I am liquidating my laser and optics inventory. I will honour
all offers. Do not be intimidated by the list prices I quote, those
are only for reference. For instance, I'd seriously consider $20 to $50 for
the polarizer that lists for $445 US. If you are interested in all the stuff
then a better deal can be had. For example, an offer of $1300 or so Canadian
dollars for the complete set-up might be interesting. Anything.... make an
offer!
Surplus Mells Griot 5mW laser. Bare 'bottle' in a non-UL approved
housing built by the University of Waterloo Chemical Engineering Machine Shop to
my design. All aluminum, with cooling fan and vent holes (optional to run the
fan, for those vibration critical applictions). Bare tube costs about
$600 Can and housing about $150 Can., I have a powersuply board that requires
a transformer and the board cost about $40 Can. Based on this make an offer.
Opticon HeNe 15X focusable expander with high quality lenses
optimized for 633 nm. Two lens Keplerian design reduces beam to approximately
60cm at 1km. Opticon sells these for about $1200. Make an offer.
