The ultra-sensitive SOM optical microphone captures a range of sound from normal
conversation to soft whispering or the shuffling of papers with excellent sound accuracy.
The SOM is based on our unique optical sensor technology. A beam of light is sent
through an optical fiber to a sound sensitive membrane. Sound signals causes the
membrane to vibrate and modulate the intensity of the light reflected off the membrane,
which is then translated into an electrical signal.
The SOM delivers a high signal to noise (S/N) ratio, so even very low-level sound inputs
can be heard clearly and accurately from many meters away. With an omni-directional polar
pattern, the SOM can capture sound from all directions, thereby maximizing voice
representation. The SOM.s excellent frequency response provides true-to-source sound
reproduction.
The SOM cannot be detected by electromagnetic means, since the microphone head
neither contains metal parts nor generates electromagnetic fields and is separated from its
electronic components by many meters of optical fiber. With its miniature dimensions and
versatile configurations, the SOM can be installed in a variety of ways to elude discovery
both by the naked eye and sophisticated detection equipment such as non-linear junction
detectors. Because of its RFI and EMI immunity, the SOM can continue to operate even in
the harshest of environments, without any effect on its performance. These capabilities
and characteristics have made the SOM the microphone of choice among law
enforcement agencies.

The SOM can be customized for your needs, with the following variables: fiber length, fiber
type, fiber color, and the head type. SOM Options include: Noise reduction software,
extension cable, SOM Extra with built in battery and volume control and recording device.
The SOM can be used for a variety of other applications, including RFI testing laboratories,
medical systems and monitoring sound in harsh environments.
