[rescue] OT - Optics / Laser rescue bits?

[Christopher Purdy]

I currently just have a 3mw HeNe Melles Griot head and supply to
tinker with... but have wanted to try another wavelength for some
time...  I grew up looking at the old Edmund Scientific Catalogs and
drooling at the equipment in there...

It is amazing how much diode technology has improved - nearly 1W from
a diode in a penlight??? crazy is right - I imagine lots for
uneducated folks are cooking their retinas...

I still lean more to the classical tube setup - seems more "correct"
to my mind from what I always lusted after in the industrial catalogs
growing up...

Regarding the Spectra - Ian you have an email waiting for you.. :)
