Do you know if it has the same outer dimensions as the 31-2772-000 and 31-2090-000? Also, single line or multiline?

It is single line and as for dimensions I'm not familiar with the dimensions of the others.

I believe these are 18" heads IIRC... 2600VDC @ 6.5mA and all of them are single line by intention. multiline HeNes are rare, as they're usually discarded at the factory as they're considered an 'oops' in manufacturing.

Thank you for the reply. Sorry I'm in the middle of getting stuff ready my girlfriend moves here in a couple weeks. 18" does sound about right it is a fairly long tube

Can't see the model number in the picture, but if it's the one in my sig, then it's the same one. Though mine I think is a bit more lively. There's a polarized version too though I don't think coherent ever used it. The random polarized one is rated >2mW. The linear polarized one is rated for >1mW. The coherent ones are actually made by Melles griot, just rebadged...That's why they look the same. :)

Do let me know, I have a Showa GLG-3075 thats just being an expensive paperweight at this point, wondering if I could rewire it to work with the GLS-3080.
