Basic Operation
Imaging basics
Iris diaphragm
Move the diaphragm slider to adjust the amount of transmitted light to reach the sample.
Opening or closing the iris diaphragm regulates the resolution and contrast of an image.
For transmitted light imaging, slide the diaphragm slider to the left.
This opens the diaphragm to allow in the maximum amount of light and increase resolution.
For optimal fluorescence imaging, slide the diaphragm slider to the right.
This closes the diaphragm to allow in the minimum amount of light and increase contrast.
For automated cell counting, slide the diaphragm slider to the Δ mark (2 cm from the right).
This allows the optimal amount of light for dye exclusion based cell counting.
Phase annuli
The phase annuli slider can be adjusted for brightfield or phase contrast imaging with the three
annuli for transmitted light imaging.
For brightfield imaging, move the phase annuli slider to BF.
For phase contrast imaging at 4X, move the phase annuli slider to Ph1 4x.
For phase contrast imaging at 10X, 20X, or 40X, move the phase annuli slider to Ph2
10x/20x/40x.

Imaging control panel
FILTER CUBES panel: The filter cubes panel shows the three
interchangeable filter cubes for fluorescence imaging and one white
filter cube for transmitted light imaging. The selected filter cube is
highlighted in blue. Each filter cube can be renamed and its
pseudocolor selected in the Settings.
To select a filter cube, move the filter cube selection tail in or out.
OBJECTIVES panel: The objectives panel shows the selected objective
and its adjacent objectives. The selected objective is highlighted in
blue. The position, magnification, numerical aperature, manufacturer
and a description of each objective may be modified in the Settings.
To select an objective, turn the objective turret wheel.
Due to the significant differences in objective lengths, take care when
turning the objective turret:
1. Lower the turret by using a preset focus position, the coarse
focus slider, or the coarse focus knob.
Caution! Lower the objective turret sufficiently or the
objectives will hit the insert plate and may be damaged.
2. Turn the turret to the desired objective.
3. Raise the turret using a preset focus position, the coarse focus
slider, or coarse focus knob.
Parfocality correction compensates for deviations along the focal
plane between different objectives. This feature helps maintain focus
when switching to a different objective. The CELENA®S is
precablitrated for the objectives installed at the time of order.
To turn parfocality correction on or off, click Parfocality correction.
Calibrate all objectives when you add or change objectives.
To calibrate:
1. Click LIVE.
2. Turn off Parfocality correction.
3. Place a slide onto the stage.
4. Select an objective.
5. Focus as sharply as possible on the sample and click SET.
6. Repeat with the next objectives.
Important! Parfocality correction can only be used with objectives corrected for the
same vessel bottom thickness (i.e. long working distance objectives cannot be
calibrated with coverslip-corrected objectives).
LIGHT panel: Use the light panel to control the intensity (%), gain (db), and exposure (ms) of the
selected filter cube. The current pixel depth is displayed in the panel and may be changed in the
Settings.
To turn the light source on or off, click the ON/OFF switch.
Light (%) is the intensity of the LED. Gain is the camera’s amplification of the signal. The gain is
analog up to 18 dB, meaning that signal will increase independently of the noise. Values above
18 dB are digital, meaning that both signal and noise will increase. Exposure is the amount of
time that the camera shutter is open to allow light into the sensor.
To adjust values, drag the bars, click the arrowheads, or turn the mouse wheel while hovering
over the sliders.
To colorize images, click Pseudocolor. Pseudocolor can be applied before or after capturing the
image.

8
FOCUS panel:Use the focus panel to focus and to preset focus positions. The preset focusing
speed and distance moved can be adjusted in the Settings.
To focus, manually manipulate the focus knobs or use the sliders in the focus control panel. Drag
the bars, click the arrowheads, or turn the mouse wheel while hovering over the sliders.
Click Fine AF to finely tune focus. The Fine AF Z-scan range can be adjusted in the Settings.
The focus memory feature allows the user to preset focus positions:
1. Move the focal plane to the desired position (move the objective turret) and click the SET
button. The SET button is highlighted in blue when selected.
2. Select the number that you want the position stored on. A keyboard will appear on the
screen. Label the position as desired (e.g. 10X e coli).
Important! Do not touch the focus knobs during the process.
3. Repeat the process for the various positions you want stored. Numbers with stored
positions will be highlighted in blue.

1 second without focus drift correction or 1 minute
with focus drift correction. Up to 10,000 images can
be captured per sequence. Up to 3,000 images can
be captured when the interval is set to continuous
and the number of images captured is directly
affected by exposure time.
Important! Exposure time cannot exceed
interval time. Make sure the interval exceeds exposure time.
4. Select whether to correct for focus drift during time lapse imaging. Focus drift is a normal
phenomenon in live cell imaging. You can select how often to correct the focus (correction
frequency) and how many images above and below the current focal plane to scan to find
the optimal focus (Z-scan range) depending on the expected focal drift between images and
the objective used.

The scan interval distance between images is 50% of the depth of focus of the objective used
and directly affects the Z-scan range. For example, if you expect the focus to drift 30 µm
between images and you are using TC PlanFluor 20X objective, you know that the Z-scan
range of that objective for +/- 5 images is 21.40 µm, which would be inefficient to correct
the drift. You would need to set the Z-scan range to be +/- 10 images (40.85 µm) to account
for the expected drift.
5. Designate the file path for captured images and enter the desired file prefix. A file name
extension will be automatically added as images are captured and saved.
6. Click RUN.
Important! If using the onstage incubation system, place the sample in the system

Dilution Factor: The dilution factor is used to calculate cell concentrations. Assuming a 1:1
ratio of stain to cell suspension, the DEFAULT dilution factor is preset to 2. Adjust this value
according to the dilution of the cell sample.
Live Cell Sensitivity: Live cells with intact cell membranes exclude dyes like trypan blue and
Erythrosin B. The dyes form halos around live cells and stain the cytoplasm of dead cells or
cells with compromised membranes. With a higher live cell sensitivity, the instrument can
detect smaller cells by registering smaller halos.
Roundness: Cells are not all completely spherical. Adjusting the roundness to detect cells of
various shapes. Higher values lead to the counting of rounder cells and excludes objects with
less roundness. Lower values are suitable for counting cells with irregular shapes.
