Small optical disc for project.

[madgadget]

Wondering if anyone here can help. And I cant think of a better place to ask this.

I'm making a little device that will shine light through a liquid and measure how much of this light is lost, so essentially how clear or not it is, I already have it working as prototype, but need to make something more "solid" I need to find somewhere that I can get small glass discs I can use as an optical window to keep the sensor away from the liquid. I'm guessing i need something thats about 8-10mm dia and 2-3mm thick.

Any suggestions!?

Cheers!

AR coated disks suitable for prototyping come from SurplusShed.com

after that, you need a production supplier, some one will suggest Edmund optics but their prices can be beat elsewhere.

Thanks Steve,

I knew this would be the place to ask, I'll see what they have.

Cheers,

Melles Griot also makes these things, they call them Windows.
