  1. Remove the dust cover from the microscope
  2. Turn on the computer (#1)
  3. Turn on the X-Cite exacte lamp on the shelf to the left of the microscope (#2)

    The X-Cite exact lamp display will flash during heating (approximately 4 minutes) and will then be operational.

    The exact X-Cite lamp must be turned on for at least 30 minutes before being turned off and vice versa

  4. Turn on the power bar on the shelf above the computer (#3)

  5. Press the microscope start button located on the rear left of the microscope (#4)

  6. Use your UdM credentials to log in to Windows

    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-Imager Z2
  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 = 11 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 = 11 mm). 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 20x objective is the best Air objective because it has the greatest number of optical corrections (Plan Apochromat) and the largest numerical aperture (0.8). 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!

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 software Zen Blue
  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, clean oil lenses with lens cleaner and paper
  5. Turn off the power bar on the shelf above the computer (#3)

  6. Turn off the X-Cite exacte lamp (#2)

    The X-Cite lamp must be on for at least 30 min before being turned off and vice-versa

  7. Turn off the computer
  8. Cover the microscope

Important Reminders

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

The following diagrams allow you to follow the light path in transmitted light (bright field, DIC) and in reflected light (fluorescence).

  • Quality control for Illumination, Liquid light guide and filters quality.
  • Camera sensor clean up

new Transmitted Light module

The previous halogen lamp has been replaced with an LED.

Some acquisition setup might need to be adjusted accordingly.

=> If no signal visible, please try to increase illumination voltage for the TL modes (BF, DIC, Phase, Darkfield) 


  • Cy5 channel was misaligned with TXR & Cy3: switched Cy5 & Cy3.5n fllter cubes positions (7 ↔  8). Cy5 (blue signal) was shifted in y relative to TXR and AF555 channels (left), and appears to colocalize after cube slot switch (right):

Please advise platform managers if other channels appear misaligned.

Troubleshooting

The best way to solve a problem in Microscopy is to follow the light path. You will find in the Light path tab of this page, the diagrams which will allow you to follow the light all along its path through the microscope.

  1. Open the light path file
  2. Starting from the light source and moving towards the detector, verify that there is indeed light after each component of the microscope

Vignetting

reflects the fact that the field of view (hence final picture) is not completely homogeneous due to the optic parts within the microscope.

The high-resolution sCMOS camera mounted on the Z2-upright microscope has a sensor chip larger than what the optics can allow; hence the significant vignetting when using the full chip of the camera (2048x2048):

It is thus recommended to only use the 1024x1024 pixels at the center of the camera chip (pink square):

This can be defined in the acquisition parameters in Zen Blue.

FAQ

No. It is an upright microscope designed for the observation of specimens between a slide and a coverslip (thickness 0.17mm).
