5.3.7 Fluorescence Illumination
The built in halogen light source together with the filter slider creat the excitation light for
flourescence measurements. The light is guided into the dark box using a 4 fold fibreoptic
gooseneck (1). The fibres can be modified by hand in order to offer the best possible illumina-
tion.
For additional illumination devices such as a double goose neck (see 10.1.6) or the line light
(see 10.1.5) an auxiliary light output port (2) is located at the right side at the ceiling of the dark
box.
When the ring is in the lower position, the light is guided to the 4 fibre optic light guides. When
pulling the ring to the upper side an optical switch guides the light to the auxiliary light output
port. The light guide is fixed in the socket by spring loaded balls . To remove it pull the light
guide slightly.
