The human eye perceives wavelengths between 0.400 μm (blue) and 0.700 μm (red) as white light. Standard lenses are optimized for white light, but issues can arise with non-white light sources in digital camera-based vision systems. Defining lighting requirements early is crucial. A case example using a 75 mm f/3.0 lens is discussed, focusing on selecting wavelengths and achieving desired modulation transfer function (MTF) values.
