IR Filter These infrared bandpass filter operate from 850nm -
1500nm and can be used to filter out visible light in front of light bulbs
or CCD cameras. Because they allow only the IR spectrum to pass they can be
used to isolate certain types of foliage, heat sources and also can be used
to make IR sensitive CCD cameras invisable to human sight.
