If an optically active sample is brought between these filters, light will pass again. By turning one of the filters to relocate the dark position, the amount of rotation introduced by the sample can be measured. Quartz wedge polarimeters use a quartz wedge instead of the rotating analyzer. The wedge is moved across the beam until the rotation ...

Halogen lamps consist of a tungsten filament inside a quartz envelope that is filled with halogen gas. In halogen lamps, the quartz envelope is closer to the filament than the glass used in conventional light bulbs. Heating the filament to a high temperature causes the tungsten atoms to evaporate and combine with the halogen gas.
