Abbreviation for working distance, the distance between the observed surface of the sample and the bottom surface of the objective lens This concept is mainly used for scanning electron microscopes where this distance can be changed by raising or lowering the specimen stage Typically this distance can be varied between a few millimetres to 30-40 mm In general the resolution will be better closer to the lens while the depth of focus improves with longer working distance
