1. Introduction!
The CELESTA light engine consists of individually addressable solid-state laser light sources with integrated
electronic control systems. The outputs of the laser light sources are refined by bandpass filters and
merged into a common optical train directed to the light output port on the front panel. The light output port
has a built-in adapter for connection to an SMA-terminated optical fiber. An onboard photodiode array
continuously monitors the light output and generates a reference signal that is applied to the constituent
sources in a feedback loop to maintain constant light output over time. The light sources within the
CELESTA light engine are controlled by software; via one of two serial interfaces, USB/RS-232 or TCP, to an
onboard microprocessor operating Lumencor firmware. The user can enable or disable each source
independently by serial commands as well as change the intensity of each source independently. The
CELESTA light engine can be controlled by third party microscopy data acquisition software or by a GUI
resident on the onboard microprocessor. Alternatively, the light sources may be turned on and off by TTL
inputs from a trigger device such as a camera or a real-time controller. Optimal internal operating
temperature is maintained by negative pressure air cooling with the air intake at the front of the light engine
and the exhaust fan at the rear.

restarts. The current reading of the on-board temperature sensor is displayed on the front panel status
display (Figure 3) and in the GUI (Figure 5).
3.3 Operation!
3.3.1 Controls and Interlocks!
The Master Power Switch button on the front panel
(Figure 3) turns the electrical power to the unit on or off.
A green power indicator embedded in the button is lit
when the power supply is connected to the light engine
and the power button is in the on position. Initialization
of the onboard computer takes about 30 seconds after
the master power switch is turned on. When
initialization is complete, the status indicator display
(Figure 3) will activate.
The Key Control (Figure 3) must be in the on position
before the lasers can be turned on. The key must be
removed and stored in a secure location when the
product is not in use. ONLY trained individuals should
use and have access to the key. The Master Power
Switch button, Key control and Remote interlock
can be used to shut off laser output.
The Source Enabled indicator LED (below the status indicator display; Figure 3) provides a warning
indication that one or more laser sources are active and emitting invisible and/or visible radiation.
The Remote Interlock Connector (Figure 2): is provided to allow for connection of a remote interlock.
When this interlock is open it will shut off laser output. After the interlock has been opened, the Manual
Interlock Reset button will need to be pushed to resume laser output.
WARNING: Prior to turning the light output on, be sure the output end of the optical fiber is safely directed
into an enclosed optical path (e.g. a beam dump).
Note: In the event of ANY normal or abnormal interlock fault condition (including high ESD/EMP/EFT
conditions ~2kV) you MUST clear the latched fault condition by depressing the manual reset button.
3.3.2 Start Up!
1. Insert the optical fiber in the light output port (front , right-hand side) and lock it in place using the integral
threaded sleeve.[1].

directed into an enclosed optical path (e.g. microscope
epilluminator or a beam dump) before turning the light
output on. If the light engine is equipped with an output
adapter for an SMA-terminated optical fiber, connect the
fiber to the output adapter using the integral threaded
sleeve.
[2] For subsequent start ups, use the master power button
to start or shut down the light engine. Shut down can also
be accomplished using the “Shut Down” button in the Control
GUI (Figure 4).
3.3.3 Ethernet Connection and Control GUI!
The Web GUI provides a quick and easy way to control the light engine, providing the ability to turn each
source on/off, adjust the power of each source independently from off to full power (Figure 4). The GUI also
tracks the total on time for each laser light source and display output power readings from the onboard
photodiode array. A channel map stored on the onboard computer is used to the define the association of
control addresses with light sources. The channel map can be viewed by sending the command GET
CHMAP to the LAN port. To access the Web GUI on a Windows workstation, follow the protocol below:
1. Go to Start menu > Control Panel > Network & Internet and/ or Network & Sharing Center

3.3.4 Control via Serial Ports!
CELESTA light engines have two serial ports, labeled USB and RS-232 (Figure 3), which can be set to
receive either LEGACY or STANDARD mode commands. Connection to the computer requires a USB-A-to-
USB B cable (29-10058) or USB-to-RS-232 cable (29-10011). LEGACY commands are limited to controlling
on/off switching and intensity adjustment of selected individual color channels. Only one of the two serial
ports can be set to LEGACY mode at one time. The STANDARD mode command set gives access to an
extensive panel of operating status reports and configuration settings in addition to the the basic control
functions of the LEGACY command set. A complete listing of STANDARD mode commands is provided in
Lumencor Light Engine Command Reference (Document number 57-10018). Note that LEGACY and
STANDARD mode communications use different serial protocols (9600,8,N,1 and 115200,8,N,1
respectively). Changes to the command mode setting for a serial port can be made via the Settings screen
of Web GUI (Figure 5). Changes are applied instantaneously and are retained between power cycles.
Select the command mode setting for the serial port that is compatible with the light engine device driver in
the control software. This selection is typically found under the “Devices” tab. The COM port address
assigned by the computer to the light engine USB serial port must be correctly registered in control software
at the same place.
3.3.5 Control From Light Engine Control Pod!
1. Connect the CELESTA to pod (p/n 83-10007) using USB A-to-USB B cable (p/n 29-10058)
2. Open the Web GUI control interface as described in Section 3.3.3.
3. Go to the SETTINGS page in the Web GUI. Make sure that the USB port configuration is set to LEGACY
mode and USB 5V is set to ENABLED.
4. The pod must be set in CELESTA control mode. The light engine control mode setting is shown in green
letters at the bottom of the pod display screen. If the pod is not in CELESTA control mode, change the
setting by holding down the MODE button on the pod until the light engine selection menu appears. Move
the cursor to “CELESTA” by turning the pod control knob. Press the MODE button again to select CELESTA
control mode and return to the main control screen.
5. Follow the instructions on Lumencor’s Light Engine Control Pod Operation sheet (p/n 54-10036). In brief,
press the COLOR button to select output light output channel, press the MODE button to toggle light output
on and off and turn the control knob to adjust intensity for the current light output channel selection.
3.3.6 TTL Control!
The TTL Interface provides users with a faster method of switching
color channel outputs on and off. Individual TTL inputs are
provided for each color channel, as shown in the adjacent table.
As a safeguard against unintended light output when the inputs
are initially connected, the light engine TTL port is disabled and
must be enabled by a serial command. To enable the TTL input,
click the Enabled button next to “TTL inputs” in the GUI under the
Settings tab (Figure 5) or send the standard mode command SET
TTLENABLE to the LAN port. Input TTL signals can be
conveniently addressed using an accessory BNC breakout cable

to the front panel TTL port. The breakout cable also provides a
global shutter input (labeled “shutter”). TTL signals input to the
global shutter will synchronously toggle all currently enabled
source channels on and off.
4. Light Output Characteristics!
The solid state laser sources installed in the CELESTA light engine
and the bandpass filters associated with each are shown on the
Certificate of Conformance included with the shipping documents
e-mailed by Lumencor to the customer. The certificate of
conformance also shows full (100%) power outputs for each
source measured at the terminus of the optical fiber (Figure 1).
Not all sources may be turned on simultaneously. To prevent
exceeding the capacity of the DC power supply, power
consumption is tracked by the onboard computer. If a set limit
(see Governor, Figure 5) is exceeded, either by increasing
intensity settings for sources that are already on, or by turning on
additional sources, commands will be rejected. To clear the error condition, reduce intensities of sources
that are on or turn off additional sources.
Light source outputs are refined by bandpass filters. The specifications of these bandpass filters are
recorded on the certificate of conformance as CWL/FWHM where CWL =center wavelength and FWHM =
full width at half-maximum transmission, both measure in nanometers (nm). Bandpass filters are not user-
exchangeable and changes require return of the light engine to Lumencor’s factory for service (see Section
7). A new certificate of conformance will be provided as part of this service.

Weak fluorescence in all detection channels (DAPI, FITC, TRITC,
Cy5 etc) is likely to be due to poor light transmission by the liquid
light guide, the collimating adaptor or another distal component
of the microscope optical path and not to abnormally low light
output from the light engine.
Unusually weak fluorescence
signals in a single detection
channel (e.g. DAPI)
1. Check that the light engine power output reading in the Web
GUI (Figure 4) is normal.!
2. Check that the dichroic beamsplitter and emission bandpass
filter in the microscope are compatible with light engine
excitation filter specifications shown on the certificate of
conformance (Figure 1).
High, spatially uniform
fluorescence background
Check that the dichroic beamsplitter and emission bandpass filter
in the microscope are compatible with light engine excitation filter
specifications shown on the certificate of conformance (Figure 1).
¶ Open interlocks for these conditions will be indicated by a red status indicator in the lower right
corner of the GUI control screen (Figure 4)

8. Warranty
The CELESTA light engine is backed by a 18 month warranty to end users. Warranty coverage starts on the
original date of shipment from Lumencor. Light Engines qualifying for warranty service must be verifiably
delivering performance that is substantially at variance with the levels documented in the certificate of
conformance. The light engine must also have been used and maintained under operating conditions
consistent with the specifications given in Section 5, and observing all the Precautions and Warnings notified
in Section 2. This warranty does not extend to light engines that have been subject to misuse, accident,
tampering or improper installation. Accessories including (but not limited to) optical fibers, collimators, cables
and control consoles are not covered by the warranties attached to light engines. Please fill out and submit
the online warranty registration form. This will facilitate provision of warranty service should it be required.
