Click the Configure button on the
AX Pad panel to display the settings window. There are several tabs:
Sets the preferred scan direction. Unidirectional scan or
bidirectional scan is available for each scanner. The bidirectional mode is faster but needs to be aligned properly in the Alignment tab.
Caution
In Galvano mode, bidirectional scanning is reserved for resolutions 1024 x 1024 and smaller. You can select the bidirectional mode here, but when higher resolutions will be set, the scanner will switch to a unidirectional mode automatically.
Select the noise-reduction method and the range of frames which will be available in the AX Pad panel.
The automatic number of lines is 512 for all line lengths. De-select this option to set the size manually.
This value is used with the Acquire > Capture command.
This value is used in ND Acquisition experiments.
In this mode, the Find mode acquisition parameters are calculated to achieve the fastest possible frame rate. A pre-trained AI network is used to enhance the low-resolution live image. A well aligned bi-directional mode is recommended.
Optionally, you can set the find-mode parameters manually. In this mode, no image enhancement is applied.
Use bi-directional scanning mode.
Frame rate can be increased by skipping lines. Line skipping 2x scans every second line, line skipping 4x scans every fourth line.
If this option is displayed, your laser unit is equipped with a controllable mechanical shutter.
A mirror is used to redirect the lasers out of the optical path when the device is idle. Minor intensities could reach the sample in this mode even though.
Choose this option to prevent any light to reach the sample during idle phases of work.
This option allows you to acquire images with their brightness unchanged even if the Pixel Dwell Time is changed. It works only with the galvano scanner type.
This function uses a gamma curve to lighten dark areas of the image. This option is only applied if the High Dynamic Range option is selected.
The original (wider) dynamic range of the detectors is re-calculated to the 12-bit range of the resulting images. With this option ON, the whole range of the detector is used, otherwise, the range is slightly cropped.
Hides sliders in the AX Pad panel and applies the offset values specified here. Different offsets can be specified for galvano/resonant modes and the TD channel.
If selected, channels cannot be turned ON/OFF arbitrarily in the AX Pad panel.
Detector gains can be controlled automatically during stimulation experiments in order to handle the case when a PMT overload occurs.
Sets the gain on all detectors to 0 during stimulation. The original gain is restored after stimulation. PMT overload cannot occur.
The automatic gain control is turned OFF - the gain remains unchanged. If PMT overload occurs, a red alert appears in the AX Pad panel. The user must adjust the gain manually to restart the detector.
The gain remains unchanged. A PMT overload can occur, but the detector is recovered automatically after the stimulation.
Hides the AX Scan Area panel. Does not apply any correction.
Displays the AX Scan Area panel.
When bidirectional scan mode is selected in the Acquisition tab, a shift between even and odd lines may occur in the image. You can correct the shift here.
Only the active scanner can be aligned, if the buttons are disabled, close the window and activate the other scanner in the AX Pad panel.

Starts scanning and displays the live image window. You can check influence of the alignment.



Runs a dedicated algorithm which calculates the pixel gap automatically based on a series of captured images. Make sure the sample for automatic alignment has distinct texture and minimum noise.
Note
The galvano scanner enables rotation of the scan area. Therefore alignment of the Y direction is performed with the scan area rotated by 90 degrees.
You can adjust the pixel gap manually. Either drag the slider by mouse or type a value to the edit field on the right.
Determines behavior of the AX Scan Area panel is pressed:
The scan size remains unchanged and the Zoom Size value is adjusted automatically.
The Zoom Size remains unchanged and the scan size (image resolution) is adjusted automatically. The resolution which provides the closest value of the pixel size to the Nyquist resolution will be selected.
Select how the suggested Z-step value is computed in the ND Acquisition Z series settings window.
It is computed as a ratio of the optical section thickness (optical section thickness = FWHM of the Z airy disc).
Select a wavelength from which the AU is calculated.
One of the lasers used in the experiment will be used.
Sets a default position for the pinhole. This pinhole position is set by the button in the AX Pad panel.
Sets a user-defined pinhole position and displays an additional shortcut-button in the AX Pad panel. If the value is 0, no button will be displayed.
The pinhole position can be aligned by manually shifting the condensing lens.
