Opacity Many minerals and crystals are even when thin sectioned (30 µm) not transparent. Also sections of metal samples or polished blocks are truly ...
Polishing A polishing disk is covered with polishing cloth impregnated with a polishing medium (diamond particles) and a oily lubricant. Mostly two polishing steps ...
Reflected Darkfield Microscopy Darkfield illumination with reflected light enables visualisation of grain boundaries, surface defects, and other features that are difficult or impossible to detect with ...
Reflectivity Some minerals do not show transparency in thin sections. They are opaque. Opaque minerals can not be observed with a transmission light microscope. In this case a reflected ...
Relief In thin sections grains appear in different textures, with different structural details, or with different “heights”. The physical reason for this appearance of relief is a difference between ...
Time Lapse Imaging (in Material Science) Dynamic processes such as crystal growth, can be monitored routinely nowadays. The duration of such processes may vary from the sub-second range to hours or days.
