High Spectral/Spatial/Temporal Resolution MWIR Hyperspectral Imager

Added 1 new Q&A: Q1 now clarifies that the instrument is intended for ground testing in various facilities (arc, wind tunnel, vacuum chamber, etc.) with no requirement to account for flowfield effects around the instrument.

**Changes to Q&A:** - **New Q1 added:** Clarifies whether imaging should occur through atmospheric shock layer or in space-based optical path (answer not provided) - **Previous Q1-Q8 renumbered to Q2-Q9** (all prior answers remain unchanged)

**Changes Summary:** Added Q1 with explicit answer: Uncooled detectors meeting performance requirements are acceptable. This is the only substantive change; all other Q&As remain identical to the previous version.

Added 1 new Q&A clarifying that uncooled detectors meeting performance requirements are acceptable. All other Q&As renumbered accordingly (Q2-Q7 became Q3-Q8).

Status changed from Pre-Release to Open

**Added Q1 clarifying critical performance requirements:** Full-frame hyperspectral cube data rate threshold of 60 cubes/second (objective 120+); external filter wheels compliant if specs met; 2D snapshots acceptable but 3D preferred. All other Q&As remain unchanged from previous version.

Q1 received a comprehensive answer addressing 7 sub-topics: technical approach flexibility (MEMS acceptable), pixel pitch sufficiency for IFOV, real-time processing not required (post-processing acceptable), HSI cube as desired output, no explicit cost target, one-person liftable preferred (non-threshold), and industrial/desert environment use case with significant component development allowed if development risk addressed.

Added 1 new Q&A (Q1) with 6 sub-questions addressing: MEMS scanner acceptability, minimum IFOV targeting, real-time vs. post-processing requirements, desired data product format (temperature/emissivity vs. HSI cube), target cost/size, environmental considerations, and commercial vs. custom component development allowances.

Q1 received a new answer clarifying field of view flexibility: no specific range required, with optics swappable for different resolutions; instrument usable from 1 meter to 200-250 meters.

Added 1 new Q&A on field of view and sample size requirements. Renumbered existing Q&As (Q2-Q5); all previous answers remain unchanged.

Added 2 new Q&As: Q1 clarifies target temperature range (25°C to 3000°C), and Q2 specifies keystone distortion requirement (≤50% of a pixel, with 10% achievable). Previous Q&As on spectral coverage and pixel pitch units retained without changes.

Added 1 new Q&A clarifying spectral coverage requirements (2-5µm spectrum includes atmospheric absorption regions; all wavelengths required for test facility and static testing applications).

Added answer to Q1 clarifying that detector pixel pitch values are specified in microns (µm), not millimeters (mm).

# Summary This Q&A clarifies detector pixel pitch specifications, asking whether the stated values (30 mm maximum, 15 mm objective) are in millimeters or micrometers—likely seeking confirmation given the significant difference these units would represent.
