Optix is a highly robust and sensitive, multi-purpose instrument for gas sensing in any vacuum environment, functioning through a wide range of operating pressures to cater for all industrial vacuum production processes without any requirement for differential pumping.
Optix uses a remote plasma spectroscopy concept which generates a small plasma within the sensor head, and is then analysed by its built-in spectrometer. The light spectrum is automatically interpreted to provide quantitative measurement of the presence and concentration of gas within the vacuum expressed as a partial pressure of the relevant gases. As the plasma light detector is located outside the vacuum, it’s virtually impossible to break the instrument.
Optix generates a plasma and senses gases over a wide pressure range without the need for a differential pumping system. It automatically switches on and off at 0.5 mbar and provides accurate pressure and gas information down to 10-6 mbar.
The Optix spectral information and sophisticated back-end software creates a range of uses for all vacuum users within an easy to use and multi-functional interface: wide range pressure measurement; leak detection; vacuum quality monitoring; process pump-down analysis; gas and molecular analysis; condition monitoring and fault detection; fast process feedback and flow control; end-point detection; gas flow calibration and composition ratios.
Small changes are made to the device in the case of sensing CVD and ALD type processes in order to prevent contamination of the plasma head. Sensing from atmosphere is also possible with a small roughing pump to bring the gases into the sensor.
Optix is very portable and easily switched between different vacuum systems or hand-carried in a small box to customer sites. It also offers an ultra-high sensitivity single gas option for dedicated leak detection.
