So here in the chicago area we have a store that sells all kinds of wacky science surplus parts/toys/gadgets/and just plain weird things (for example: brake pads from an f-15 fighter jet)
I took a friend of mine there for his first time yesterday and happened to notice a big pile of HeNe heads on a shelf behind a counter. I asked one of the guys working there if there was any way to test one before I bought it and he had no idea. He said I was the first person to ever ask about them. He brought the whole pile down for me and they were all assorted lengths and sizes 3-5mw The heads were $35 each and the power supplies were $20
They were mostly made in the 80's and one had a xerox label on it.
I really know nothing about these and im wondering if i should go back and get one for the price?
There were no wavelength stamped on them only output power and serial numbers and dates.
Is there any way to guess the wavelengths of these if i was to go buy one?
