200 Luminescence System consists of the following parts:
 Luminescence Optics
 Detection Unit (Basic or Standard PMT)
Figure 5-13: Optical System Luminescence
The luminescence fiber bundle guides the light from the sample to the detection
unit (PMT) passing a filter wheel. The PMT (photomultiplier tube) is designed for
applications in chemo- and bioluminescence providing a high dynamic range. The
exceptional low noise and high sensitivity allows the detection of very low light
levels.
The z-position of the luminescence fiber bundle fixed onto the optics carrier is
adjusted automatically by the software and depends on the selected plate
definition file. As light is refracted at the sample liquid surface, z-adjustment helps
to maximize signal to noise and minimize cross-talk.
