What could I do with this HeNe laser?

[142laser]

The Spectrals were made mostly for Raman Spectroscopy; an Italian HeNe laser! In the the old days MWK used to sell them in the USA for light show use also. They are rare now; I would hang onto it. It is high order multimode with random polarization; not good for holography. Phil, 142laser

Do you know what year it was made?

Do you know what year it was made?

I bought my Spectral HeNe tube it in 1995, but I think it was made about 1993-1994 (I can't remember well).
Anyway it is still fully working...
