Setting of the Incidence Angle
You can only perform analysis in reflection mode. Angle of incidence has to be set to the appropriate
value.
The incidence angle indicator consists of two rings. One ring is fixed while the second one is free.
This allows the sample holder to rotate in order to change the incidence angle. This second ring can
be tightened to avoid changes of the incidence angle. The way of reading the incidence angle indica-
tor is described in the picture below. The longest line represents the incidence angle equal to 0° (2).
Each short line represents 2° of incidence angle (4). The medium long lines represent 10° of inci-
dence angle (3). Then, the indicator (1) serves to read the total incidence angle.
The sample holder is equipped with a positioning pin to avoid any position mistake and an incidence
angle indicator to read the incidence angle.

2- Incidence angle equal to 0°
3- Medium line 10° of incidence angle
4- Short line 2° of incidence angle
