DLP4500: Could i use DLP4500 with IR LED of 940nm or 850nm?

Hello,

I was trying to use IR LED of 940 or 850nm with DLP4500. (it is not DLP 4500 NIR.) 

But, 940 and 850nm light wasn't measured by spectrometer when i used the light source.

Does DMD window have an ir filtering function?



Thanks a lot.

Kim
