Leica dissection microscope with fluorescence

To sign up for microscope in advance, use Histopath Core reservations webpage on Labvantage LIMS. Leica M165 Fluorescent Stereo (dissecting) Scope

This microscope has grayscale brightfield and GFP and RFP flourescence.

If you want the details in 150 pages, Leica's PDF manual.


How to Turn On (follow step-by-step):

  1. Sign in the paper logbook. Really, this is step 1.
  2. Switch on base of microscope on right.
  3. Switch on rear of pillar. (Maybe switch these to a single power strip switch?)
    Before give the microscope a minute or so to initialize.
  4. If using fluorescence, switch on front of power supply up on shelf.
  5. If taking pictures, log in to computer. Password is taped to the screen.
  6. Run Leica software.
  7. Initializing mesages...
  8. Operate from touchscreen tabletop pad or from computer software.


Methods for automatically taking multichannel images can be strung together.

The best way to save files is to group them within an experiment in Leica format. Each sample would be saved as a different experiment. This means you can take multiple pictures of each sample and only have to enter a file name once.

Images are easy to open in ImageJ and we have macros we can tweak to apply colors and automatically make figures in any format required. For instance, we can have ImageJ open every image in a directory and make montages of green, red, brightfield, and merged with a scalebar and saved with the correct filename. Automation saves a lot of time. Ask the Microscopy Core staff for help with this.

This microscope does not have a stage ideal for tiling, but tiling can be done.


If software crashes, data may be recoverable if you don't run the software first. The raw data may be in a Leica directory where they can be copied out before restarting the software.




Section to be written: fluorescence microscopy settings and how to take pictures in linear range for quantification.

Notes from day training with Leica:

Two switches
1. Base
2. Switch on column - let initialize - wait for 2 LCD panels

knobs on side of base change baffles and angles, clicks to be reproducible

explain intensity max - change intensity otherwise

Starting software:
- default dynamic widefield tree
- dynamic

camera needs to be stopped to adjust microscope
