Enter a name for your application in the Name field.
Next, click on the buttons next to the Filter, Illumination, Gain and Binning fields to
change these settings.
Note: Note that if you select trans white illumination, you will need to place the white
light conversion screen on the sample stage.
A higher Binning setting (2x2, 3x3) provides optimal sensitivity for low-light
applications such as chemiluminescence. In this mode, the pixels in the camera are
“binned” (e.g., four pixels are combined into one) to increase the amount of signal per
pixel without increasing noise. Note that combining the pixels results in a reduction in
the resolution of the image.
Selecting a higher Gain (4x) provides higher sensitivity without reduced resolution;
however, noise will also increase. This is useful for faint signals (bright spots will
saturate). Selecting a lower gain (0.5x) is useful for brighter images that tend to
saturate. A gain setting of 1x provides the greatest dynamic range.
Click OK to implement your changes.
After you have created an application, you can select it from the application tree by
selecting Custom and the name you created.
