Ultrasound Field Characterization
The small size and the linear frequency response make the Optical Microphone the perfect tool for precise measurements of time signals, frequency distributions and acoustic field maps of ultrasound emitters such as air-coupled ultrasonic piezos.

Measurements in High Electromagnetic Fields
Thus, sound can be recorded in applications that are out of reach for classical microphones due to strong EMI or radioactive fields.

Ultra-high Sound Pressure Levels
The Eta100 Ultra was designed to measure extremely high sound pressure levels (up to 180dB SPL). All our microphones are immune to damage by excessive acoustic pressure levels.
