1. Check the booking system to see if anyone is booked on the system within the next hour. If not shutdown. 2. Select Configuration>Laser and drop the Argon slider back to standby 3. Close the LAS-AF program and shut down the PC 4.
Mounting

Ensure the correct stage insert is mounted (see facility staff if unsure) Remember to invert your slide so that the cover glass is the closest surface to the lens Select the objective lens either using the two buttons behind the right focus wheel or in the software within the Acquire tab then select the Objective text to see a drop down list of lenses Use the joystick to move the stage if necessary.
zero. Pressing the lower Z set button drops the lens to its lowest position. This is useful when you want to change to a different cover glass on the same slide if you’re using an oil immersion lens. Dropping the lens is always good practice when changing slides too.

1. From the left hand margin of the screen under Acquisition Mode select the Seq button to open the sequential mode window 2. Select the + button which will add a scan. Each scan corresponds to a single laser/detector combination.
Acquisition Settings 1. Select the XY window in the left hand margin 2. Format changes the size of the image in pixels. For better xy sampling choose 1024x1024. For speed choose 512x512. 3. Speed determines how long the laser spot dwells over any particular part of the sample.
Save All option at the bottom of the experiment window. 5. Images are stored as Leica LIF format by default which can be opened with FIJI’s Bio-Formats plugin.

1. Adjust scan parameters as for 2D image capture. 2. When optimising the image intensity for a z stack, move through focus while live scanning to find the focal plane with the highest signal intensity.
