XARION's Eta250 Ultra membrane-free optical microphone is able to listen to the entire acoustic frequency bandwidth that can be physically transmitted through air. The patented sensor technology will cover a range from 10 Hz to 1MHz with a single sensor head. It was specially designed for applications with low self-noise requirements.

XARION의 Eta250 Ultra 멤브레인 프리(membrane-free) 광학 마이크로폰은 공기를 통해 물리적으로 전송될 수 있는 전체 음향 주파수 대역을 수음할 수 있습니다. 특허받은 센서 기술을 바탕으로 단 하나의 센서 헤드만으로 10 Hz에서 1 MHz에 이르는 범위를 커버합니다. 낮은 자기소음(self-noise) 요구 조건을 가진 응용 분야를 위해 특별히 설계되었습니다.

Related Applications

Ultrasound Field Characterization

The small size and the linear frequency response of the detection principle make the Optical Microphone the perfect tool for soundfield characterization: Time signals, frequency distributions and ultrasound field maps of several different ultrasound emitters, such as PMUTs, can be characterized using a single sensor.

Measurements in High Electromagnetic Field

All optical components in the sensor head as well as the optical fiber cabling are insensitive to strong electromagnetic fields. Thus, sound field measurements can be conducted in applications that are out of reach for classical microphones due to strong EM 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 from excessive acoustic pressure levels within the ultrasound field.
