    Do not use liquid cleaning agents. LASER SAFETY The L4Cc and L6Cc are sources of laser radiations, which present specific dangers. Light produced by a laser source exhibits several proprieties that make it much different from sunlight or from the light emitted from a bulb. These proprieties induce specific hazards associated during operation...
  • Page 9 BIOLOGICAL EFFECTS OF LASER BEAMS Here are some known and documented effects of intense laser light over biological bodies: Ocular trauma: a collimated laser beam, focused by the eye lens, can create an extremely intense light over the retina, even more intense than what would result from a direct viewing of the sun.
  • Page 10 Therefore, Oxxius bears no responsibility in any lack of compliance with safety standards of the environment in which the combiner, OEM version, is used.
  • Page 11 SAFETY FEATURES ON THE LASER UNITS The aforementioned safety standards demand that some safety features are present on the laser units, in order to inform the user about the laser radiation and prevent an accidental exposure. Some of these features are only present on the plug-and-play versions of the combiners LABELLING (ADVISORY LABELS) It is the responsibility of the manufacturer to provide the correct classification of a laser, and to equip the laser with the appropriate warning labels and safety measures as prescribed by the regulations.

  • Page 15: Preface

    2. PREFACE THE OXXIUS LASER COMBINER Oxxius laser combiner is a platform that embeds several sources and combines them in a single output. These laser sources can be either Laserboxx models from Oxxius, or models from third-party suppliers. The L4Cc combiner can house up to four laser sources and two acousto-optic modulators The L6Cc combiner can house up to six laser sources and two acousto-optic modulators The output beam can be available either in free space, or delivered through one or several optical fibers.

  • Page 16: Intended Use

    INTENDED USE The L4Cc and L6Cc combiner are intended for delivering optical signals in industrial, and laboratory environments. Use the product only for its designated purpose. Observe the operating conditions and performance limits stated in the data sheet.

  • Page 17: Getting Started

    The electromagnetic compatibility (EMC) class indicates where you can operate the product. The EMC class of the L4Cc or L6Ccc combiners is “class A”. Class A equipment is intended for use in industrial environments. It can cause radio disturbances in residential environments due to possible conducted and radiated disturbances.

Proper protection measures against laser light shall be enforced To avoid damaging the fiber end face, the following adjustment procedure should be performed at low optical power (50mW or below)
  • Page 58 Increasing the signal Once an optical signal is detected, the power meter’s sensitivity shall be changed accordingly. The next step consists in maximizing the signal’s power by turning the adjustement screws one by one. Start with one adjustment screw and tighten it slowly until the optical signal reaches a relative maximum. Then fasten this first screw a little more so that the signal’s power decreases by a few percents.
