Friend or Foe Identification

The markIR Tuned Band Emitters utilize a two-dimensional photonic crystal structure to tune and restrict the IR emission for visibility in only the desired spectral region. These miniature devices provide high energy Infrared signals with minimal power consumption, thus enabling long-range visibility and prolonged battery operation. Each hermetically sealed device contains 2 elements which may be coupled together or independently driven in pulsed or constant modes.
