Scan Dimension
If an application uses trans illumination, the Scan Dimension buttons become
active. The scan dimension is the distance traveled by the transilluminating
light source as it scans horizontally across the platen.
Fig. 8-5. Scan dimension settings for trans illumination.
The full scanning range is 300 mm. Select a smaller range if your sample is
small and you do not want to wait while the light source travels over the
maximum scan width.
High Resolution Versus High Sensitivity
High Resolution and High Sensitivity are mutually exclusive options. High
Resolution is the normal operating mode for the Fluor-S. High Sensitivity
provides optimal sensitivity for low-light applications. It is the default
selection for the chemiluminescence application, and may be selected for a
custom application.
In High Resolution mode, images are captured at the maximum resolution of
the camera.
In High Sensitivity mode, the pixels in the camera are “binned” (i.e., four
pixels are combined into one) to increase the amount of signal per pixel.
However, combining the pixels results in a reduction in the resolution of the
image.
8.3 Step II. Position/Focus
Note: When you click on the Position or Focus button, the light inside the
Fluor-S box automatically turns on. To turn the light off while positioning
or focusing, hold down the SHIFT key when clicking on the button.
