The rest of the fluorophores which are not activated cannot be excited to fluorescence by the excitation wavelength.

The latter are readily water-soluble compounds which can easily be oxidised to resorufin compounds, which display a readily measurable absorption in the visible range and, furthermore, can easily be stimulated to fluoresce.

Upon illuminating the indicator area with AF illuminating light, a part of the illuminating light (its long-wave portion) will fall through the indicator filter onto the fluorescent surface below and will excite this surface to fluorescence.

The dyes which are used in fluorescence microscopy react on specific excitation wavelengths and deactivation wavelengths allowing to excite fluorescence or to deactivate fluorescence specifically well.

By exciting, an image point of a specific size can be excited to emit fluorescent light, while immediately thereafter around the center of excitation a deactivation can be applied, allowing to narrow down the fluorescent light emitted from this image point of the object 2 to a small image point and therefore allowing to increase the resolution.

On account of its longer wavelength, the emitted fluorescent light cannot excite any further fluorescent particles in the eye model to produce fluorescence.

The filter wheel 94 has a pinhole diaphragm 96 d and illumination filter (96 a, 96 b, 96 c), by means of which it is possible to set the spectral composition of the illumination light in such a way that the dye ICG or 5-ALA or NaFl can be excited therewith to fluoresce and the light with a wavelength corresponding to the wavelength of the fluorescence light of these dyes being filtered in the process.

With the arrangement shown in FIG. 3 e.g. fluorescent spectroscopy can be carried out, in which the excitation beams 146 excite local fluorescence of a sample 158 .

With 266 nm (Nd:Yag) or 248 nm (KrF-Eximer) small aromatics such as benzene, toluene and xylol (BTX) or phenols as well as larger polycyclic aromatics (PAK) can be excited to fluorescence.

Further analysis of these bands can take place, for example, in scanners which excite the fluorescent label at a given wavelength, depending on the fluorescent label employed in each case, and/or scanners which are able to detect the light which is emitted in association with the chemical transformation of a chemiluminescent substrate.

In the case of photoluminescence or fluorescence, the excitation is carried out by absorption of photons.

The sample is evaluated by determining the fluorescence after exciting the fluorescent labelling groups.

The fluorescence under UV stimulation is clearly visible macroscopically as well as in a fluorescence microscope.

Berkelium(III) phosphate (BkPO4) has been prepared as a solid, which shows strong fluorescence under excitation with a green light.

With progressive formation of cataracts, i.e. increasing discoloration, the fluorescence with longer wave excitation sets in gradually and then increases more strongly than that with short wave excitation.

The UV A flurorescence has a stimulating effect, while the UV B (Dorno radiation) reddens the skin and has an anti-rachitic effect.

The cleavage of the fluorogenic substrate is measured by fluorescence spectroscopy (excitation and emission wavelength at 280 and 350 nm respectively).

To do this, the DNA can be fractionated by electrophoresis, then stained with ethidium bromide and finally detected by fluorescence using UV excitation.

After an incubation time of 30 min at 22° C., fluorescence is measured (excitation: 360 nm, emission: 460 nm).
