[meteorite-list] Polarizers way cheap! Big ones!

[STARSANDSCOPES at aol.com]

Hi list,  All my images involve polarizers  in one way or an other and over 
the last couple years I have had many inquiries  of where to get polarizers 
cheap.   I haven't had a solution other  than scrounge them at yard sales etc.

I just found an eBay seller that  has 82mm PL for $8.50.  This is way cheap 
for these big ones.  I  bought a couple and they are quality made in Japan with 
total extinction.   The eBay # is  170282710765  Normal retail on a polarizer 
this size is  usually several times this price.  They are linier polarizers 
and not  circular polarizers which is perfect for meteorite Xpol  application.

Check out my Micro Vision article in the Jan 2007 Meteorite  Times Cross 
titled Polarized Light Hand Sample Examination.  The link is  
http://www.meteorite.com/meteorite-gallery/Micro_Visions.htm   This  will give you an idea of what 
polarizers can do in meteorite examination and you  don't necessarily need a 
microscope.

With two 82mm filters you could make  a thin section viewing set.  These are 
big enough for a standard microscope  slide to fit inside the filter holder.

I'm not selling any thing, I just  thought some of you might like to know.

Also, while you are at Meteorite  Times, check out this months MV on NWA 3151 
Brachinite.  It has three  killer shots from Bernd Pauli in wide field cross 
polarized light.
