The three primary colors, red, green and blue, combine to form white light. The tint of white depends on the color temperature of the light. When color temperature is high, more blue light exists. When color temperature is low, there’s more red light. Light Balancing Filters correct artificial lighting, so colors appear more natural. For example, by blocking most of the blue portion of the spectrum transmitted by cool white LED lamps, the object being inspected has a more natural look to the human eye. Light Balancing Filters are a better option for correcting color than computer software, which can degrade resolution. When possible, it’s always better to balance light with optics than software.
