Small sapphire map and ratio with SPTS map
I aligned again the HeNe probe and made the calibration on the surface sample and on the bulk sample. Incident power= 35mW
I repeated the measurement on the small sapphire sample: a scan on the center, and a map at half thickness (according to the scan). Incident power 10W.
Then I made the ratio between my map and the one measured at SPTS as I did in entry 985. The ratio is now 1.17+/-0.2.
