True Color LED illumination is a durable, bright light source with spectral properties that closely match halogen illumination. Olympus’ market-leading LED technology delivers accurate color reproduction that provides the confidence needed for reliable diagnoses in pathology.
Halogen illumination has for many years been the gold standard in microscope illumination. The main reason is that thanks to its particular properties, excellent color reproduction – both through the oculars and on the computer screen – can be obtained.
Today, LED technology has become a viable alternative for conventional lighting in many areas of everyday life. Its bright, efficient light output provides many benefits across different industries. However, in the field of microscopy, where incorrect color reproduction can impact the evaluation of a sample, LED technology shows its shortcomings, often introducing undesired color shifts. So, what could make an LED suitable for the rigorous demands of clinical microscopy?
Measuring the Quality of a Light Source
An LED light source for microscopy should emit white light, but should also be able to match or even surpass the capability of halogen light to show the colors of the sample correctly. How has the halogen light source up until now been able to perform well at this task? It turns out that the key is its mostly even intensity across the visible spectrum, which allows uniform illumination of all the different colors in a sample.
