Mirror
This mirror directs the laser beam to the photodiode after it is reflected by the cantilever.
Mirror angle-adjustment knob
Adjusts the mirror angle so that the laser beam irradiates the detector correctly. Loosen
the mirror fastening screw; then adjust the mirror angle by turning the mirror
angle-adjustment knob. Tighten the screw.
For more information on mirror adjustment, refer to Chapter 8.3.2, "Mirror Angle
Adjustment."
Preamplifier
A preamplifier for the photodiode detector output and a preamplifier for STM tunneling
current are housed in the SPM head unit.
SPM base unit connectors
Connects the SPM head unit to the SPM base unit.
Cantilever holder
The holder on which the cantilever is mounted. The cantilever holder is inserted into the
SPM head unit.
Tip holder
The holder on which the tip for STM observation is mounted. The tip holder is inserted
into the SPM head unit when installing a tip for observation.
