INO offers a characterization service for image intensifier tubes and cameras in the 350–1000 nm range. Systems are characterized under normal operating conditions according to various imaging performance standards, including gain, temporal noise, signal-to-noise ratio (SNR), modulation transfer function (MTF), non-uniformities, and spectral response.
We pay special attention to system behavior under saturation conditions (low to high, constant, pulsed or flash, local or global). More generally, all our assemblies feature flexible designs able to reproduce lighting conditions under real-life operation. High-resolution acquisition of temporal responses makes it possible to identify autogating behavior. The system’s operating temperature can be controlled to reproduce actual operating conditions.
INO stands out for its extended illumination range (spanning over 10 orders of magnitude), high-temporal-resolution dynamic analysis, and ability to reproduce specific operating conditions.

To fully assess a system’s suitability for a given application, characterization can be combined with electricity consumption (power consumption/battery life in relation to ambient temperature) and optical parameters (field of view, distortion, and magnification) measurements, as well as shock and vibration tests.
The assembly can also be used for visible camera characterization. For cameras and detectors that operate in the SWIR band, the spectral range of the characterization assembly extends up to 1.8 mm.
