1 optical path system
 
1) The infrared light source illumination scheme adopts the upper side illumination, and the illumination position of the light source on the sample is consistent with the position of the AFM needle tip. The automatic motor control is realized by adjusting the light path through software
 
2) The software can display the laser hot spot in two-dimensional image, and the software automatically controls the motor to optimize the spot position to achieve a high signal-to-noise ratio
 
3) Modular design, the post-correction of the optical path does not need manual adjustment, optimization of laser spot focus and position can be controlled by software without mutual interference. In order to achieve good results of optical path optimization, the software motor controls the optical path collimator.
