MIL-PRF-49319A(CR)

3.12.6 Damage. Breakage, loosening, shifting, evidence of corrosion or failure of any finish,

hardware, connection or component; and any degradation of Detector-Dewar performance to values

less than specified herein.

3.12.7 Nominal detector element size. Defined as 0.0016 by 0.0024 inch.

3.12.8 Variation of responsitivity with temperature. When coupled to a cryogenic

refrigerator the temperature of the array may reach 55K under these conditions and the responsivity

(paragraph 3.5.7) may decrease to as low as 5.6 x 103 volts/watt.

3.12.9 Microphonic test caution. The microphonic requirements and test specified herein are

designed to be representative of an operational environment and combat scenario for detectors

mounted in a well designed system using current technology. If the system vibrational levels are

increased above those specified, the microphonic noise may increase.

3.12.10 Detector temperature. Detector-Dewar temperature is defined as that indicated by the

temperature sensor diode.

4. VERIFICATION

4.1 Classification of inspections. The inspections shall be classified as follows:

a. First article inspection (4.2).

b. Conformance inspection (4.3).

4.2 First article inspection. When specified in the contract, first article inspection shall be

performed by the contractor on a minimum of 5 preconditioned (see 3.9) sample Detectors-Dewar.

4.2.1 Inspections. All completed assemblies shall be examined for conformance to the

applicable specifications or drawings.
