Select
to define the measurement workflow.
Four different kinds of meaurements can be performed. Please note that depending on the sys-
tem configuration some of the selections might not be possible (e.g. due to a missing fluores-
cence module).
Exposure Time
is the time when the CCD chip is exposed to the sample
Gain
is an internal conversion factor. Low Gain offers high dynamic range while high gain
gives higher intensity numbers but limited dynamic range.
Read out
defines the speed to read out the camera. High speed is recommended for
phgotographioc images, high intensity measurements of fluorescence images since a
higher background noise will be obtained. Low speed is ideal for highest sensitivity lu-
minescence measurements but trhe camera readout can take up to 15 seconds.
Binning Factor
is the combination of neighbouring CCD pixels during readout. The result is an in-
creased signal and thus an improved sensitivity and a better signal-to-noise ratio, how-
ever, at the cost of loss in spatial resolution.
