    The Travelling Microscope. The sliding carriage of the traveling microscope rides on carefully machined ways, pushed by a nut under the carriage which rides on the micrometer screw. The nut must not fit tightly on the screw or it will bind; hence there is always some slack built into the mechanism. When the nut is being pulled to the right ...

    The behaviour in Fig-ure 1 is observed if do > f, giving di > 0. Conversely, if do < f, then di < 0, giving the virtual image illustrated in Figure 2. Finally, if do = f, then di → ∞ to give 1/di = 0. Next, two types of magnification may be defined: the linear (or lateral) magnification, and the an-gular magnification.

    The travelling microscope consists of an ordinary compound microscope that can slide along a graduated vertical pillar attached to a horizontal base. It allows microscopic movement in both vertical and horizontal directions using fine adjustment screws. The main scale is divided into 0.5 mm divisions, while the vernier scale has 50 divisions equal to 49 main scale divisions. This gives the ...
