Abstract

A device for analyzing a material using illumination and optical sensing, has a probe (120) arranged to provide the illumination and for receiving light for the optical sensing, and having an optical grating (100) at a contact region of the probe for use in detecting contact pressure of the contact region on the material. A sensor senses light affected by the grating, and a controller (85) controls a contact pressure of the probe on the material, according to the determined contact pressure. By using a grating, there is little or no additional complexity in the construction of the probe, and little or no addition in the contact area of the probe. By determining contact pressure and adapting the probe position, interference effects in the analysis of the material caused by or made worse by contact pressure being too high or too low or fluctuating too much, can be reduced or avoided.
