​Infrared and Visible FPAs

Teledyne Imaging Sensors is a world leader in the design and production of large format IR sensors. We produce the largest IR detectors in the world: 2048x2048 format, 18µm pixel pitch arrays based on our proven HAWAII-2RG readout integrated circuit (ROIC). We are supplying NASA’s James Webb Space Telescope (JWST) with 4096x4096 mosaic FPAs. JWST will replace NASA’s Hubble Space Telescope in the year 2011.

Teledyne Imaging Sensors infrared and visible FPA imager products provide “machine vision,” serving the same function as the human retina of the eye – receiving optical images and converting them into electronic signals. Teledyne Imaging Sensors imaging sensor capability far exceeds that of the human eye; imagers are built to see in low light and infrared. Imagers can also be built to detect and determine an objects temperature and chemical composition.

• Standard FPA products
• Semi-custom products - mating standard readout integrated circuit (ROIC) electronics with custom detectors
• Full custom services, optimized to customer requirements
• FPAs for a wide range of requirements: large format, high-speed, very-low noise, high-dynamic range, background subtraction, special windowing, and on-FPA signal processing
• Robust design for harsh environmental conditions including temperature extremes and radiation exposure
• FPA Handling Recommendations:
  • ​ Handling of ESD sensitive FPAs only at certified workstations to +/- 50V or less.
  • Teledyne recommends the rate of temperature change of FPAs be 5°K per minute or less.
  • Storage temperature for FPAs shall be maintained between 17°C (62°F) and 27°C (82°F).
  • Components may be stored under the above conditions for a minimum of 5 years without degrading the part.
    
  • The FPA should not be exposed to temperature higher than 50°C.
  • FPAs should not be exposed to any solvents or liquids. FPAs should remain in a controlled environment with a relative humidity of 30% to 70% non-condensing.
  • Care must be taken to avoid mechanical shock. In addition, extreme care should be taken to avoid contact with wirebonds contained within the FPA assembly.
  • It is not recommended that the Customer attempt to clean the FPA beyond blowing off the FPA with dry nitrogen if it becomes contaminated (25 psi maximum). It is recommended that FPAs ​that become contaminated and require cleaning be shipped back to Teledyne Imaging Sensors.
