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. |
- Start the Zen Blue software
|
UI Expand |
---|
| - If open, close the Zen Blue software and wait for it to close completely (up to 30 seconds)
- On the Desktop open the Documentation folder
- Double-click Settings for Axio-Observer Z1
- A script will run and a black window will appear briefly
- You can then reopen the Zen Blue software

title | Focus Calibration Z |
---|
| On the microscope touch screen: - Press Home>Load Position to lower the stage to its lowest position
- Press Set Work Position to store this position
- If necessary, move the focus slightly up to remove the "Lower Z limit reached" message displayed on the touchscreen
- Press Home>Microscope>Turret>Objectives>10x to select the 10x objective
- If asked, tap Done to remove the oil lens cleaning warning
- Press Home>Microscope>XYZ>Position>Z-Position>Set zero>Auto to perform focus calibration
- Press OK to start the focus calibration procedure
- Wait a few seconds for the calibration to be completed
Once calibrated, the focus can be found at Z = 5 mm). The Z value can be found on the microscope touch screen Home>Z-Position |
UI Expand |
---|
| Remarque |
---|
Make sure to calibrate the focus before performing the first focus. |
On the microscope touch screen: - Press Home>Microscope>Turret>Objectives
- Press 10x to select the 10x lens
Info |
---|
| 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. |
- Press Home>Load Position to lower the stage to its lowest position
- Press Set Work Position to store this position
- If necessary, move the focus slightly up to remove the "Lower Z limit reached" message displayed on the touchscreen
- Place the test slide on the microscope stage with the coverslip toward the objective
Remarque |
---|
Always use the test slide to perform the first focus. |
- If necessary, move the stage so that the sample is centered on the objective
On the computer: - Open the Zen Blue software
- In the Locate tab, select BF or the desired fluorescence ((CFP/GFP/DsRed ou GFP/RFP/Cy5, etc…) to activate the configuration
- 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 = 5 mm). The Z value can be found on the microscope touch screen Home>Z-Position In the Locate tab, select Off to turn off the illumination UI Expand |
---|
| Remarque |
---|
Important: First focus with the safest lens (10x) before selecting another lens and continuing with secondary focus (see section "Primary Focus" above). |

| Info |
---|
title | no Air Objectives on this instrument |
---|
| This microscope only has a 10x air objective (see section "Primary Focus" above). However, if there were other, higher magnification objectives requiring air as a media, the procedure would be as follows: |
After performing the first focus, on the microscope touch screen: - Press Home>Microscope>Turret>Objectives
- Press on the desired lens
In Zen Blue software: - In the Locate tab, select BF or the desired fluorescence (CFP/GFP/DsRed ou GFP/RFP/Cy5, etc…) to activate the configuration
- Adjust the focus with the precision dial while looking through the eyepieces until the image is perfectly sharp
- In the Locate tab, select Off to turn the illumination off
- Your sample is ready for acquisition!

title | Focusing with oil objectives |
---|
| After performing the first focus, on the microscope touch screen: - Press Home>Microscope>Turret>Objectives
2. Press 63x Oil (1.4) or 100x Oil (1.4) to select the desired lens. The microscope will automatically lower the stage so that the sample is accessible. Info |
---|
The 63x objective is a very good objective because it has the a good transmittance and a larger field of view than the 100x. Given the pixel size of the camera, Nyquist sampling can reach the resolution limit when using the 1.6x tubelens. |
- Remove your sample from the microscope
- Place a drop of oil on the objective
- Replace your sample from the microscope
- Press Done. The microscope will automatically return the sample to its original position
In Zen Blue software: - In the Locate tab, select BF or the desired fluorescence (CFP/GFP/DsRed ou GFP/RFP/Cy5, etc…) to activate the configuration
- Adjust the focus with the precision dial while looking through the eyepieces until the image is perfectly sharp
- In the Locate tab, select Off to turn the illumination off

| Remarque |
---|
| - During an acquisition session, files can be saved temporarily 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 at the end of your session. |
- Save your data
- Close the software Zen Blue
- Transfer your data to the D: drive (Data Storage) or to your external drive and delete it from the local C: drive
- If used, turn of the incubation power bar
- If used, clean oil lenses with lens cleaner and paper
- Turn off the microscope power bar on the right of the microscope (#3)
- Turn off the camera and laser power bar on the left of the microscope (#2)
- Turn off the computer
Remarque |
---|
| - Take back your samples including those inside the microscope chamber
- Leave the microscope and the working area clean
