1 Introduction
Thank you for choosing CAVILUX Smart!
CAVILUX®Smart is a Finnish quality product developed and manufactured by Cavitar Ltd.
We hope that you will be satisfied with your product.
CAVILUX Smart is a versatile, accurate, reliable and easy-to-use pulsed high power diode
laser light source designed especially for the visualization of challenging processes in
scientific and industrial R&D. CAVILUX Smart enables the continuous real-time
measurement of several different process parameters such as morphology, homogeneity,
track, velocity and acceleration.
CAVILUX Smart suits especially well for the visualization of small, fast and/or hot objects.
Since CAVILUX Smart provides high temporal accuracy and speed, the camera can be
chosen rather freely according to the requirements of the process. For example, it is possible
to use a low frame rate and high resolution camera for continuous online process monitoring
and control.
Please read this operating manual carefully before using CAVILUX Smart.
Chapter 2 contains important safety information for the safe operation of CAVILUX Smart.
Chapter 3 describes the properties of CAVILUX Smart and Chapter 4 deals with the
installation of the system.
Chapter 5 describes the operation of CAVILUX Smart. Please note that there is plenty of
useful information related to the use of CAVILUX Smart in Section 5.4. As an example,
troubleshooting is covered in Section 5.4.7.
Chapters 6 to 8 cover issues related to maintenance, service, support, accessories and
warranty.
The symbols below will be utilized throughout this operating manual:

2 Safety information
PLEASE CAREFULLY READ AND UNDERSTAND THE FOLLOWING SAFETY
INSTRUCTIONS BEFORE USING CAVILUX SMART. IT IS OF UTMOST
IMPORTANCE TO STRICTLY OBEY THESE INSTRUCTIONS. OTHERWISE SERIOUS
DAMAGE TO THE USER OR TO THE DEVICE MAY OCCUR.
ONLY A PERSON, WHO HAS CAREFULLY READ AND UNDERSTOOD ALL SAFETY
INSTRUCTIONS BELOW AND THE REST OF THIS OPERATING MANUAL, IS
QUALIFIED FOR USING CAVILUX SMART. CAVITAR LTD. IS NOT LIABLE FOR
ANY DAMAGE CAUSED BY THE IMPROPER USE OF CAVILUX SMART.
CAUTION--USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF
PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT IN
HAZARDOUS RADIATION EXPOSURE.
CAUTION--USE OF OPTICAL INSTRUMENTS WITH THIS PRODUCT WILL
INCREASE EYE HAZARD.
WARNING!
CAUTION!
•CAVILUX Smart is a class 4 laser product.
olaser class is indicated by the yellow warning label on top of the laser unit
possible warning labels are shown above. Warning text depends on
whether the output wavelength is 690 nm (the warning label on the left)
or 810 nm (the warning label on the right)
olaser apertures on the laser unit and on illumination optics are indicated by
yellow aperture labels (see the label above)
•Do not look into the direct, reflected or scattered laser beam!
o690 nm laser unit emits visible red laser light at 690 ± 10 nm wavelength band
o810 nm laser unit emits invisible laser light at 810 ± 10 nm wavelength band
owear suitable laser safety goggles (always ensure that the goggles protect
especially for the emission wavelength band of the laser!)
•The accidental exposure to direct/reflected/scattered laser beam has to be prevented:
outilize suitable casings, curtains, beam blockers/absorbers, closed doors,
Remote Interlock (RIL) feature and warning plates/lights/sounds in such a way
that no one can enter the region of potential laser exposure by accident
opay special attention to possible bystanders or persons passing by
oensure that the key is removed from the control unit after use

•Before turning the device on, make sure that (in addition to the instructions above):
oeveryone inside the region of potential laser exposure wears laser safety
goggles that block laser radiation at 690 ± 10 nm and/or at 810 ± 10 nm
othe laser output and laser light blockers/absorbers are aligned and positioned in
such a way that the direct/reflected/scattered laser beam will not be dangerous
to anyone
•If the laser is to be used at high duty cycle and if the beam is to be focused tightly, the
possible risk of fire or explosion in the presence of flammable materials has to be
taken into account
•Ensure that there is no risk of unintentional voltage signal/peak (e.g. static discharge)
at the Set Mode I/O (SMIO) connector, since this may enable/disable laser output (see
Chapter 3 for more information)
•Other instructions:
oDo not make ANY modifications to the device by yourself CAVILUX Smart is not certified for medical use
oDo not try to repair the device by yourselfo
oIt is strictly forbidden to open the cover of the laser unit or the control unit.
Otherwise serious damage or injury to the user or to the device may occur.
Laser unit contains gallium arsenide, which is a known human carcinogen
oDo not expose the system to moisture, rain or condensing environment Before turning the device on, ensure that all connections are properly made
oExcessive vibration or strong mechanical impact may damage the equipmento
oThe operating temperature of CAVILUX Smart is +10…+40 °C. Do not
expose CAVILUX Smart to excessively low or high temperatures
oIf you are uncertain about any issue related to safety or proper operating
conditions, please contact your vendor or Cavitar
