Heating filament
WebTungsten heater filaments are used in high vacuum thin film deposition systems to either heat a small crucible of the heat a substrate discs. The substrate needs to be positioned on the filament coil; for substrate heating temperatures chosen tend to be up to several 100 ° and can be used to influence the properties of the deposited film.
