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. 9-5. 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. 9-6. 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.
