I thought "hot mirrors" are used to pass visible light and reflect
the infrared back to the source. Or are you implying a different
kind or using it in a different way, say at 45 degrees to the lens?

Roger,
I assume that this won't work with DSLRs that have an IR filter
over the sensor. Is that correct?
I tried it with my Canon Rebel and the combination worked quite well.
Pretty much the same as on the Fuji except for the fact that the Fuji
exposure time for an interior scene was something like 1/30 second
while
the Canon needed something in the order of 30 seconds!! (this is an
estimate
--- I don' recall the exact figures but the Fuji was significantly
faster
due to it not having an IR blocking filter built in. But you can put a
"hot mirror" in front and them it behaves much like any other ccd
camera
with built-in ir blocking filter.
I'll do some more testing ...
