6. Accessories
6.1. CCD
1. CCD camera is used to observe the inside of the specimen chamber, mainly used to monitor the
position of the sample, convenient for workers to operate, while avoiding the damage to the sample
or the pole shoe caused by misoperation.
2. To open the CCD function, click the [CCD] button on panel; to close the CCD, just close the pop-
up window.
3. Note: Since the photons emitted by the infrared lamp of the CCD camera will saturate the diode
of the backscatter probe, if the backscatter detector is used to observe the sample, the CCD function
will automatically turn off when the dual-channel acquisition is turned on, i.e. the [Dual] button on
the shortcut toolbar is clicked.
4. Note: Since the photons emitted by the infrared lamp of the CCD camera will also affect the Energy
Dispersive spectrometer analysis, when equipped with the energy spectrum detector, if the CCD is
turned on, the interface will pop up as shown in the dialog box. Select "Yes" to open the CCD function;
choose "No", do not turn on the CCD function. If you use the spectrum after opening the CCD
function, you need to manually close the CCD window.
6.2. Backscatter detector
1. The front panel knob and key of the backscatter detector main amplifier are illustrated below
Knob / Key Description
Power Power switch.
Contrast Coarse Image contrast coarse adjust, usually placed in X50 gear.
Select Select A or B channel, A+B uses shadows to create strong
topographical and atomic number contrast, A-B is the pseudo-
topographical image with suppressed atomic number contrast and
maximum topographical contrast.
Contrast Fine Image contrast fine adjust
Brightness Image brightness adjust
