Monochromatic aberrations can limit the quality of microscope images.
Correcting for these aberrations is what drives up the cost of inspection systems. The wavelength of light affects microscope optical-system performance. The source of light you use with a microscope makes the difference between good and poor images. Understanding the science behind optical systems makes it easier to know what specs to ask about when buying a microscope. The real test of a microscope's quality is how it operates for you.
