ABSTRACT:
An illumination device permitting microscopes, for use of the microscope as a fluorescence microscope, comprises a light-screening tube (2, 4) preferably of variable length, one end of the tube being connectible to the microscope objective and the other end being disposed to surround the sample which is intended for microscopic observation on the sample stage (1) of the microscope. An opening in the tube is arranged to direct high intensity UV and/or visible light towards the sample. In that the light is directed towards the sample bypassing the optics of the microscope, substantially unchanged light intensity will be realized from the light source to the sample, which considerably facilitates fluorescence studies with, in particular, microscope objectives of low magnifying power and low numerical aperture.
