Quartz Balance QO 40A1
The Quartz Balance QO 40A1 provides a real-time, progressive indication of coating thickness during deposition, for high accuracy and reproducibility in coatings production.
Manufacturer
Prevac
Prevac are a world leader in the design and production of analytical and deposit scientific and research equipment. Their systems operate in a high and ultra high vacuum environment. They design and construct UHV and HV systems fully adapted to the individual requirements of research projects and industrial applications.
Key Features
- Water-colled sensor head
- Easy exchangeable quartz
Description
The thickness of both evaporated and sputter coated films can be monitored. The sensor head is a water cooled, non-magnetic housing which is permanently positioned in the vacuum system. The crystal face is parallel to the water cooling feedthrough pipes. The Quartz Balance QO 40A1 is mounted on a DN 40CF flange with two Ø6 pipes and Microdot S-50 coaxial connector. Customized insertion length 130 – 500 mm (other on request).
