Today's microscopes offer an extensive selection of lightsources to suit individual preferences, technical requirements and workplace conditions and applications. While users appreciate the various options available to them, selecting a lightsource to meet their specific needs can be overwhelming. What follows is a comparison between the two common microscope lightsources: LED and Fiber Optic.
As with many lightsources, the balance between energy consumption, light output, color temperature and lightsource life requires a careful understanding of the tasks which are to be performed. While Fiber Optic lighting is preferred for jobs such as wire bonding or soldering of fine-pitch components, pure white LED light is preferred for detailed inspection of circuit boards, welds, solder joints, flux residues and hairline stress cracks.
