1.3.1. Optical Measuring Head

The optical measuring head (hereafter, measuring head) consists of the following parts:
−
Optical detection system;
−
Universal objective;
−
Universal objective holder;
−
Probe holder.
The optical cantilever deflection detection system 1 is mounted on the objective holder 2
(Fig. 1-4). The objective is suspended in an arrangement of elastically deformed arms.
This arrangement provides high accuracy of focusing and mechanical stability of the
device. The head mount 3 is equipped with microscrews for positioning the probe.
