UVITEC – Cambridge
53/225
The factory settings include 3 pre-defined Application protocols:
-
SafeLight
-
UV fluorescence
-
Conversion screen
You can also create or select your own Application protocol. Please refer to the Application protocol
chapter of this manual to have more details on the way you can create your own Application.
2- Click on Start Exposure.
The Serial exposure mode allows you to acquire a user defined number of image (frame). This set of
frame defines a video sequence. Each image has an exposure time. The software will wait a user-
defined time elapse prior to acquire the subsequent image.
The number of images defines the number of frame of the Serial exposure sequence.
The number of number of images, the exposure time, the time elapse and other Serial exposure
parameters are defined in the Application protocol or could be directly accessed from the Set-up
menu. For a complete detail of the set-up parameters, please refer to the Application protocol chapter
of this manual to have more details on each option.
Note: When the specified exposure time is reached, the last captured image is displayed. The camera
continues to integrate the image on the CCD sensor, updating the display whenever the specified
Exposure time is reached. The Stop exposure button stops the exposure process. The last full
exposure is displayed.
Preview
You can also preview your sample using the preview function (live mode):
Live mode allows direct visualization of the image. This mode enables you to adjust the aperture and
the focus, and to position your sample.
Note: A live image means the image displayed is refreshed every 1/20th of a second. This short
exposure time (or frame) is adequate for a variety of white light samples including protein gels and
autoradiography. A live image, however, is not sufficient for most samples, which are visualized and
photographed over a relatively dim UV light source. A feature called integration compensates the low
light situation by allowing the CCD camera to obtain a timed exposure.
Note: After 2 minutes, the software will automatically stop the live preview.
