Our Optimic™ fiber optical microphone is ideal for high sound pressure level (SPL) monitoring in MRI and other excessive noise environments. Optoacoustics’ unique MEMS design makes this the only commercial microphone that can be used during an MRI scan inside a patient’s ear defender or anywhere in the scanner room.
We offer two Optimic™ configurations:
 Optimic™ 1150 (55 – 140 dB)
Optimic™ 2150 (55 – 140 dB, ruggedized)
Optimic™ Features
Small, lightweight MEMS design
Linear response of up to 140 dB
Excellent sound accuracy at high SPL
Complete EMI/RFI immunity means no effect on
MR imaging
Electrical insulation at high voltages
Wide frequency range
Enables optical fiber lengths from 20 to 100 meters
without signal loss
