The silicon microbolometer: the basic building block
Amorphous silicon forms the basic building block of ULIS thermal imaging sensors. First developed over thirty years ago, the silicon microbolometer—an infrared imaging sensor that converts infrared radiation into visible images—has reached maturity.
The technology is today used in a broad range of commercial and military applications like thermography (temperature measurement), night vision, surveillance, firefighting, search and rescue, and home energy audits.
ULIS, a leading provider of infrared imaging sensors, uses amorphous silicon microbolometer technology (aSi). Amorphous silicon offers three major advantages:
Sharp images of moving objects
Amorphous silicon reduces the time needed to obtain an image once the camera has been turned on. Because the sensor does not need to be heated or cooled to reach operating temperature, it works virtually instantaneously. In military applications, this shorter time-to-image can save lives.
Low power consumption
Solar immunity design
Competitive pricing and lower total cost of ownership
