2 Requirements Review SectionRequirementAcceptance Criteria APackage Dimensions and performance Mechanical drawing DELIVERABLE documenting that Vacuum package measures less than given dimensions in section A and support electronics measure less than 5.5”x7”x7” or can be placed more than 36” away Mechanical measurement DELIVERABLE documenting demonstrated leak rate consistent with 30 mTorr 3 months after pump down BWeight Mechanical measurement DELIVERABLE documenting weight less than 25 pounds fully integrated and flight ready with support electronics and other structures required operationally CVibration Mechanical drawing DELIVERABLE documenting construction includes vibration mitigating thermal links DShock, Altitude and Flight Worthiness The COB must demonstrate the ability to operate and maintain optical alignment after undergoing a shake test at the frequencies and amplitudes given in section D. The COB must demonstrate the ability to operate and maintain optical alignment after/while undergoing a temperature and pressure chamber test consistent with 65000ft mission. AMES has facilities and proceedures to run vibration and altitude/temperature testing. The proposal may include use of these facilities for performance validation of the requirement 2D. The vibration, altitude and temperature testing is not to cause any change in alignment, signal or noise Temperature stability.

3 Requirements Review Section RequirementAcceptance Criteria ETemperature Requirements Mechanical measurement DELIVERABLE documenting: The COB instrument must demonstrate 77K FPA temperatures and 160K shroud/optics temperature at steady state for 8 hours. The COB instrument must reach a steady state operating temperature (77K FPA, 160K shroud/optics) within 45 minutes before the 8 hour test without use of cryogens to boost cold soak The instrument must demonstrate a +/-10mK pk-pk stability over the 8 hour temperature test cooled TIA amplifier stage reaches +/-10 mK pk-pk stability within 45 min. FFPA Design Optical design DELIVERABLE documenting system etendue defined by the entrance pupil and field stop are maintained in the COB. Optical Measurement DELIVERABLE documenting COB entrance pupil and FOV are consistent with the system etendue. GElectronicsMechanical drawing DELIVERABLE documenting that: TIAs delivered are within 3” of the detectors TIAs are on a stable cold stage inside the vacuum envelope Detectors, TIAs and signal lines to the vacuum bulkhead are encased in an easily grounded shielding

4 Requirements Review SectionRequirementAcceptance Criteria HOptical Optical design DELIVERABLE documenting COB entrance pupil clear aperture matches that of the exit pupil of the telescopic fore-optic Vendor supplied dichroic transmission measurement DELIVERABLE demonstrating Transmittance greater than 95% for the bands listed in the table in section J above and reflectance greater than 95% over µm. Optical design DELIVERABLE documenting that the COB FOV is 15 mRad. Optical design DELIVERABLE documenting the absence of vignetting Optical design DELIVERABLE modeling expected polarization sensitivity Optical Measurement DELIVERABLE detailing results of measurements estimating the COB’s actual entrance pupil, FOV, vignetting. Optical Measurement DELIVERABLE detailing spectral response function for each band IStray Light and Order Sorting Optical Measurement DELIVERABLE detailing that out of band stray light in each spectral band is less than that of a source in all of the other bands. This measurement uses the FTIR technique of LaPorte et al. If the vendor does not have access to an FTIR or lock-in amplifier capable of performing the measurement, resources at the ASF Calibration Lab or NIST may be used. ASF Calibration Lab has such a spectral response measurement capability and NIST is developing it for VIIRS sensors. JSpectral Cross-talk Optical design DELIVERABLE documenting the expected crosstalk from a raytrace model (e.g., Zemax “footprint” analysis) Optical Measurement DELIVERABLE detailing an FTIR measurement following the method of LaPorte et al
