I'm planning to make a fun project with my wicked extreme40-50mW.
i'm going to purchase a midrange-longrange sniper scope (the ones with
a crosshair), and carefully attach my laser pointer to it so they line
up. . . what i expect to happen is i can use the scope and "aim" at

I will prove that the wave-particle duality theory of light is invalid

I hope to find some super continuum product which can be instantly used
or can be used with minor configuration. Is this commercially available
now?
Thank you!

This one has been nagging at me for a while.  Where does all of the power
required to put on a light show come from.  I know that it ultimately comes
from a dam somewhere, but really...  If you have a laserscope and a medium
power argon laser that would be around 20kw right?  A ...

I have seen quite a few spectra physics 16x series tubes on e-bay
recently, where the cathode bell is made of metal, and was wondering
whether or not it would be feasable to run one of these, pulsed or
quasi CW. I figure that by using the metal cathode bell as the cathode

I have placed 74 laser and optics books from my collection on E-bay
for anyone interested. Check it out.

I just bought a digital microscope and it only came with a 30x lens.
I'm thinking about getting another one, either 100x or 200x but I don't
have any experience using these so I'm asking for advice on which to
choose.  I'm planning to use it for recreational purposes only, just to

Just found this one on the web:
On a microscope:
 Objects are smaller and less alarming than they appear.
This is almost as good as using a microscope as a nutcracker ;-)

My son is receiving my father's old (early 1970's) Nikon Ske phase
contrast microscope. I remember my father showing me slides he had
prepared using darkfield illumination, but how he did it I don't
remember. My son is currently 11 but is very advanced. His reading

I need to improve the images obtained from the confocal microscope for
contrast, reduce noise and reduce the out of focus information in the
image.  I tried deconvolution; but I'm not yet satisfied with the
results.  I would like to have pitch black background with only the

Anyone know where I can find some tubing like the stuff in this picture (for
enclosing the beam path)?  I have the same YAG laser but these tubes are
missing.  What is this tubing called?
