Surface morphology and roughness analysis using MicroGlider

Sample surface morphology and topography can be examined using a new imaging measuring instrument for the optical analysis of roughness (MicroGlider, Fries Research & Technology GmbH (FRT), Germany). The latter device makes use of the chromatic aberration of optical lenses. This measuring method can be described as follows: The sample is illuminated by focused white light from a halogen lamp. An optical lens with large chromatic aberration fans out the white light in different coloured focal points. By meeting the surface, the focused light will be optimally reflected to a spectrometer via the same lens. The wavelength of the reflected light along with a calibration table reveals the distance from sensor to sample. This method can be generally used as a complementary method to the AFM technique because of its large scale vertical resolution from 10 nm to 300 µm as well as of the possibility to investigate samples with the maximal size area of 100 x 100 mm2. The lateral resolution is, however, determined by the size of the reflected light on the sample: 1-2 µm.
