THEIA Continuous Zoom HD Midwave Infrared Imager
| Key Features |
|---|
| • 1280 × 1024 HD focal plane array — 10 µm pixel pitch InSb detector with NEdT <30 mK |
| • Continuous zoom optics — choice of 15–300 mm or 30–600 mm f/4 zoom covering narrow to wide FOV |
| • Open frame OEM configuration — compact, lightweight package optimized for size, weight, and power (SWaP) |
| • Single integrated communications interface — controls both camera and optics via RS-232, RS-422, Camera Link, or Ethernet |
| • Advanced image processing — Gaussian noise reduction, local area processing, AGLC routines, electronic zoom (1×, 2×, 4×), and false color palettes |
| • Motorized continuous zoom & focus — autofocus routines, temperature curve-fit focus, and electronic/mechanical boresighting provisions |
| • Up to 6 on-board non-uniformity correction (NUC) tables — integrated shutter for one-point NUC |
| • Flexible outputs — HD-SDI digital display video; optional Base Camera Link or GigE data streaming; external sync capability |
