For biological and medical research fluorescence micrscopes are used to visulaize certain parts of living cells and tissues with help of fluorphores
One or more fluophores are added to the specimen which needs to be researched and attach to certain tissue parts like proteins. When exposed to short-wavelength light (exicitation light) fluorphores light up (emission light). With this one can distinguish for example tumor cells from other cells, seperate cells, prove the presence or absence of antibodies, etc
The Euromex fluorescence microscope is constructed with an incedent mercury vapor light source, special Plan Fluarex semi-apochramatic objectives, a set of excitation and emission filters and a semi-transparant mirror. The translucent light source is a modern 3 Watt illuminator

Binocular microscope with Plan Semi-APO 4x, 10x, S40x Fluarex objectives, 3 Watt LED illumination and a 100 Watt Mercury fluorescence epi-illumination.
