Focal Plane Arrays

We manufacture and sell three standard QWIP focal plane arrays. All FPAs are spec-compliant, and delivered either in an LCC or on a customer-supplied substrate. A rigorous test report and the QmagiQ Guarantee accompanies each FPA.

  • Falcon 256:
    320x256 FPA, mid-format 1-Color LWIR, on ISC9705 ROIC
  • Hawk 512:
    640x512 FPA, large-format 1-Color LWIR, on ISC9803 ROIC
  • Eagle 256:
    320x256 FPA, mid-format 2-Color MWIR/LWIR, on ISC0006 ROIC

Custom detector design is available to tailor the response of our QWIP arrays to the unique spectral requirements of your application. The available wavelength range is 4-12µm.

We also offer custom QWIP FPAs built on the ROIC of your choice. If you are already using this ROIC, you can expand your product line into the LWIR imaging/thermography space by having QmagiQ build a QWIP FPA on it. Your existing system stays the same, all you may need to do is switch to a lens with a LWIR passband.

Contact us to find out how you can get a QWIP FPA on your ROIC.
