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.
                       Technical Note:
                       For the purposes of 6A002.a.3. Note 2.c.2.a., a response limiting mechanism integral to the detector element is designed not to be removed or modified without rendering the detector inoperable.
                       d. Thermopile arrays having less than 5,130 elements;
6. A. 002. a. 3. a. Non‑"space‑qualified" "focal plane arrays" having all of the following:
1. Individual elements with a peak response within the wavelength range exceeding 900 nm but not exceeding 1,050 nm; and
2. Any of the following:
a. A response "time constant" of less than 0.5 ns; or
b. Specially designed or modified to achieve 'charge multiplication' and having a maximum "radiant sensitivity" exceeding 10 mA/W;
6. A. 002. a. 3. b. Non‑"space‑qualified" "focal plane arrays" having all of the following:
1. Individual elements with a peak response in the wavelength range exceeding 1,050 nm but not exceeding 1,200 nm; and
2. Any of the following:
a. A response "time constant" of 95 ns or less; or
b. Specially designed or modified to achieve 'charge multiplication' and having a maximum "radiant sensitivity" exceeding 10 mA/W;
6. A. 002. a. 3. c. Non‑"space‑qualified" non‑linear (2‑dimensional) "focal plane arrays" having individual elements with a peak response in the wavelength range exceeding 1,200 nm but not exceeding 30,000 nm;
N.B.: Silicon and other material based 'microbolometer' non‑"space‑qualified" "focal plane arrays" are only specified by 6A002.a.3.f.
6. A. 002. a. 3. d. Non‑"space‑qualified" linear (1‑dimensional) "focal plane arrays" having all of the following:
1. Individual elements with a peak response in the wavelength range exceeding 1,200 nm but not exceeding 3,000 nm; and
2. Any of the following:
a. A ratio of 'scan direction' dimension of the detector element to the 'cross‑scan direction' dimension of the detector element of less than 3.8; or
b. Signal processing in the detector elements;
Note: 6A002.a.3.d. does not apply to "focal plane arrays" (not to exceed 32 elements) having detector elements limited solely to germanium material.
                  Technical Note:
For the purposes of 6A002.a.3.d., 'cross‑scan direction' is defined as the axis parallel to the linear array of detector elements and the 'scan direction' is defined as the axis perpendicular to the linear array of detector elements.
6. A. 002. a. 3. e. Non‑"space‑qualified" linear (1‑dimensional) "focal plane arrays" having individual elements with a peak response in the wavelength range exceeding 3,000 nm but not exceeding 30,000 nm;
6. A. 002. a. 3. f. Non‑"space‑qualified" non‑linear (2‑dimensional) infrared "focal plane arrays" based on 'microbolometer' material having individual elements with an unfiltered response in the wavelength range
