Light Entering a Camera

Jump to [visible light]

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.

Infrared light enters the camera, IR-Blocking filter stops nearly all IR from reaching sensors, Color filters control the color light reaching a sensor. Color blind sensors convert light reaching each sensor into electricity.

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.

Incoming visible light passes through the IR-Blocking Filter. The Color Filters control the color light reaching a sensor, and then Color blind sensors convert light reaching each sensor into electricity.


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