What are the advantages of a cold light source?
The ambition of any scientific examination is to discover some truth about the sample being investigated, but too often the simple act of examination actually changes the sample before the research is completed. A case in point is the examination of biological samples under a microscope, where the radiant energy from the illumination can cause damage and even premature cell death. This problem, particularly noted with old-fashioned incandescent lamps, is effectively solved through the use of a fibre-optic cold light source.
By directing the visible light, without unwanted infra-red (heat) energy, sample illumination need no longer be a trade-off between being able to see the subject and being able to keep it alive. A steady colour temperature is another important consideration for the microscopist, so that delicate fluorescence effects are not altered by simply changing the brightness level of the illumination.
Cold light sources also offer advantages to the cost-conscious and environmentally-aware laboratory, promising long lamp life and low energy consumption with less maintenance requirement and lower power consumption.
