Low cost
 Product Description

This plastic scintillator combines the two important properties of long attenuation length And fast timing and is therefore particularly useful for time-of-flight systems Using scintillators greater than one meter long. Typical measurements of 4 meter Optical attenuation length are achieved in strips of cast sheet in which a 
Representative size is 2cm x 20cm x 300cm. 

The combination of long attenuation length, high light output, and emission spectrum well matched to the common photomultipliers recommends it as the detector of choice for many industrial applications such as gauging and environmental protection where high sensitivity of signal uniformity are critical operating requirements.
