3. Lithium tantalate;
4. Polyvinylidene fluoride and variants; or
5. Strontium barium niobate and variants.
c. "Focal plane arrays" specially designed or modified to achieve 'charge multiplication' and limited by design to have a maximum "radiant sensitivity" of 10 mA/W or less for wavelengths exceeding 760 nm, having all of the following:
1. Incorporating a response limiting mechanism designed not to be removed or modified; and
2. Any of the following:
a. The response limiting mechanism is integral to or combined with the detector element; or
b. The "focal plane array" is only operable with the response limiting mechanism in place.
