The IR go reflected?
(sorry if is old question and DUM).

That depends entirely on the dichros.
The pass green/refelect blu and the pass green/reflect red may reflect IR too.
... or they may not, it just depends on their make.
Just like your galvo mirrors, if coated for visible they might stop IR too.
Dichros behave oddly outside their intended range.

Nothings stops IR better than a dedicated IR band-stop filter, like fitted on all professional lasers.
