User Guide

  1. If not already done, turn on the computer (#1) and log in to Windows using your UdeM credentials
  2. Remove the dust cover from the microscope
  3. If incubation is required, turn on the incubation power bar (#2) on the desk near the computer and open the CO₂ cylinder (#2B) near the sink

    Make sure the humidifier is properly filled with distilled water.

  4. Turn on the microscope power bar (#3) on the desk near the computer

  5. When using the instrument for the first time, it is necessary to import the microscope configuration before starting the software. See the First Use section below.
  6. Start Zen

When using the instrument for the first time, it is necessary to import the microscope configuration into the software. This procedure is usually carried out during the training session. However, it can also be used to reset the software if it does not display correctly, for example. Running this procedure will erase all your experiment protocols and reset the software to its original settings (ask for support if you are not sure).

  1. If Zen is open, close it and wait until it has completely shut down (this may take up to 30 seconds)

  2. On the Desktop, open the Softwares folder

  3. Double-click Zen Settings for Zeiss Z1-Colibri

  4. A script will run and a black window will appear briefly

  5. When the message Settings for Zen have been imported successfully appears, click OK to close it

  6. You can now open Zen

During this procedure, you will:

  • Set the microscope to a safe configuration
  • Perform a calibration
  • Load your sample
  • Find and adjust the focus

Once completed, your sample will be ready for acquisition.

This step is required to calibrate the microscope in XY and Z. Performing this calibration will significantly reduce the time needed to locate and focus on your sample.

  • If not already done, select the lowest-magnification objective. On the microscope touch screen Home > Microscope > Control > Objectives > 2.5x
  • In Zen, once it has started a calibration dialog should appear. Simply click Calibrate Now.
    The microscope will lower the objectives, perform an XY calibration first, followed by a Z calibration, and then return to its original position.

Once calibrated, the focus is typically found at Z = 1.1 mm for a microscope slide. For a multi-well plate the focus is generally around Z = 3 mm but this is highly dependent on your multi-well plate.
The Z position can be viewed on the microscope touch screen under Home > Z-Position, as well as in Zen within the Focus tab, located on the right side of the screen.

The system may already be calibrated. This can occur if a previous user calibrated the system and left it on.

In Zen, within the Focus tab, located on the right side of the screen:

  1. Click Load to lower the objective

  2. The Z position is indicated below Current
  3. If Z position value is less than 100 um the system is calibrated

On the microscope touch screen:

  1. Lower the objective by pressing Home > Load Position

  2. Press Set Work Position to store this position

  3. If necessary, slightly adjust the focus upward to clear the Lower Z Limit Reached message displayed on the touch screen

  4. The Z position value is indicated
  5. If the value is less than 0.1 mm then the system is calibrated

In Zen, within the Stage tab, located on the right side of the screen:

  1. If not already done, check the Show All option
  2. At the bottom of the tab click Calibrate

  3. A warning message will show up click Continue

  4. The microscope will lower the objectives and perform a XY stage calibration and then return to its original position.

In Zen, within the Focus tab, located on the right side of the screen:

  1. If not already done, check the Show All option
  2. At the bottom of the tab click Calibrate

  3. A warning message will show up click Continue

  4. The microscope will then perform a Z calibration and then return to its original position

XY and Z calibrations are now complete

On the microscope touch screen:

  1. Navigate to Home > Microscope > XYZ > Position > Z-Position > Set Zero > Auto to perform focus calibration

  2. Press OK to start the calibration procedure

  3. Wait a few seconds for the calibration to complete

  4. Lower the objective by pressing Home > Load Position

  5. Press Set Work Position to store this position

  6. If necessary, slightly adjust the focus upward to clear the Lower Z Limit Reached message displayed on the touch screen

  7. Navigate to Home > Microscope > XYZ > Position > XY-Position > Set Zero > Auto to perform a stage calibration

  8. Press OK to start the calibration procedure

  9. Wait a few seconds for the calibration to complete

XY and Z calibrations are now complete

In Zen:

  1. In the menu bar, navigate to Tools > Options

  2. Select Startup/Shutdown

  3. Under Stage/Focus Calibration, ensure Request Stage/Focus Calibration on Startup is checked

  4. Click OK to close the Options dialog

Important

Ensure that the calibration has been completed beforehand. Calibration will significantly reduce the time required to locate and focus on your sample.

On the microscope touch screen:

  1. If not already done, select the lowest-magnification objective Home > Microscope > Control > Objectives > 2.5x

The 2.5× and 10× objectives are the safest to use due to their long working distance (>6 mm). The sample will appear in sharp focus well before the objective approaches it. It is recommended to always focus using the safest objectives first. Since the objectives are parafocal, focusing with the safest objectives will facilitate locating the sample when switching to higher-magnification objectives.

  1. Lower the objective by pressing Home > Load Position

  2. Press Set Work Position to store this position

  3. If necessary, slightly adjust the focus upward to clear the Lower Z Limit Reached message displayed on the touch screen

  4. Place the test slide on the microscope stage with the coverslip facing the objective

    Important

    Using a test slide will significantly reduce the time required to set up the instrument.

  5. If necessary, adjust the stage to ensure that the sample is centred under the objective

In Zen:

  1. In the Locate tab, select BF or the desired fluorescence (Fluo, DAPI, GFP, Cy3, Cy5) to activate the configuration
  2. Adjust the focus with the main dial while looking through the eyepieces until the image is perfectly sharp

Once calibrated, the focus is typically found at Z = 1.1 mm for a microscope slide. For a multi-well plate the focus is generally around Z = 3 mm but this is highly dependent on your multi-well plate.
The Z position can be viewed on the microscope touch screen under Home > Z-Position, as well as in Zen within the Focus tab, located on the right side of the screen.

  1. In the Locate tab, select Off to turn off the illumination

Important

Perform the initial focus using the safest objective before switching to higher-magnification objectives.

After performing the initial focus, on the microscope touch screen:

  1. Press Home>Microscope>Control>Objectives
  2. Press 10x, 20x40x or 63x (0.75) to select the desired objective
The 40x objective is the best Air objective because it has the largest Numerical aperture (0.75) together with a wider field of view (40x).

In Zen:

  1. In the Locate tab, select BF or the desired fluorescence (Fluo, DAPI, GFP, Cy3, DsRed, Cy5) to activate the configuration
  2. Adjust the focus with the precision dial while looking through the eyepieces until the image is perfectly sharp
  3. In the Locate tab, select Off to turn off the illumination

Your sample is ready for acquisition!

After performing the initial focus, on the microscope touch screen:

  1. Press Home>Microscope>Turret>Objectives
  2. Press 63x Oil (1.4) to select the desired objective. The microscope will automatically lower the stage so that the sample becomes accessible.

  3. Place a single drop of oil on the objective
  4. Press Done. The microscope will automatically return the objective to its original position

In Zen :

  1. In the Locate tab, select BF or the desired fluorescence (Fluo, DAPI, GFP, Cy3, DsRed, Cy5) to activate the configuration
  2. Adjust the focus with the precision dial while looking through the eyepieces until the image is perfectly sharp
  3. In the Locate tab, select Off to turn off the illumination

  • Use a higher magnification objective

FAQ

Yes. This is an inverted microscope designed to look at specimen in a dish or a multi-well plate. The objectives are optimized to image through thin glass bottom multi-well plates. You may also image specimen mounted between a slide and a 0.17mm thick coverslip. For long timelapse, be aware of photo-toxicity.

Yes, but... This microscope has an incubation module to maintain temperature, humidity and gas. Yet it does not have a Definite focus which can maintain focus throughout time. Therefore, it is possible to loose the focus over long period. You can always do a software autofocus at different time but be aware of photo-toxicity if you are using fluorescence.

Extended Focus is a method to flatten a Z-stack by keeping only the relevant information.

In Zen:

  • Select the Processing Tab
  • Select the Extended Depth of Focus Method
  • Click Apply
  • Wait until the processing is finished
  • Save the processed image
