  • What do you do at the Institution that potentially demands high performance, solid state, technical lighting?
  • Operating a Light Microscopy Core is challenging because scientists demand high performance illumination for a variety of fluorescent sample types in which sensitivity and lower detection limits vary significantly. We see samples including cells and tissues that have been labeled with dyes, antibodies and fluorescent proteins. We rely heavily on our LED systems to provide Illumination whenever we need it.
  • What are some of the challenges that need to be overcome to ensure optimal performance for imaging or quantitation?
  • In order to satisfy the demands of hundreds of investigators we must provide illumination that offers sufficient intensity and stability. The Lumencor products have met our standards and the ability to turn them on and off at will has made fluorescence illumination easier.
  • How have Lumencor’s products addressed these challenges?
  • Since we have changed all of our mercury sources over to the Lumencor SOLA light engines there have not been any complaints regarding brightness, stability or ease of use. We expect that the switch to LED sources will decrease our expenses with regard to utilities and hazardous waste removal. The LED sources will also provide a safer workplace by removing the risk of explosion of mercury bulbs and from mercury exposure from broken bulbs. The switch to LED sources will also help us to further our long term goal of reducing greenhouse gases and hazardous waste.
