Using the Range Indicator
Remember, when acquiring your images, you
want to be within the dynamic range of the
detector. This is especially critical when
collecting images that will be used for
quantitative analysis.
•
Use the Range Indicator to adjust the gain
and offset.
Blue
= minimum,
Red
= maximum
(0 and 255 for 8 bit image, 0 and 4095 for 12
image, 0 and 65536 for 16 bit image.)
•
Adjust Detector Gain and Amplifier Offset to
remove red and blue pixels. Minimum should
be ~ 10-20 gray levels above 0 and Maximum
should be 10-20 gray levels below 255 for an
8 bit image. You can scale this accordingly for
12 and 16 bit images.
