REASONS WHY

point
Sample Stage Preparation
If using small cylindrical
sample holders, use the
setup to the right. Notice
the different types of
“sample locks” (which
hold the samples firmly in
place) and “sample sites”
(where the sample is held
on the stage during
imaging).
If using glass slides, use
the setup to the right.
Notice the “oil deposition
site” (where oil is
deposited before using
the 60x Objective) and
the “stage key” (used to
align to microscope when
inserting stage).

Place sample site on the
stage (small cylindrical
samples).
Once sample slide is in
place, secure it using
sample locks.
Place sample site on the
stage (glass slides).
For small cylindrical
sample holders, place the
sample onto the sample
site and lock it in with the
sample locks.
For class slides, place
sample into sample site
so that the area of
interest is located near
the “3” marker on the
stage.
This is good practice
because the machine will
start imaging at this
center point.
Ensure that the cover slip
side of the glass side is
facing down and away
from the Operator.
Once sample slide is in
place, secure it using
sample locks.
Open microscope hood
and insert stage.
Align the stage key hole
with the cylindrical piece
of metal on the
microscope that fits
inside it. Close the hood,
and now the sample is
ready to be imaged.
One aspect is essential;
the Operator must make
sure that the cover slip
has a height equal to or
less that a #1.5 cover slip,
otherwise the sample or
the instrument can be
damaged.

Dye Selection
Select “Set from Dye Data
Base” tab, near the top
left of the yellow
highlighted window
above.
Identify the type of dye of
which the sample is
strained.
Select a dye name on the
list and then click
“Apply”.
If no dye is given, select a
wavelength of light that is
known to excited
fluorophores in that
sample. If that
information is unknown,
then the Operator must
first test the four basic
excitation wavelengths
provided (Blue, Green,
Red and FarRed).
No more than four and at
least two wavelengths
must be selected before
imaging can begin.
The dye name will now
be registered on the
“Selected Dyes” list
(denoted by the green
highlighted window in
the image above).

Click “Start” near the
bottom center of the
screen (denoted by the
red highlighted window
in the image above).
Acquisition of Map Image (refer to “Map Image” tab)
When three or more dyes
have been selected then
the Operator must choose
a combination of two for
the initial image
mapping.
This is done by clicking
on the desired
combination and then
clicking on “OK” at the
bottom of the window.
Select container of
interest.
For glass slides, the
number on the stage of
which the glass slide has
been placed corresponds
to the container number.
Whichever container,
indicated by the light grey
box in the image to the
left, is selected will be the
container that is mapped.
Other parts of the glass
slide can be looked at by
switching containers.
Click “Register” to mark
down all the containers to
be mapped; use the
“Delete” button to remove
registered containers.
Start map acquisition:

Using the window to the
right, adjust the
brightness of the map
image.
Under the “Scanning
Order” section, select to
either image the current
container, containers that
have already been
registered, or manually
select the sections of the
container to be manually
imaged.
If the Operator chooses to
manually select sections,
simply double click on the
acquisition screen inside
one of the large squares
and the machine will
raster that site.
The Operator is now
ready to acquire the map
image. Click “Start”
locate at the bottle left of
the window to the right.
During map acquisition:
Once the Operator has
selected “Start”, the
progress bar can be
observed at the bottom of
the screen, which
indicates the machine is
conducting autofocus and
auto brightness.
At any time, the Operator
can click “Stop”.
Once the progress bar
disappears, the map
image acquisition will
begin. It is at this point
that the Operator can
manually select the boxes
for the machine to raster
if “Manual” was selected.
This can be used if the
Operator finds the
desired feature and
wants to move on, or see
if mistakes have been
made and wants to move
back. “Stop” can be an
excellent time saver,
allowing the Operator to
move forward or
backward in the imaging
process.

Before moving on to
using the Observation
Window, it should be
noted:
Look to the window at
the right indicated by the
green square. In this area
the Operator can select
the cannels that the
image is being displayed
on. By turning these
channels on and off, very
different images and
features can be observed.
When the Operator is
ready to move on, click
“NEXT”.
The image directly above
is the image map created
during the previous
steps. In this window the
Operator can navigate
Try turning off the phase
contrast first. If most of
the image is in phase
contrast, a new sett of
dyes needs to be
selected that will cause
the sample to fluoresce.
DO NOT CLICK “Start” or

start all over.
Observation Window Layout
This is done by double

This changes the area of

At 4X the image is

Use the “Depth” Tab.
Use the “Other

“AF” arrow indicates the
point of autofocus. If the
Operator slides this
arrow up and down, the
depth of focus changes
and the top and bottom of

“End” and “Start” bars are
used to take stacks of
images. Stacks can be
used to generate 3D
images.

for saved images.
“Speed & Quality” is
responsible for image
quality.
Use the “Sensitivity” Tab.
Use the “Laser” Tab.
“Confocal Aperture”
affects the size of the
aperture. Smaller
aperture means less light
is being capture. This is
typically observed at
“x1.0” setting.
This tab is used to change
the sensitivity of the
machine to specific lasers
being emitted onto the
sample.
This tab is used to change
the intensity of specific
lasers being emitted onto
the sample.
Higher resolution means
a much larger file size
and a much longer image
acquisition period.
This is typically seen in
“High Quality”.
A higher sensitivity
means the machine will
detect more photons at
that wavelength. This
feature can be useful
when isolating areas of
interest on the sample.
A higher intensity means
more photons of that
wavelength are being
emitted.
