Hi,

I'm trying to repair some old helium-neon lasers for a physics lab (155SL Uniphase and 155 spectra physics). Is it possible to find replacement tubes for these lasers?

Thanks,

Josh

Apparently I had one of those uniphase lasers. The tube was hard sealed,
but the thing died when it was dropped and the mirrors got knocked out of
alignment. I still have the transformer and probably the extruded case.

the thing was super super simple inside.
