    Default Loads Of He Ne Lasers

    Some time ago, I received a box of He Ne lasers from George at Chameleon Technology. Also included was an NEC PSU brick. Unfortunately, I have never managed to get this to work on 240V and I dont have access to a 110V supply. Last week, I purchased another power supply, but this one doesnt have enough guts to power the bigger tubes; and the smaller ones arent fitted with alden connectors.

    Therefore instead of powering up each tube and putting them on ebay individually, I am just going to sell the lot in one hit at a discounted price. If you have access to a big He Ne PSU and some alden connectors, then you are laughing.

    Anyway, here is what is on offer. Model numbers in brackets.

    2 x NEC 20mW He Ne tubes (GLG5400) 40, 1 SOLD



    1 x Laser Chorus 1mW Green He Ne tube (LHGR-0035) 60 **SOLD**



    1 x Coherent 5mW He Ne tube (HeNe-SPL) 12.50
    1 x Hughes 10mW He Ne tube (3225H-C) 15



    3 x Unspecified 2mW tubes 15


    2 x Spectra Physics 3-5mW tubes - appear new & unused (SL010) 20 **SOLD**



    1 x Siemens 2mW tube - probably only useful for a desk ornament (LGR7632) 5


    1 x NEC PSU brick (GLS5400A) 40



    1 x Lasr Drive PSU brick - less than 1 week old (111-2400-5) 40



    Now to try and put a value on this lot. Considering how many tubes there are I think 250 is a fair price for everything listed. I am open to offers and trades and making a deal of some kind. I am happy to ship this lot worldwide. I have recently purchased lots of bubble wrap and foam rubber. I have access to some good boxes at work and I guarantee these will be very well packaged.

    As a guide, for postage (including packing materials) 15 Uk, 25 Europe, 45 USA. This is using a courier with a 3-4 day service as opposed to the post office and a 2 week service (which isnt really any cheaper).

    A gratuitous photo of everything. Feed your addiction!!

    I like the typo on the 2nd to last picture.
    apparently it is an over unity device, and creates more power then it consumes!
    (says 5.25A instead or 5.25mA, lol)

    Some pretty tubes!

    Yeah, thats rather good.

    Mind you, 2.5Kv @ 5A wouldnt half give you a belt.

    I have had a few enquiries about splitting these items. I have therefore priced everything individually. The prices quoted include UK postage and paypal fees. I am happy to post anything worldwide at additional cost.

    Genuine offers and trades are invited.

    I have the same siemens tube in the 1mW version and it is really nice for someone to demonstrate plasma lasing

    It is easy to power up with a simple air ioniser transformer, a voltage multiplier to give the starting voltage of approximately 7kV, and a current limiting resistor calculated for approximately 5mA of current

    No beam shots due to lack of PSU, but PM sent.

    I can ship to the USA.

    Shouldnt cost too much either, as they arent very heavy.
