– For biological and medical applications fluorescence microscopes are used to observe certain parts of living cells and tissues with help of fluorophores.

-One or more fluophores are added to the parts of the specimen to be observed.

-When the fluorophores are exposed to so-called exicitation light, the excitation energy is absorbed by the fluorophore that start emitting so-called emission light that can be observed by the microscope.

-One can distinguish tumor cells from other cells, follow biological processes or prove the presence or absence of antibodies, etc

– The Oxion microscopes for fluorescence are equipped with an epi-illumination with a 100 W mercury vapor lamp.

-The fluorescence attachment have a rail for maximum 4 filter cubes.

-The FluoLed model is equipped with a 455 nm LED and one filter cube, especially developed for efficient and fast detection of tuberculosis by the Auramine-O fluorochrome.

-Other FluoLED wavelengths are also available.
