Hardness testing technologies
Back to overviewThe autofocus system works in two different ways:
With the direct force measurement principle, an integrated load cell registers precisely when the indenter comes into contact with the surface. The optimum focal plane is then already identified during the test cycle based on this force measurement.
Moreover, in the case of lenses with very high magnification levels, the digital camera performs additional automatic focussing.
