1. Description
The BeST-SLED® Integrated Spectral Bench (ISB2) product is a compact
Superluminescent Diode (SLED) solution employing Luxmux’s high performance Optical
Spectral Engine (OSE2) module. The ISB2 series consists of various multiple SLED
configurations; refer to “Section 12. Ordering Code.” The ISB2 design is based on
Luxmux’s proprietary driver and electronics platform, and consists of the BeST-SLED®
OSE2, independent SLED control, independent monitor diodes on each SLED, thermal
management, communication, user interface software and optional power meter.
Features
-Between two and six superluminescent diodes available (SLEDs) in a single unit
-Each SLED comes with a built-in independent monitor photodiode and one
common thermoelectric cooler (TEC) for all SLEDs
-Fiber-coupled output power from 12mW to 40mW; Free Space output power from
35mW to 130mW
-Bandwidth FWHM from 100nm to 460nm
-Spectral coverage from 1265nm to 1725nm
-Luxmux’s patented technology for spectral stitching provides optimum power and
bandwidth
-Multiple communication interfaces: USB, RS-232, Ethernet
-Internally optimized for maximum coupling efficiency with PM1550-XP Fiber or
PM1300-XP
-Monolithic integration of a Broadband Dual Stage PMF Isolator (35dB)
-Light output: FC/APC Connector (Optional FC/PC or SMA); Free Space light output:
AR Coated Sapphire Window
-User friendly GUI and custom API available for test automation

2. Safety
All statements regarding safety of operation and technical data in this user manual will
only apply when the unit is operated correctly.
The driver must not be operated in environments susceptible to explosion
hazards.
Do not obstruct the air ventilation slots.
If any parts of the driver, or electronics are broken or exposed, contact Luxmux
technical support and do not attempt to operate the unit.
The ISB2 is a Class 1M laser product. It is safe for all conditions of use except when
passed through magnifying optics such as microscopes and telescopes. It
produces a beam that is divergent. If light is re-focused use protective eye wear.

3. Operation
3.1 Parts List
Inspect the shipping container for damage. If the shipping container seems to be
damaged, keep it until you have inspected the contents and the unit mechanically and
electrically.
Verify that you have received the following items within the package:
1 BeST-SLED® Integrated Spectral Bench
1 Power supply. Input: AC 100-240V Output: 12V
1 Power Cord
1 USB 2.0 A to B Cable
1 User Manual
1 BeST-SLED® ISB2 Final Inspection Test Report

3.2 Physical Driver Functionality
Side Panel - Power:
The power side panel consists of the 12V power jack and a two-position power switch
to turn the unit ON/OFF as shown Figure 1.
Figure 1: Power Side Panel
When the unit is plugged in for power and the power button is in the “I” (ON) position
the power LED of the front panel will light up.
The ISB2 can be powered up with the power supply provided by Luxmux or with User’s
power supply if it fits the following specifications:
1. 12VDC (max. 14VDC) and minimum 3A current supply capability.
2. Power Barrel Connector Jack 2.00mm ID, 5.50mm OD, 9.5 mm Length.
3. Center Positive

Side Panel –Communications and Control:
The right-side panel consists of a USB Type B connector, Ethernet and RS232 for
communication and a 7-position slide type switch module; see Figure 2.
The left-most switch controls whether the driver will be operated in MANUAL MODE or
PC MODE.
If the driver is controlled through the PC based software or Luxmux’s API, connect either
a USB, a Serial and/or Ethernet cable for communication. In MANUAL MODE, no
connection to USB, RS232 or Ethernet is required and the SLEDs can be turned ON/OFF
with the 6 switches on this side panel.
The switches are labeled from 1-6 corresponding to the SLED number, with SLED 6
having the shortest wavelength and SLED 1 having the longest wavelength. Please refer
to the Final Inspection Test Report included with the BeST-SLED® Integrated Spectral
Bench for SLED numbering as well as corresponding wavelengths and maximum
operating currents.
When turning individual SLEDs “on” or “off” in MANUAL MODE they will be driven at
their default current settings. Default current settings for MANUAL MODE can be
changed through the software and will be explained in the Software Operation section.
When running the Luxmux software, toggle the left switch to PC MODE in order to
control SLEDs from software. The SLED control will be disabled in the software if
operating in MANUAL MODE. Software will still display current levels when running in
MANUAL MODE but users will not be able to adjust the operating currents.

Front Panel - Light Output:
The front panel includes three LEDs, vent holes and light output connector, allowing
users to connect their own fiber optic cable to the ISB2; see Figure 3. BeST-SLED® comes
with FC/APC as standard, but FC/PC and SMA connectors are available upon customer
request.
When the unit is plugged in for power and the power button (side panel) is in the “I”
position the red “POWER” LED will light up.
The yellow “READY” LED will start blinking until the unit is ready for operation. When
the yellow “READY” LED stops blinking and stays on, the SLEDs are enabled and users
can turn them on. When SLEDs are turned on and light is being emitted the green “ON”
LED will light up.
If the ISB2 is controlled through the Luxmux software, the SLED controls will be disabled
until the unit is ready, as explained in the Software Operation section.
Otherwise, in MANUAL MODE or Luxmux’s API, if the user turns on the SLEDs before the
unit is ready, the unit will not emit light until the “READY” stops blinking. Once the yellow
“READY” is on the ISB2 will allow for SLEDs to start emitting light.
In the event of a fast and large temperature change in the environment, the unit may
stop emitting light until the BeST-SLED® is ready again, in such case, the yellow “READY”
LED will start blinking.

Back Panel - Thermal Management:
Free air circulation around the rear of the unit should be maintained for good thermal
performance. If the ISB2 is operated in environments over 35 Degrees Celsius the ISB2
should be mounted to an external heatsink. Free air circulation around the ISB2 is
required when it is used without a heatsink. A minimum of 0.5”clearance is
recommended for free air circulation around the top and sides of the ISB2 Unit.
Air circulation is located on the back panel of the ISB2 Light Source, while additional
ventilation holes are located in the front panel. Ensure vents are not obstructed to allow
for maximum air flow.
The back panel includes two fans as shown in Figure 4. Upon powering up the unit, each
fan is regulated automatically to its maximum speed. Users do have the option,
however, to control fan speed manually as explained in the Software Operation section.
If the fan is not working and the heat sink temperature goes over 60˚C, turn the unit off
and contact Luxmux technical support.
