Using Different Illumination Sources? Get ready to Change Your Lens Focus
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.
