1 Basic safety notes
Intended use
The device has been designed exclusively for measurements in the beam of high-power
lasers.
Use for any other purpose is considered as not intended and is strictly prohibited.
Furthermore, intended use requires that you observe all information, instructions, safety
notes and warning messages in this operating manual. The specifications given in chap-
ter15 „Technical data“ on page66 apply. Any given limit values must be complied
with.
If not used as intended, the device or the system in which the device is installed can be
damaged or destroyed. In addition, there is an increased risk to health and life. Only use
the device in such a way that there is no risk of injury.
This operating manual is an integral part of the device and must be kept in the immedi-
ate vicinity of the place of use, accessible to personnel at all times.
Every person who is responsible for the installation, start-up or operation of the device
must have read and understood the operating manual and, in particular, the safety
instructions.
If you still have questions after reading this operating manual, please contact PRIMES or
your supplier for your own safety.
Observing applicable safety regulations
Observe the safety-relevant laws, guidelines, standards and regulations in the current
editions published by the state, standardization organizations, professional associations,
etc. In particular, observe the regulations on laser safety and comply with their require-
ments.
Necessary safety measures
The device measures direct laser radiation, but does not emit any radiation itself. How-
ever, during the measurement the laser beam is directed at the device. This produces
scattered or directed reflection of the laser beam (laser class 4). The reflected beam is
usually not visible.

35,0(6
9
Cube L1
Revision 04 EN - 03/2023
Protect yourself from direct and reflected laser radiation while working with the device
by taking the following measures:
• Never leave the device unattended when taking measurements.
• Wear safety goggles adapted to the power, power density, laser wavelength and
operating mode of the laser beam source in use.
• Wear suitable protective clothing or protective gloves if necessary.
• If possible, also protect yourself from direct laser radiation and scattered radiation
by using separating protective devices that block or attenuate the radiation.
• If the device is moved from its aligned position, increased scattered or directed
reflection of the laser beam occurs during measuring operation. Mount the device
in such a way that it cannot be moved unintentionally, i.e. by bumping or pulling
the cables
• Connect the laser control’s safety interlock to the device. Check that the safety
interlock will switch off the laser properly in case of error.
• Install safety switches or emergency safety mechanisms that allow the laser to be
switched off immediately.
• Use suitable beam guidance and beam absorber elements which do not emit any
hazardous substances when irradiated.
Employing qualified personnel
The device may only be operated by qualified personnel. The qualified personnel must
have been instructed in the installation and operation of the device and must have a
basic understanding of working with high-power lasers, beam guiding systems and
focusing units.
Conversions and modifications
The device may not be modified in terms of design or safety without the explicit consent
of the manufacturer. The same applies to unauthorized opening, dismantling and repair.
The removal of covers is only permitted within the scope of the intended use.
Liability disclaimer
Manufacturer and distributor exclude any liability for damages and injuries which are
direct or indirect consequences of using the device not as intended or modifying the
device or the associated software without authorization.

3 About this operating manual
This manual describes the installation and operation of the CubeL1 and performing
measurements with the CubeL1, the optional Cube App or the optional LaserDiagnos-
ticsSoftware LDS version 1.4 or higher. In this operating manual, the abbreviation LDS is
used.
With the Cube App for mobile devices with Android™ you can operate and evaluate the
device via a smartphone/tablet. The Cube App is available for free in Google Play-Store/
Apps.
For measurement operation with a PC, the optional LaserDiagnosticsSoftware LDS
must be installed on the PC. PRIMES will be happy to provide you with a current down-
load link. For this purpose, contact your sales partner or send an e-mail to:
[email protected]
The software description includes a brief introduction on using the device for measure-
ments. For a detailed description of the software installation, file management and
evaluation of the measurement data, please refer to the separate instructions for the
LaserDiagnosticsSoftware LDS.
This operating manual describes the software version valid at the time of print-
ing. Since the LDS is subject to continuous development, the supplied data
medium may have a newer version number.

4 Device description
4.1 Functional description
The device is used to measure laser power. The laser beam passes through the protec-
tive window and hits the absorber and a photodiode. The absorber and the photodiode
are protected from contamination by the protective window. The display shows the
measured laser power and further information on the status of the device.

4.2 Measuring principle
The device offers a fast, passively cooled power measurement according to the calori-
metric measuring principle.
The absorber of the measuring device is briefly irradiated with the laser beam. The ir-
radiated energy is determined by the temperature rise of the absorber.
The photodiode simultaneously determines the laser ontime. The high-frequency sam-
pling rate of the photodiode enables single pulse detection for pulses not shorter than
50μs.
Thus, in addition to the average power, the peak power can be calculated. In the sec-
ond step, the actual laser power is calculated from the irradiated energy divided by the
laser ontime.

4.4.2 Warning message
Warning message Reason
Safety interlock open The absorber temperature has exceeded 100°C. In order to protect
the device, the safety interlock was triggered.

This warning message does not imply an error. The message is automatically
reset as soon as the absorber temperature is below 100°C again. The safety
interlock is then also automatically switched back to the permissible operating
status.

Revision 04 EN - 03/2023
4.6.1 Charging the lithium-ion battery
Charge the battery completely before using the device for the first time. The first com-
plete charge on the PC requires approx. 3hours. Only use the supplied USB cable to
charge the battery. Recharge the battery when the charge level reaches 20%. Do not
charge the rechargeable battery unattended, e.g. overnight. Do not expose the device
to direct sunlight.
4.6.2 Storing the device with a permanently installed lithium-ion battery
Store the device in a cool, dry place. Keep a minimum distance of 3 m from combus-
tible materials. Do not expose the device to direct sunlight. Please charge the battery at
least every three months.
4.6.3 Dangers to health and the environment in the event of damage to the
lithium-ion battery
In general, contact with leaking battery components may pose a hazard to health and
the environment:
• When the battery is damaged, fluids (electrolytes) may leak out. These are flam-
mable, contact with the eyes or skin may cause irritation.
• Vapors may irritate the eyes, respiratory organs, and skin.
• Fire or intense heat may cause violent bursting. Heating or fire may release toxic
gases. Burning produces irritating smoke.
4.6.4 Charge status of the lithium-ion battery
The charge status of the battery is displayed in %. The accuracy of the display depends
on various factors (e.g. temperature, age of the battery, etc.).
The battery has a capacity of 1000mAh. The battery can be charged with a max.
charging current of 1.3 A via the supplied USB cable. At a charging current of 1.0A,
the charging time is approx. 1hour. At a charging current of 0.5A, the charging time is
approx. 2.5hours.
At 100% charge status, the possible operating time is approx. 6hours (equivalent to
approx. 100measurements). When using all power saving functions (see section „Pow-
er saving functions“ in chapter10.3.3 „Settings in the device control“ on page44)
approx. 15hours.
