(no longer available)

Radiometric Thermal Imaging Camera

Fast, Rugged, Simple:

The 221 is a calibrated, radiometric, real-time thermal imaging camera.  It requires little power and needs no cryogenic cooling. The 221 uses an amorphous silicon micro-bolometer detector and produces 160x120 pixel images. Combined with a personal computer (not included) and WinTES2 camera control software (included), the 221 provides fast, easy image capture, analysis, and image storage.
