Measures transmission signal directly through the panel. Measures both material band edge (if present) and Integrated Band Absorption (IBA) values simultaneously.
Description
The Transmission metrology tool measures transmission signal directly through the panel. It measures both material band edge (if present) and Integrated Band Absorption (IBA) values simultaneously.
Details
- The tool continually recalibrates between every panel by making a full transmission measurement between panels.
- An integrating sphere on the underside (transmission) collects all signal for proper, absolute transmission and IBA measurement.
- The tool detects panels through a threshold signal level (peak intensity of raw spectrometer signal below between-panel transmission signal).
- Standard systems include 2 probes per tool.
