[QUOTE="Optimet, post: 114242, member: 10102"] *** - You are correct in what you say but if you move from white to blue you have one wavelength of light to look at and to eliminate interference from other wavelengths (like in a white light scanner) you use a narrow band pass filter oin the input of the camera this way the ambient noise does not play into the measurement. For white light scanners you can not do this so inherently you get more environmental noise. The blue system should have a better signal to noise ratio. [/QUOTE]
