What Happens to the Near Infared Entering the Camera?

Near infrared doesn't make it to the camera sensor because it is blocked by the infrared-blocking filter,
which lets the visible light through.

What Happens to the Visible Light Entering the Camera?

The visible light reaching the sensor is controlled by small color filters.The red filter lets red light
through, so only this light is hitting the small sensor underneath it. Similarly, the
green and blue filters control the wavelengths of light reaching the sensors beneath them.

So what happens when the infrared-blocking filter is removed?
