Lock-in thermography

LIT is still the best method for localizing shunts, but also offers other information about recombination, series resistance, etc. The lock-in principle makes the resolution a matter of modulation frequency and time. Shunts in samples without contacts can be measured under illumination with modulated IR-light (ILIT)

The scientific thermal camera is motorized in height and focus and automatically adjusts to the sample size. A zoom mode uses the minimum possible object distance for high resolution close-ups. The images are scaled to mm.
