Figure 3
(a) Image of a 5 µm pinhole at the sample position collected on the Andor iStar camera with the spectrometer in the imaging mode, which is used to co-align the spectrometer and microscope cameras. The red and yellow boxes indicate the vertical pixel range that should be used for the ROI for temperature measurements. (b)–(d) Examples of pyrometry data collected from a 2 µm Pt foil in a DAC which is heated in cw mode on-axis. The software used in this example is T-Rax (Prescher & Prakapenka, 2015). |
