Captures wide spectrum (emission) from (plasma) radicals or ions. (200 nm to 950 nm)
Continuously measures up to 15 000 spectra at an interval of 20 msec (50 msec with concurrent running of detection software)
A high resolution spectrometer and a ultra-high sensitive photo detector are firmly locked in position to assure the acquisition of accurate spectrum and precise spectrum responsivity data through sharply focused plasma emission spectrum images.
Detects the UV spectrum region from 200 nm with high sensitivity.
The equipped optical fiber can be easily attached to plasma chambers through a SMA connector widely used.
A single analysis unit can control up to four C10346-01 Multiband plasma-process monitor via a USB 2.0 interface.
The data acquisition software stores the spectrum data into the database during plasma process. This stored data can then be used for spectrum data calculations.
High sensitive endpoint detection and real-time monitoring of process abnormality are achieved by creating ''detection model''.

For modern websites to work according to visitor’s expectations, they need to collect certain basic information about visitors. To do this, a site will create small text files which are placed on visitor’s devices (computer or mobile) - these files are known as cookies when you access a website.
