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.H-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 Sensitivity and Ultra Sensitivity
High Sensitivity and Ultra Sensitivity are different camera modes. In Ultra Sensitivity
mode, the Fluor-S MAX camera is cooled to –35.0 degrees C. In High Sensitivity
mode, the camera is cooled to –20.0 degrees C. The current camera temperature is
displayed at the bottom of the acquisition window.
Fig.H-6. Camera Temperature display.
High Sensitivity is the normal operating mode of the Fluor-S MAX. Ultra 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.
Note: When you change from High to Ultra Sensitivity or visa versa, there will be a
delay of several minutes while the Fluor-S MAX camera cools down or warms
up. If you attempt to acquire an image during this period, you will be notified of
the changing temperature. If you do not want to wait, you can cancel the mode
change.
