QUARTZ OSCILLATOR QO 40A1
 |
|
|
This instrument provides
a useful, progressive indication of coating thickness during the coating process,
making reproducible coatings possible. The thickness of both evaporated or sputter
coated films can be monitored by this instrument. Its function is based on quartz
crystals which oscillate at varying rates depending on the thickness of a coating
and some constant factors,
such a size of the crystal and the electric current applied.
The sensor head is a water cooled non-magnetic housing which is permanently
positioned in the vacuum system.
Crystal face is parallel to the water tubes. The QO 40A1 is mounted on the DN
40CF flange with two 3
tubes and Microdot S-50 coaxial connector.
