Twin large frame HeNe lasers - Spectra Physics 127

Sadly, it should've been a trio but UPS broke one of them even though they were packed with tons of bubble wrap and foam.

From Sam's Laser FAQ - "The SP-127 used to be the flagship large-frame external mirror laser of the Spectra-Physics HeNe laser product line. With a spec'd output power of 25 or 35 mW (new ones did much more), their patented "Stabilite" resonator construction, and a hard-seal plasma tube, it was the laser of choice for holography and similar demanding applications."

These are the 35mW model - one is performing excellently and is outputting nearly 50mW of 632nm. The second one had some alignment issues but I've done some tweaking and have gotten the power up nearly in spec to 32-34mW.

I cannot wait.

Damn those are some nice HeNes! Nice find!! What's the tube voltage like on those things and how much did they cost?

They run on 6500vdc @ 11mA
