Confocal Principle
Signals from above
and below the plane
of focus fall outside
the pinhole and are
blocked
Carl Zeiss - Training Application and Support Center
Only signals from
plane of focus pass
the pinhole and are
detected - producing
a “optical section”

Adjusting the scan speed
Adjust the scan speed - a
higher speed with averaging
results in the best signal to
noise ratio. Scan speed 8
usually produces good results.
Use 6 or 7 for superior images.

Choosing the Dynamic Range (8/12 Bit per pixel)
Select the dynamic range - 8
bit will give 256 gray levels,
12 Bit will give 4096 levels.
Photoshop 5 will import 12

Channel Settings - Adjusting the Pinhole
Pinhole size
= 1 Airy unit
Set pinhole size to 1 Airy unit for best compromise between depth discrimination and efficiency.
Pinhole adjustment changes the “Optical slice”.
When collecting multi channel images, adjust the pinholes so that each channel has the same
“Optical Slice”.
This is important for colocalization studies.

Adjusting the Laser, Gain and Offset using a Multi Track Configuration
Each channel is selected independently by
clicking on the colour button indicating the
channel i.e. Ch2-T1 (Channel 2, Track 1).
The laser power and all other parameters
are optimised as described in the previous
slides for each selected channel.
For accurate colocalisation, adjust
each Pinhole so that each channel
has the same Optical Slice
To adjust laser, gain or offset for a single track in a multi-track
configuration it is possible to temporarily deactivate the other
tracks in the Configuration control

window and adjust the Laser intensity, Detector Gain, and Amplifier Offset
as described previously.

Line Averaging
Averaging improves the image by
increasing the signal : noise ratio
Averaging can be achieved line by line,
or frame by frame
1) Select Line or Frame under Mode in
Scan Average within the Mode panel of
the Scan Control window
2) Select Number for averaging. The
more the better for the signal to noise
ratio (max 16) in this case, each line will
be scanned 4 times. But: Averaging
increases the exposure time of the
sample!!

Zeiss LSM 510 META - Guided Tour
Frame Averaging
1) Select Frame
2) Select the Number for averaging - The more the
better for signal to noise ratio (max 16).
Continuous averaging is possible in this mode.
Frame averaging helps reduce
photobleaching, but does not give quite
such a smooth image. There is also a
longer delay between each track when
using “Multi Track”.
Continuous averaging has a Finish button
which allows the scan currently in progress to
be completed before stopping

Using Auto Z Brightness Correction
Auto Z provides an automatic gradual adjustment of Detector
Gain, Amplifier Offset, Amplifier Gain, and Laser intensity
setting between the first and last optical slice of a Z Stack.
1) After defining the Z position of the first and last optical slice
activate Auto Z.
2) Move to the First Slice and adjust the parameter for the
image acquisition in the Channels panel for each used
channel as described in the previous slides. Then click on
Set A to store the values.
3) Repeat the procedure after moving to the Last Slice. Click
on Set B to store the parameters for the last slice.
Note: Positions A and B do not have to be the first and last
slice of a stack and can also be defined simply by focussing
to the appropriate positions, adjusting the parameters and
pressing Set A or Set B.
4) The parameters for image acquisition will be gradually and
linearly adjusted between the first and last slice of the Z
Stack. Thus signal intensity and image quality is comparable
throughout the Z Stack.
