Yes I'm not a physicist by any means, but from what I gather, for the Bayer sensor each photon passes thru one filter [but,] for Foveon, in order for the photon to reach the lowest layer it must travel thru 2 filters, each with some light loss plus the light loss for the silicon sensors themselves.

A popular view - but some red photons pass through silicon almost unimpeded - as in with virtually no loss.

And silicon is transparent to IR, no matter how many "layers" it passes through ...

If that's the case, then why do sensors need IR-cut filters Ted?

If you really don't know, Scott, pop the filter out of your Merrill and go take a daylight shot outside ...

... the OOC JPEG will answer your question, I reckon.

Well, I guess the silicon just isn't so transparent to IR light after-all then, huh?

Very clever, and let's keep it as vague as possible, huh?

That way, nobody will know what band of IR we're taking about and I will be made to look like a fool.

Good for you, well done ....
