World’s first membrane-free microphone

XARION Laser Acoustics is a provider of unique, laser-based acoustic sensors. The membrane-free optical microphone uses an IP-protected principle of operation: it detects sound based on its ability to change the speed of light. Since no mechanically movable or deformable parts are involved in this approach, the sensor comes with a linear frequency response free from mechanical resonances. The microphone shows an unprecedented frequency bandwidth exceeding state of the art solutions by a factor of ten.


No moving parts, unprecedented frequency range, true impulse response. Explore the unique capabilities of a membrane-free optical microphone.
