Laser Assembly HeNe [633nm Legacy]

It powered up and held stable wavelength right out of the box—the 633nm output reads perfectly on our interferometer. Took about ten minutes to swap into my Verifire, and the beam path lined up with zero tweaking. Glad I grabbed this as a backup.

The alignment fit into my GPI system was seamless—no shimming needed. It’s noticeably brighter than the old unit, which cut my measurement noise in half.

The beam stability on this 633nm assembly is exactly what I needed for recalibrating our GPI system—alignment held steady through a full afternoon of testing. It dropped in without any shimming, which saved me a good chunk of time compared to the last retrofit I did.
