Luxo - LED vs. Fiber Optic Illumination

Our thanks to Luxo for allowing us to reprint the following.


Today's microscopes offer an extensive selection of light sources to suit individual preferences, technical requirements and workplace conditions and applications. While users appreciate the various options available to them, selecting a light source to meet their specific needs can be overwhelming. What follows below is a comparison between the two most common microscope light sources: LED and Fiber Optic.

As with many light sources, the balance between energy consumption, light output, color temperature and lumen maintenance 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 the detailed inspection of circuit boards, welds, solder joints, flux residues and hairline stress cracks.


Energy Consumption


An ideal light source will produce the greatest amount of light while using the least amount of energy. Numerous LED and Fiber Optic light sources available today provide dimming options which help to lessen energy consumption and increase lumen maintenance. today's technicians are always searching for the most energyefficient alternative to meet their inspection and assembly needs...
