[Laser] Great deal on narrow band interference filters On Ebay

[Kerry Banke]

You guys are going to think I have a vested interest in Ebay but I don't 
:)   I just received email from buyrightauctions indication they have a 
large number of optical interference filters on auction. I bought a few of 
the 650 nm 10nm narrow band  filters and they are great for use with 650 nm 
laser pointers and go for about $2.50 each plus shipping. These are 
cosmetic rejects but great for experimenting. Look under optical 
interference filter or buyrightauctions.
