Yes. UV may not be the only problem. Put a big window on a box, let
sunlight in, and IR will make the insides of the box *very* hot. What
is the application? Might want a filter anyway if, say, you want to
be sensitive to direct sun but not to blue sky. A green filter from a
camera shop might be what you want here: let in medium wavelengths
(where your diodes will have their best quantum efficiency anyway),
reject the extremes.
