<<Hi Subers;

I'm looking for an US supplier of small (3" to 8" dia.) hemispheric
plastic (acrylic) or glass optical domes to be used with a UW  video
system. 
I have searched thru WWW but without results.
Could anyone point the right source ?  

Thanks for any help.

The most immediate outlet for optically useful domes are the Ritchie Compass 
people.  Check with your local marine supply store for the 800 number and 
call the factory for supplies.  The acrylic domes they use are machined from 
solid blocks and are optically perfect (more or less).  Here's a Trivial 
Pursuit question for you.  Why do you think the original MiniRover from 
Benthos was 10" in diameter.  Answer:  Because that was the largest compass 
housing dome available!!!!!
