1. Introduction
The SPECTRA III (L) light engine consists of up to 8 individually addressable solid-state light sources with
integrated electronic control systems. The constituent light sources may be LEDs, luminescent light pipes or
lasers. The outputs of the constituent 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 or a liquid light guide (LLG). An onboard
photodiode 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 SPECTRA III (L) light engine® are controlled by an on-board microprocessor operating Lumencor
firmware accessed via one of two serial interfaces, USB/RS-232 or TCP. The user can enable or disable
each source independently by serial commands as well as change the intensity of each source
independently. The SPECTRA III (L) light engine can either be controlled by third-party image acquisition
software or by a GUI resident on the on-board 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. The only manual
control is the master power switch on the front panel. 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
the rear.

SPECIMEN
The model name, unique 4- or 5- digit serial number and certification markings of the light engine are carried
on a label affixed to the rear panel. Performance specifications for individual light engines are listed on the
certificate of conformance included with the shipping documents e-mailed to the customer (Figure 1).
3.2 Installation!
When setting the SPECTRA III (L) light engine up for use, place the unit on a hard surface and avoid blocking
or restricting airflow at the air inlets (front panel; Figure 3) or exhaust ports (rear panel) on the enclosure.
Restricting the airflow will cause the unit to operate at elevated temperatures and will result in decreased
product life and/or premature failure. The SPECTRA III (L) light engine must be operated in a noncondensing environment (dew point <10ºC with controlled ambient temperature <30º C). Thermal overload
protection is provided by the onboard microprocessor in conjunction with an onboard temperature sensor. If
the internal temperature registered by the sensor exceeds 50°C OR the fan rotor is stopped, all light output
channels automatically turn OFF and are locked in this state until the internal temperature is below 50°C and/
or the fan restarts. The current reading of the onboard temperature sensor is displayed on the front panel
status display (Figure 3) and in the Control GUI
(Section 3.3.3).
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 light output 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 light output.

status indicator display; Figure 3) provides a warning indication that one or more light sources are active and
emitting invisible and/or visible radiation.
The Remote Interlock Connector: (rear panel, lower left) is provided to allow for connection of a remote
interlock. When this interlock is open it will shut off light output. After the interlock has been opened, the
Manual Interlock Reset button will need to be pushed to resume light output.
Note: In the event of ANY normal or abnormal interlock fault condition (including high ESD/EMP/EFT
conditions ~2kV) you MUST clear the latch fault condition by depressing the manual reset button.
3.3.2 Start Up!
1. Insert the light guide and secure it with the set screw [1,2].
2. Insert the external gate jumper (Figure 2) in the labeled socket on the front panel (Figure 3). Insert the
remote interlock jumper in the labeled socket in the lower left corner of the rear panel.
3. Insert the control key, turn it to the ON position.
4. Connect the isolated DC power supply to the light engine.
5. Connect the AC power cord to the DC power supply.
6. As soon the DC power supply is energized, the master power button (top right) will automatically light up."
The light engine automatically starts when the power is connected; there is no need to push the master
power button [3].
7. Wait 30–45 seconds for the initiation sequence (onboard microprocessor boot-up) to complete." Do not
press any buttons or insert any plugs during this time.
8. When the initiation sequence completes, “LUMENCOR” will flash on front display panel and then be
replaced by a display showing the current light engine IP address, the internal temperature and the fan
status." At the same time, the fan will come on at HI for about 2 seconds and then shut off automatically.
9. The light engine is now ready for use.
Notes
[1] Ensure that the distal end of the light guide or optical fiber is safely 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] The 3 mm liquid light guide output coupler incorporates an electrical power interlock switch in the back of
the receptacle. The liquid light guide must be fully inserted in the receptacle to activate the interlock.
Electrical power supply to the light engine cannot be turned on via front panel power switch until the interlock
is activated.
[3] 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).

3.3.4 Control via Serial Ports!
SPECTRA III (L) 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 individual color channels. Only one of the two 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 SPECTRA III (L) 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 SPECTRA III (L) 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 SPECTRA III (L) 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 “SPECTRA III (L)” by turning the pod control knob. Press the MODE button
again to select SPECTRA III (L) 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

conveniently addressed using an accessory BNC breakout cable
(Lumencor part no. 29-10156 or 29-10216; Figure 6) connected 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!
SPECTRA III (L) light engines may incorporate different types of
solid state light sources. Constituent light sources may include
LEDs, luminescent light pipes or lasers. The light sources installed
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 liquid light guide (LLG) or
optical fiber (Figure 1). Laser sources are listed on a label affixed to
the light engine (see page 7) together with their center wavelength
and maximum output power. 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 userexchangeable and changes require return of the light engine to Lumencor’s factory for service (see Section
7). Since changing bandpass filters will result in source output power changes, a new certificate of
conformance will be provided as part of this service.

Unusually weak fluorescence
signals across all detection
channels
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).

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) liquid light
guides, 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.
