confocal laser scanning
Aug. 24, 2014
Confocal laser scanning microscopes (CLMs) are renowned for their sectioning capability. This feature is enabled by the use of pinhole, which rejects out-of-focus light. Less appreciated, on the other hand, is the gain in lateral resolution by this type of microscopes for one obvious reason.

Surface metrology is quickly emerging as a critical analytical technique to determine the topology of various materials. It can be used to identify corrosion, surface characterization, or to control the quality of different surfaces. Conventional methods such as profilometry, have involved the use of a stylus being dragged along the sample surface. However, this technique can be problematic; it cannot be used on certain materials, such as adhesives, and the dragging process itself may result in inaccurate data being obtained.

Corrosion is a big problem. From metal and concrete to polymers and electronics, different forms of decay lead to structural and functional failures that can sometimes be of fundamental importance. The Swedish Corrosion and Metals Institute - Swerea KIMAB, is focused on developing and improving solutions for materials research. As such, they are studying corrosion in its many forms as well as the various methods used to prevent it.

LEXT is utilising low wave length optical technology with a 408nm laser in combination with confocal scanning to exceed known resolution limits of optical imaging systems. By developing a special optical system which minimises the aberrations associated with short wavelength and maximises the transmission at 408nm Olympus achieved unequalled image quality and signal response.
