Flick (physics)

In optical engineering and telecommunications engineering, the flick is a unit of spectral radiance. One flick corresponds to a spectral radiance of 1 watt per steradian per square centimeter of surface per micrometer of span in wavelength (W·sr−1·cm−2·μm−1). This is equivalent to 1010 watts per steradian per cubic meter (W·sr−1·m−3). In practice, spectral radiance is typically measured in microflicks (10-6 flicks).[1] One microflick is equivalent to 10 kilowatts per steradian per cubic meter (kW·sr−1·m−3).[2]
