Both sides of each window are then simultaneously ground and polished ( ). Exposed surfaces of the metal plate are electroplated with nickel and gold ( ). One or more coatings ( ) are applied to one or both sides of each window. Several sections are then cut from the assembly, each of which can serve as a lid ( ) for an optical apparatus ( ).
