Used mainly on digital and video cameras with CCD sensors without an integrated IR protection filter, because the IR sensitivity of the CCD sensor would otherwise cause color changes and unsharpness.
That unsharpness results from the chromatic aberration of the lenses that are only corrected for visible light.
In the visible range, the transmission curve is very high and straight.
