recommended to reclassify the final optical system in order to determine its total degree of optical radiation hazard. The reason for this is that the Class may increase under these conditions. It is the responsibility of a person (or organization) who performs such integration to provide correct reclassification for the optical system at the final stage. It must be noted that it is the user who is responsible for being aware of possible risk associated with using Class 1 laser products as well as being adequately trained for working with such light sources. Superlum is not liable for any personal injury, property damage, or other (direct or indirect) damage of any nature caused by personal faults, improper and/or inadequate using of the instrument coming from disregarding the necessary aspects of laser safety.
According to IEC 60825-1, this product has been classified for an exposure duration of up to 100 ms. For other practical applications in which the exposure duration is greater than 100 ms, the product must be reclassified.
CLASS 3R Laser Product
Light sources assigned to Class 3R emit optical radiation that can exceed the MPE (Maximum Permissible Exposure) under
NOTE
BroadLighter-M Series User Manual Revision 16
13
the direct intrabeam viewing, but in most cases the risk of injury is relatively small because the AEL (Accessible Emission Limit) for Class 3R is only 5 times greater than the AEL for Class 1, which is safe for the user. The risk of injury rises as the exposure duration increases. The exposure will be safe for the user unless it is a deliberate ocular exposure. The risk of injury is actually minimized due to the following facts:
Unintentional exposures would rarely reflect worst-
case conditions, for example, of beam alignment with the pupil or worst-case accommodation.
The inherent safety margin in the MPE.
Natural aversion behavior for exposure to bright light
for the case of visible radiation and by the response to
heating of the cornea for far infrared radiation. The direct intrabeam viewing is supposed to be unlikely for possible practical applications of this instrument. Otherwise, the user should reclassify the instrument. If you are unsure about providing the correct reclassification, contact Superlum on this issue. Using controls, adjustments or operating procedures that are different from those specified in this manual may result in radiation exposure hazardous to the user. When the instrument is used with certain optical elements, such as optical amplifiers, lenses, collimators, etc., which are not supplied with the product as original accessories, or the product is integrated into a high-

1.2 Instrument Description
For a number of optical applications, such as optical coherence tomography, optical metrology, characterization of optical components etc., broadband light sources based on the use of SLD modules are considered to be best suited. The reason for choosing these optical modules is related to their remarkable performance parameters. Among all types of modules presented on the market, the SLD modules best combine high optical power similar to that emitted by laser diodes with broadband optical spectra characteristics of LEDs. These advantages of SLDs allow the user to avoid unwanted interference effects, like speckle or ghost signals. In contrast, narrowband light sources such as laser diodes often give rise to such effects due to a high temporal coherence of their output emission.
The BroadLighter-M is an advanced SLD-based broadband light source intended for a benchtop applications. Among other broadband light sources of this kind, it features excellent performance parameters, easy-to-use front-panel operation, and long-term stability of its technical characteristics, high reliability, minimal maintenance, and many others. The instrument can be controlled either manually by using its front­panel controls or remotely via PC. For remote control, the instrument is equipped with USB and REMOTE CONTROL interface. Superlum BroadLighter-M Companion Software,
1. General Information
26
which is supplied with the instrument, has a user-friendly interface that permits the user to put the instrument under remote control immediately after its installation.
In comparison to a standalone SLD module, the BroadLighter-M demonstrates the extended optical spectrum with an extremely wide -3 dB bandwidth, which in turn corresponds to very low temporal coherence. This occurs due to combination of the optical emissions of up to four spectrally matched SLD modules. The actual number of SLDs depends on your instrument configuration. Figure 1.1 sketches the principle of light combining in the BroadLighter-M. To combine broadband emissions of the SLDs broadband fiber-optic couplers are utilized. The couplers feature low insertion losses and small changes in the coupling ratio for the necessary range of wavelengths.

The internal structure of the BroadLighter-M has a modular design. The instrument consists of an optical unit, driver unit and a main unit. Optical unit has optical components comprising the optical scheme of the instrument. It also stores the information about the SLD operating parameters, the driver unit has an integrated DC power supply, as well as driving electronics and temperature control for SLDs. The main unit acts as a motherboard for optical and driver units. This design principle provides the possibility for a flexible exchange of unit and the ability to adapt and upgrade the instrument to a particular customer application.
1. General Information
28
Superlum SLD modules used in the BroadLighter-M are fiber-coupled optical modules with a built-in thermoelectric cooler (TEC) and a temperature sensor which are both necessary for active temperature control. Superlum current-and temperature controller is used to control the driving current and operating temperature of an SLD module.
The instrument has a wide-range voltage power supply suitable for the 100-240 V AC power lines. All essential information about AC power requirements is shown on the rear panel of the instrument. It is important to note that the BroadLighter-M is intended for indoor use only. For more information on environmental conditions, refer to section "Specifications".
This equipment is intended for fiber-optic applications. To serve this purpose, it is equipped with FC/APC fiber output. Each BroadLighter-M is shipped with an individual optical patchcable which is used to deliver the optical output power of the instrument to the user measuring equipment. It is important to note that the patchcable provided with the instrument is specially selected to best match the optical output of the instrument. With the patchcable attached, a low-loss connection between the BroadLighter-M and the patchcable is obtained. Connecting user-selected patchcables to the BroadLighter-M output is permitted but not recommended,
BroadLighter-M Series User Manual Revision 16
29
because in this case the minimum optical losses in the instrument-to-patchcable connection can hardly be ensured. FC/APC connectors of its ends is the crucial requirement for the patchcable to be used. Contact Superlum first if you would like to use other types of optical connections.
The BroadLighter-M incorporates the following safety
features required by IEC 60825-1:
Key-operated master control — located on the
front panel of the instrument, this switch provides access to activation of the optical output. The BroadLighter-M is inoperable when the key is removed. Using the key-operated master control prevents unauthorized activation of the optical output emission.
Emission indicator — the LED integrated with
SLD emission activation ON/OFF button, lights up green when the optical power is enabled, thereby warning the user about the output emission. The LED will switch to red when the SLD emergency switch-off occurs.
Emission time delay – there is a 3 second time
delay between pressing the emission ON/OFF button and the emission activation.
1. General Information
30
Remote Interlock connector — this feature is
located on the rear panel of the instrument. It allows the instrument to be connected to your local external controls for laser safety. In order to enable the BroadLighter-M, a short circuit must be applied across the terminals of the Remote Interlock connector. The instrument remains inoperable unless the Interlock connection is made. BroadLighter-M is shipped with a shorting device installed in the Interlock connector. If you are not going to use this feature then you can leave the shorting device installed. With this device installed, you will be able to use the instrument independently of your local laser safety system. If you wish to make use of the Interlock feature you will need to acquire the appropriate connector mate and wire it your remote Interlock switch. Next, remove the shorting device by carefully unscrewing it from the socket and install the connector into the Interlock input. The BroadLighter-M interlock input only accepts a 2.5 mm monophonic jack.
Visual and audible warning about optical
output emission — these features start to operate
when the user activates the optical output by
BroadLighter-M Series User Manual Revision 16
31
pressing the ON/OFF button. Remote IF connection can be used to transfer a warning signal from BroadLighter-M to the external warning system.
Optical radiation hazard labeling — the cabinet
of each BroadLighter-M contains a set of warning labels informing the user about the Class of radiation hazard to which the instrument is assigned. Classification is based on the rules specified in standard IEC 60825-1:2014 "Safety of laser products — Part 1: Equipment classification and requirements". Each BroadLighter-M that is assigned to this Class of laser products carries on the instrument's cabinet a set of warning labels with the necessary information according to its laser hazard.
Overshooting protection — BroadLighter-M
contains a safety circuit preventing the signal from overshooting by shutting down the output.
Using controls, adjustments, or operating procedures that are different from those specified in this manual may result in radiation exposure that is hazardous to the
user.
CAUTION
1. General Information
32
Each BroadLighter-M is assigned to a particular Class only if it completely meets the requirements specified in IEC 60825­1:2014 for that Class. According to IEC 60825-1, Class 1, Class 3R and Class 3B products have been classified for an exposure duration of 100 ms, which is estimated to be a worst-case scenario. For other practical applications in which the exposure duration is greater than 100 ms, the product must be reclassified.

3.3 Operating Instructions
To get started with your BroadLighter-M, carry out the following steps in the following order:
1. Perform preparation for use. Consult section "Preparation for Use" for more information if necessary.
2. If you have the external controls for laser safety in your local area, connect the BroadLighter-M to your local external controls for laser safety. Use the REMOTE INTERLOCK jack on the rear panel of the instrument for this connection.
3. Connect the optical patchcable supplied with the BroadLighter-M to the front-panel FC-APC socket. The other end of the patchcable goes to your measuring equipment, e.g. an optical power meter. To obtain low insertion optical losses in the instrument-to-patchcable connection, always keep the connectors clean.
4. Turn the MASTER KEY control clockwise to position "I". Once the key has been turned, the instrument boots and runs an internal test to verify the statuses of the internal components. It also checks whether the remote interlock connection or shortening device installation is made or not. If the test passes, POWER LED glows green and you are able to activate the optical output of the instrument. If the test fails, the instrument POWER LED glows red. In this case turn the MASTER KEY to
BroadLighter-M Series User Manual Revision 16

5.2 Cleaning
This section advises on the cleaning procedures for BroadLighter-M. Optical connectors may require at least two cleanings. The initial cleaning gently removes any grit and oil. If filmy deposits are still present at an optical interface, the second cleaning should be performed. It is not uncommon for a patchcable or connector to require more than one cleaning.
1. Never look into the end of an optical aperture or optical patchcable when the BroadLighter-M is operational.
2. Always disable the optical output of the instrument before cleaning the optical connectors.
WARNING
5. Cleaning Instructions
90
1. To clean optical fiber ends, use natural cotton swabs or specialized fiber-optic cleaning equipment.
2. If you use compressed air for the cleaning, make sure that compressed air is free from dust, water, and oil.
3. Be especially careful when inserting the ferrule of a patchcable into a connector or adapter. Make sure that it does not touch the outside of the mating connector or adapter.
4. Never use a cotton swab to dry the adapter inside, because it may damage internal parts of the optical adapter.
CAUTION
BroadLighter-M Series User Manual Revision 16
91
1. If possible, avoid using denatured alcohol because it usually contains additives. Instead, apply alcohol that is used for medical purposes.
2. Always recap the optical output of the BroadLighter when it is not in use.
3. Apply as little alcohol as needed for cleaning. This allows you to avoid getting any amount of alcohol inside the optical adapter. If, after all, the adapter contains some alcohol after cleaning, use compressed air for drying it.

6. Service and Support
94
3. Pack the instrument in the original shipping container, or use an adequate replacement following the directions below:
• Wrap the instrument in antistatic plastic to reduce the
possibility of damage caused by electrostatic discharge.
• Use a double-walled, corrugated cardboard carton to
pack the instrument.
• The carton must be large enough to allow
approximately 7 cm on all sides of the instrument for packing material, and strong enough to accommodate the weight of the instrument.
• Surround the equipment with packing material to
protect the instrument and prevent it from moving in
the carton. The best solution is to use Air Cap™. Air Cap™ looks like a plastic sheet filled with air bubbles. Use the pink (antistatic) Air Cap™ to reduce static
electricity. Wrapping the instrument several times in this material will protect the instrument and prevent it from moving in the carton.
4. Seal the carton with strong nylon adhesive tape.
5. Mark the carton "FRAGILE, HANDLE WITH CARE".
6. Retain copies of all shipping papers.
BroadLighter-M Series User Manual Revision 16
