Lab arm?

Hey guys,

What's that little lab arm/hand used to hold lenses and or lasers into a fixed but movable position? I'm trying to find one but I don't even know what it's called.... :

Thanks!

I think you mean a helping hand: http://www.amazon.com/s/ref=nb_ss_?url=search-alias=aps&field-keywords=helping+hand&x=0&y=0

Exactly that! Thanks!

I thought you meant like an adjustable optics mount...

Something like this: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=220307227567

Those helping hands are great for holding things while you solder, but as for aligning optics, they have a bit of "play" or "give", and aren't very good for holding anything with any kind of precision or for any real length of time.
