Basics

Normal operation of the StedyCon microscope through a normal confocal scan with the Pollen slide.  Additional books will cover other types of scans, e.g., Z-Stacks, Tiled scans, STED.

These documents are to reinforce, not replace, hands on training on the microscope.  All users MUST recieve training from Cell Imaging Staff prior to use of the instrument.

Stop: This is a first draft in progress. The information is not/may not be accurate.

The Microscope

Your first task will be to get your sample in focus and in the correct position.  This is done with the microscope and through the controls on the microscope itself.

  1. Apply a drop of oil to the lens if needed (60X, 100X).  (The lenses are parafocal,parfocal, so you can start at lower magnifications first.)first and work up to the 60X, 100X.
  2. Place your slide with the coverslip down.  Tilt the transmitted light arm back using the white housing at the top.
  3. Use the X-Y controlledcontroller to get close to position.position (below).
  4. Set up the appropriate light path (below).
  5. Use the microscope to adjust focus and position (below).

Bright-field controls

  1. Verify that the lamp is on by putting your hand in the air path between the lamp and the condenser.  If it is not, it may be switched off on the left panel or the intensity set to off.
  2. Verify that the condenser turret is not blocking the beam.
  3. Bring the Transmitted Light arm forward.
  4. Set the light path (on front panel) set to Eye
  5. CondenserUse dialthe EPI Shutter button on the right panel to set to not block the upper beam.
  6. Transmitted Light arm should be forward.

    Eyes and channel

    1. Block the bright-field light with the condenser turret.  This is a beam block.
    2. Just to the left of the lamp, there are a number of filters.  These do get moved to the wrong spots.  Left to right, they are:
      1. Iris: Should be pulled out.
      2. A.S. Two knobs
      3. ND4: Neutral Density Filter: should be pulled out for maximum intensity
      4. ND8: Neutral Density Filter: should be pulled out for maximum intensity
      5. Filter: Should be pushed in.  If out, it will block the path.  Can be used as a beam block.
    3. Lever on the right side of the filter turret must be back.  This is a beam block.
    4. EPI Shutter: set to one of the epifluorescent channels: 
      1. DAPI

    Data Acquisition

     StedyCon Welcome screen

     

    Acquisition

    On the welcomeStedyCon Welcome screen, press Start Up.  The process will take a few minutes.  Wait for the status to change from Starting Up... to Ready for Imaging.

    Click on Startup.  The start process will take a few minutes.  The laser box Standby/Ready light will turn green.  Eventually, the status will be Ready for Imaging.

    Status and Interlocks

    Interlocks tab with 5 green and 2 red

    Click on the Status Info button and a Status window will pop up in a new tab.

    Double click on the Interlock line in the STEDYCON State section.  This will pop up a new tab with the Interlocks status.

    There are 7 interlocks.  The first 5 shouldmust be Green before starting a scan.

    1. Key: Is the key on the laser box on?
    2. Head:
    3. Interlock 1:
    4. TL arm & Condenser:  There are two interlocks:
      1. TL arm: is the transmitted light arm (tower) forward?
      2. Condenser: is the dial set so that the brightfield path is blocked
    5. Beam path: On the front of the microscope, switch the path to L100
    6. Software: will still be red.
    7. Combined: will still be red.

    The fluorescence source is not part of the interlocks.  You still need to block its path to get a good image.  
    - Use the lever under the filter wheel to block the fluorscencefluorescence source.  
    - Set the fluorescence filter to ----.
