  • Detector
    • Zeiss AxioCam MR R3 CCD Camera 1388 x 1040 pixels, 12-bit, 13 images/s at full resolution, detector size 8.9 mm x 6.7 mm

  1. Remove the dust cover from the microscope

  2. Turn on the computer (#1)

  3. If necessary, turn on the power bar for the incubation module (#2A) and open the CO2 cylinder (#2B)

  4. Turn on the power bar at the bak f the computer monitor (#2)

  5. Press the microscope start button located on the rear left of the microscope (#3)

  6. Log in Windows using your UdM credentials

    When using for the first time, it is necessary to import the microscope-specific parameters BEFORE starting the software. See the First Use section below.

  7. Start the Zen Blue software

When using for the first time, it is necessary to import the microscope-specific parameters into the software. This procedure is usually carried out during the training session. However, it is also possible to use it to reset the software if it is not displayed correctly, for example.

Please note, this procedure will delete all your experiment protocols and restore the software to its original settings.

  1. If open, close the Zen Blue software and wait for it to close completely (up to 30 seconds)
  2. On the Desktop open the Documentation folder
  3. Double-click Settings for Axio-Osberver Z1
  4. A script will run and a black window will appear briefly
  5. You can then reopen the Zen Blue software

This procedure puts the microscope in a safe configuration and performs a focus calibration. At the end of this procedure the microscope will be ready for acquisition.

On the microscope touch screen:

  1. Press Home>Load Position to lower the stage to its lowest position
  2. Press Set Work Position to store this position
  3. If necessary, move the focus slightly up to remove the “Lower Z limit reached” message displayed on the touchscreen
  4. Press Home>Microscope>Turret>Objectives>10x to select the 10x objective
  5. If asked, tap Done to remove the oil lens cleaning warning
  6. Press Home>Microscope>XYZ>Position>Z-Position>Set zero>Auto to perform focus calibration
  7. Press OK to start the focus calibration procedure
  8. Wait a few seconds for the calibration to be completed

Once calibrated, the focus can be found at Z = XX mm). The Z value can be found on the microscope touch screen Home>Z-Position

Important

Make sure to calibrate the focus before performing the first focus.

On the microscope touch screen:

  1. Press Home>Microscope>Turret>Objectives
  2. Press 10x to select the 10x lens

    The 10x objective is the safest because it has the longest working distance (5.3 mm). The sample will appear perfectly sharp long before the lens approaches it. It is recommended to always first focus with the safest lens. The objectives are para-focal, focusing with the safest objective will then allow you to easily find your sample with another objective.

  3. Press Home>Load Position to lower the stage to its lowest position
  4. Press Set Work Position to store this position
  5. If necessary, move the focus slightly up to remove the “Lower Z limit reached” message displayed on the touchscreen
  6. Place the test slide on the microscope stage with the coverslip toward the objective

    Important

    Always use the test slide to perform the first focus.

  7. If necessary, move the stage so that the sample is centered on the objective

On the computer:

  1. Open the Zen Blue software
  2. In the Locate tab, select BF or the desired fluorescence (GFP, DsRed, DAPI, etc…) to activate the configuration
  3. Adjust the focus with the main dial while looking through the eyepieces until the image is perfectly sharp

    Once calibrated, the focus can be found at Z =  XXmm). The Z value can be found on the microscope touch screen Home>Z-Position


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

Important

First focus with the safest lens before selecting another lens and continuing with secondary focus.

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

  1. Press Home>Microscope>Turret>Objectives
  2. Press 20x or 40x to select the desired lens

    The 40x objective is the best Air objective because it has the greatest number of optical corrections (Plan Apochromat) and the largest numerical aperture (0.95). It offers a lateral resolution of 420nm at a wavelength of 550nm.


  3. Adjust the focus with the precision dial while looking through the eyepieces until the image is perfectly sharp
  4. Your sample is ready for acquisition!

This microscope does not have oil immersion objectives. However, if there were, the procedure would be as follows:

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

  1. Press Home>Microscope>Turret>Objectives

  2. Press 63x Oil, 100x Oil (1.3) ou 100x Oil (1.4) to select the desired lens. The microscope will automatically lower the stage so that the sample is accessible.

    The 63x objective is the best oil objective because it has the most optical corrections (Plan Apochromat) and the largest numerical aperture (1.4). It offers a lateral resolution of 240nm at a wavelength of 550nm.

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

In Zen Blue software:

  1. In the Locate tab, select BF or the desired fluorescence (GFP, DsRed, DAPI, etc…) 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 the illumination off
  4. Your sample is ready for acquisition!
  • Files can be saved temporarily (during acquisition) on the local C: drive (desktop)
  • At the end of each session, copy your data to your external drive and delete it from the local C: drive
  • You can store your files on the D: drive (Data Storage). If you do, please create a folder per laboratory using the principal investigator last name. Within, create one folder per user (Firstname_Lastname).

In any case, your files should be removed from the C: drive.

  1. Save your data
  2. Close the Zen Blue software
  3. Transfer your data to the D: drive (Data Storage) or to your external drive and delete it from the local C: drive

  4. If used, turn off the incubation module power strip (#2A) and close the CO2 cylinder (#2B)

  5. Turn off the microscope power bar (#2)

  6. Turn off the computer
  7. Cover the instrument with the protective dust cover

Important Reminders

  • Take back your samples including ones in the microscope
  • Leave the microscope and the working area clean

The following schematics depict the light path for transmitted (bright-field and Phase Contrast) and reflected (fluorescence) lights.

Troubleshooting

This microscope is motorized for most of its components, yet the X-Cite light source is manual. Ensure the X-Cite diaphragm (#4B) fully opened (high position).

  1. On the X-Cite lamp
  2. Turn the intensity diaphragm (#4B) up

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.
