Laser Scanning Confocal Microscopes
Laser Scanning Microscopes
Laser scanning microscopes incorporate two light sources: a white light for gathering colour information, and a laser source for gathering height information. To capture height data, the laser is scanned in the XYZ directions across the surface of the sample, and the reflected light intensity is measured. The result is a high-resolution, large depth-of-field, colour image with nanometre-level height resolution for accurate profile and roughness measurements.
