EXTINCTION RATIO

Hinds Instruments Extinction Ratio (ER) measurement instrument is combined with the Polarization Extinction Ratio (PER) instrument to provide a tool for measuring polarization properties of optical components.  A block diagram of the instrument configured for ER measurement is depicted here.



ER is calculated as a ratio of the power transmitted when the sample polarizing element is aligned with the instruments polarizer divided by the transmission when the two elements are crossed.
