Live/Smart Live

Displays the live camera image according to the camera settings (the button changes to Freeze when the live image is shown). There are two types of live:

• Live - standard live signal form the camera

• Smart Live - works only on Fluorescence experiments. It checks the hardware status, including stage movement and changes in the light power. If there are no changes detected, the system automatically captures all experiment channels and deactivates the light. This ensures the convenient access to a multichannel live image without causing bleaching to the sample.

The Smart Live function can be enabled in the Configure... menu.

Capture

Acquires a single image from the camera.

Short/Long range Auto Focus

Performs auto focus by the selected motion method, detection method (criterion) and range. Motion is selected as the fastest supported motion. The criterion for detection is dynamically adjusted based on the fluorescence or brightfield modality being used:

• Brightfield Criterion - suitable for brightfield samples. Brightfield auto focus works based on the values set in Devices > Service Settings .

• Cells.ai Criterion - AI algorithm suitable for focus detection on cell samples, typically well plates.

To switch between the criterions, use the context menu over the Auto Focus button to if Enable Context Menus is checked in the Configure... menu or switch it directly in the menu.

Performing the long range focus can be done manually by Shift + clicking on the Auto Focus button or in the context menu over the button (Auto Focus Long).

Note

The Z lens piezo in the system functions with the auto focus only when the register key (HKEY_LOCAL_MACHINE\SOFTWARE\Laboratory Imaging\Misc\DeviceManagerv2\NosepiecePositionForObjectivePiezo) indicates the nosepiece position where the lens piezo is installed and when it aligns with the current nosepiece position. Please create the registry key “NosepiecePositionForObjectivePiezo” as “DWORD(32bit)”. Set the value in hexadecimal, Position #1 = “0”, Position #2 = “1” ... Position #6 = “5”.

Autosignal

Automatically finds the optimal camera exposure and light power using an AI algorithm. Autosignal.ai has two options for different algorithm strategies:

• Live Sample - tries to be more sensitive to the sample, e.g. by limiting the maximum light power.

• Fixed Sample - prefers to use more light with short exposures.

To switch between Live Sample and Fixed Sample algorithm, go to the Configure... menu.

Auto All

Performs Auto Focus and Autosignal in one operation on all channels.

ND Acquire

• Define/Run ND Acquisition - opens the standard ND Acquisition window (Combined ND Acquisition),

• Define/Run ND Acquisition Wizard - runs the ??? command used for a step by step ND acquisition.

The selected acquisition type is opened by clicking on the ND Acquire button itself. Switch between the two acquisitions using the the secondary mouse button over the ND Acquire button if Enable Context Menus is checked in the Configure... menu or switch it directly in the menu.
