MODULATORS :: PRODUCTS:: PEM-100 Controller
The PEM-100 Controller performs many functions in the photoelastic modulator system. Its primary function is to control the peak retardation of the photoelastic modulator optical head.
It does this by providing a DC voltage signal to the electronic head which determines the transducer vibration amplitude and thus the strain amplitude in the optical element. A current feedback loop from the electronic head enables the controller to maintain stable peak retardation levels.
The PEM-100 Controller has many distinct advantages over the PEM-90 systems. The PEM-100 has an updated user interfaces that allows for easier entry of retardation and wavelength values. The PEM-100 allows users to store frequently used settings for later use. Also, the PEM-100 comes with PEM-100 software allowing for photoelastic modulator systems to be controlled with a computer.
