The Eta100 Ultra thin-film optical microphone is capable of listening to the entire bandwidth of sound frequencies that physically travel through the air. Using a single sensing head, this patented sensor technology covers a frequency bandwidth from 10 Hz to 1 million Hz and is designed for very high sound pressure levels (up to 180 dB).
