Processing chamber condition and process state monitoring using optical reflector attached to processing chamber liner

A system includes a reflector attached to a liner of a processing chamber. A light coupling device is to transmit light, from a light source, through a window of the processing chamber directed at the reflector. The light coupling device focuses, into a spectrometer, light received reflected back fr...
