... I will read up more on how to monitor the voltage etc..

Model is 643R-LICA-A01 Note quite 10 years old.. It was attached to a confocal microscope, which is now collecting dust...

Also, what's the best safety googles to use with this laser? I've got yellow, green and red 'cheap' goggles, and an expensive pair of far-red goggles.. but none will do the job across all output lines.

Thanks UltimateK, After several episodes of trying, then stopping for a few hours, then trying again, I lastly tried a very slight adjustment of the bolts at the back of the laser (which I assume are part of the internal optics)... and the laser sparked and stayed lit... though it may just be a...

Hi all, I'm very new to lasers and this forum. I have an Omni 43 which was working for a while, but won't ignite any more :cryyy: . It was attached to an old confocal that wasn't being used, so I decided to put it to good use as part of a custom-microscope setup I have. It worked for a few...
