Application Note: NUC Tower

For Non-Uniformity Correction (NUC) Testing & For High-volume Manufacturing of Infrared Imagers

Main Highlights

• The CI Systems NUC (Non-Uniformity Correction) Tower is ideal for testing multiple cameras or detectors to obtain a high throughput of NUC tables, including ambient temperature reference.
• A tower structure consisting of multiple UUT imagers along the surface of the array of Blackbodies, conducting the test automatically.

• Configuration (*):

1. Fast NUC process at three different temperatures.
2. Ten high-emissivity and uniformity blackbodies.
3. Five high-emissivity and uniformity ambient plates used for radiometric compensation.
   
   Configuration can be changed to meet customer requirements.
   
   

• System can be used inside or outside an environmental chamber.
• The high-accuracy controllers ensure that all surfaces are within an accuracy better than 0.015°C.
• All blackbody controllers are mounted in a standard 19” rack mount and communicate with one central PC.
  
  (*) Other quantities can be configured according to customer requirements

For enhancing throughput for high-volume manufacturing of IR imagers inside or outside an environmental chamber.
