Hi Eric and Craig,

I think that seems reasonable.  Eric could you order two?

Best,

Anne

Hi Eric,
   From what I can see, this diffuser looks fine, but it's hard to say a priori how uniform the light output would be given the LED light source you would be using. Since they're not expensive, you might want to order several with different grit polishes and see how they look. They do seem to give reasonable overall transmission (~ 80%), so you could even try using two of them in tandem if necessary. The main thing will be to see how uniform the light distribution from the diffuser looks with the camera.

Cheers,
Craig
