OFC-1 Pulsed Optical Frequency Counter


Introducing the OFC-1 Pulsed Optical Frequency Counter:

A growing number of people are suffering from eye fatigue, headaches and discomfort with computers, TVs, tablets, cellphones, and modern indoor lighting. New lights and display backlights are often pulsed on & off hundreds of times per second for brightness control. They appear to be steady illumination, but are actually flashing very quickly. These extreme pulses of light can be tiring and a source of discomfort for many. The OFC-1 allows you to hear the sound of these light pulses and see their frequency in real time.
  • Displays dominant frequency of light from source.
  • Range selection - Display in Hz or kHz.
  • Adjustable volume.
 Applications:
  • Identify problem light sources.
  • "Hear" what your eyes are seeing.
  • Measure the frequency of pulsed light.
  • TV, Monitor, Laptop display pulse width modulation (PWM) testing.
  • Analog lightwave audio receiver.
