METHOD OF MOUNTING GALVANOMETER MIRROR

摘要

A metal mount of a galvanometer is secured to a plate made of an electrically conductive material via a thin insulating layer in electrically insulated relation to the plate. The thin insulating layer has a thickness within the range of about 10 mu m to about 500 mu m. The metal mount and the thin insulating layer are cylindrical and are secured to a cylindrical through hole formed in the plate. Or, the metal mount has an L-shaped cross-section. One section of the L-shaped metal mount is secured to the plate by use of bolts, and the other section thereof is secured to the galvanometer by use of screws. In this case, an insulation sheet is positioned between the one section of the L-shaped metal mount and the plate.
