Optical microscopes are used to analyse the sample during the preparation process. Nowadays, digital microscopes are widely used. CCD cameras create a digital image. The image is directly shown without using eyepieces. As an advantage these systems offer very high magnification by very low costs.
For analysing the surface of the substrate reflected light microscopes are used. These microscopes employ reflected light to create an image. This allows to analyse even thick samples.
