Focal Plane Arrays
QmagiQ manufactures and sells a variety of standard and custom SLS and 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.
Below is a short list of some of the standard focal planes QmagiQ offers:
- Falcon 256:
320x256 FPA, mid-format 1-Color LWIR QWIP, on ISC9705 ROIC - Hawk 512:
640x512 FPA, large-format 1-Color LWIR QWIP, on ISC9803 ROIC - Eagle 256:
320x256 FPA, mid-format 2-Color MWIR/LWIR QWIP, on ISC0006 ROIC
Custom detector design is available to tailor the response of our focal plane arrays to the unique spectral requirements of your application with wavelength ranges extending out beyond 12µm.
We also offer custom 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 an SLS or 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.
