Apotome in light path
One click to right
Apotome out of light path
- If you want to use the computer, turn on or wake up computer
- Log in to Zeiss account
- Run Zen
- Best way to load settings:
Open an image from an earlier session that worked well.
Click on Acquisition tab; this will not work in Locate menu.
Click "Reuse" button to load settings.
People keep saving over the settings in the Experiment Manager pull down menu so settings loaded from the menu are likely to be incorrect.
- If you are looking by brightfield, DIC, Nomarski, crossed-polarization, or phase contrast, you must set up Köhler illumination.
See this webpage http://microscopynotes.com/koehler/ and follow step by step:
For simple snapshots, you may want to set up autosave to save in both Zeiss native format and export as TIF.
- Put your sample on the microscope
- Using the touch pad turn on TL or use the computer "Locate" tab and click on Brightfield, DIC, or Phase.
- Adjust light on front bottom of microscope
- Open iris diaphragm
- Focus on sample
- Close field diaphagm
- Using knobs next to condenser to move it up and down, focus light to a small bright spot
- Using small metal knobs on front of condenser, center small bright spot.
- Open field diaphragm slowly to edge of field of view. Do not open all the way!
Do not save as jpeg!
Make sure you update the file name each time you switch to a different sample!

About the microscope
If you save your files in the .czi format, there is a wealth of metadata available for quantification. These files can be opened in ImageJ when the LOCI plugins are installed. However, if (for whatever reason) files are saved as tif, here is an example of measuring areas when images are taken with a 10X lens and no binning.
If you save your files as jpg, why bother imaging with a top-of-the-line microscope? Let's take high resolution pictures and then save them with lossy compression.
