    Default Old SP-125 Laser Head

    Here's a bit of an update for this thread about this laser from about a year ago: http://www.photonlexicon.com/forums/...Power-Supplies

    I ended up going to Florida to pick up other old lasers and decided to buy the head that went with the oldest SP-250 power supply I've seen. The cover was cut into two parts, but the plasma tube is (like the power supply) the oldest oldest I've seen. It has the same glass bridge connecting the reservoir tank with the plasma tube that's only seen on the earliest of S-P lasers. Well worth the hauling, cleaning, and storage of another of these beasts for that feature alone.

    I love to see these old pictures Bob, keep posting 'em.

    There's something about HeNe's that i just love. Perhaps because they were the first lasers I ever owned, maybe it's the beautiful beam profile, or perhaps me using them to make my first ever holograms. I don't think this love affair is going to end anytime soon.

    My biggest regret was selling my green HeNe, i'd love to pick up another one of those... and perhaps a yellow, and an orange..............

    OK, I confess, i'm an addict
