SAFETY INFORMATION
This laser is safe to operate provided that the user complies with all safety warnings. It is
recommended that all personnel who will operate or be in the vicinity of the laser during operation
read and be familiar with this manual as well as be made aware of the following safety warnings.
•Alterations, modifications, or improper installation can result in shock, visible
and/or infrared radiation exposure, and void of the warranty in part or entirety.
•Ensure that the laser head is securely connected to the power supply. To
prevent faulty operation make sure that the male connector is fully
seated in the back of the power supply.
•The helium neon laser can collect charge during operation acting as a
capacitor. Once the power supply is turned off, best practice is to leave
the high voltage cable connected to the power supply. If the high voltage
cable is removed from the power supply the prongs should be shorted

REF-177

together to discharge any remaining energy. A way to accomplish this is
to simultaneously touch both prongs to a conductor.
•Do not attempt to open the sealed laser housing or the power supply.
The power supply and laser is not user accessible and service operations
inside the enclosure must only be performed by authorized and trained
personnel. Opening the laser or power supply will result in loss of
warranty.
•Avoid direct exposure to the laser beam.
•Laser emissions can be hazardous to the eyes.
•Never look directly into the laser light source or at scattering laser light
from reflective surfaces.
•Never sight down the beam into the source of the laser emissions.
•Install the laser so that the laser beam is not at eye level.
•Whenever the laser is operating and the beam is not in use, block the
beam with the shutter on the output aperture.
•As a precaution against accidental exposure to either the laser beam or
its reflection, operators need to wear laser safety glasses designed for
this type of laser.

Figure 4: Back Panel of Power Supply
Fuse Assembly/Power Cord Installation
The power supply will not operate until the fuse assembly is correctly installed. The enclosed
fuse assembly can be found with a 250V - 5A slow blow fuse installed. A component within this
fuse assembly is the input line voltage selector. The input line voltage selector configures the
correct input line voltage for the local environment. This can be accomplished by sliding the input
line voltage selector into the side of the fuse assembly (Figure 5). The desired input line voltage
can be seen right side up in the window on the face of the fuse assembly. Select the proper voltage
for your region of the world. Once the correct line voltage is selected, insert the fuse assembly into
the power cord connector located on the back of the unit. The fuse assembly will be flush with the
face of the AC connector when properly installed.
Note: Use only 250V-5A slow blow fuses with this product (5mm dia x 20mm length). Failing to
select the correct input line voltage will result in failure of the unit and will void the warranty.
Figure 5: Configuring Input Line Voltage Selector

REF-177

Once the fuse assembly and voltage selector are correctly installed, insert the supplied US
IEC320 Female to Nema 5-15P power cord into the power supply unit. To ensure proper and
optimal laser operation, only use the power supply that is appropriate for the HeNe laser head in
use.
Figure 6: Confirming Selected Voltage
Fuse Replacement
To remove the fuse assembly, insert a flat blade screw driver into the groove on top of the fuse
assembly and carefully remove from the power cord connector. Remove the fuse and replace with
a 250V-5A slow blow fuse (Fuse Type 2AG). While replacing the fuse assembly as described above,
ensure that the input voltage selector is still properly configured.
Remote Interlock Operation
To use the remote interlock connector, remove the shorting conductor from the connector
provided. The connector may then be wired into the interlock system. The circuit is designed to
activate the laser output when the two contacts of the connector are shorted together. This can be
achieved via a simple switch or with relay contacts.
The voltage on this connector is nominally 5VDC and is generated internally within the power
supply unit. It is completely isolated from the AC line voltage. Failure of the remote interlock
feature due to improper application of external voltages is not covered by warranty.
Operating Procedures
The system is equipped with a key switch located on the front panel. This is used by the
customer to activate and deactivate the laser. The emissions indicator on the front panel will come
on to warn of imminent laser emission. A 10-15 second delay will begin after the key switch is
turned to the “ON” position. The laser system will be “OFF” when the key is in the vertical position.
The laser emissions can be controlled from the remote interlock connector. If the factory
supplied remote interlock plug is removed while the laser is in operation, laser emissions will cease
immediately. If the remote interlock plug is inserted into the remote interlock connector, laser
emissions will resume after a 10-15 second safety delay. If the remote interlock connector has
been interfaced to external circuits, laser emissions will be controlled in a similar manner.
•The system will start within 10-15 seconds after engaging the key switch.
•Laser intensity will stabilize at or above the specified power output after thirty minutes of
continuous operation.
•Open the beam shutter located on the laser head at the output of the laser (indicated by
the arrow on the aperture label).

Maintenance & Service
The power supply unit contains no user serviceable parts. Return the power supply unit to
Newport for any service issues that may arise.
OPERATING INSTRUCTIONS FOR LASER HEAD WITH POWER SUPPLY
The cylindrical construction of the laser head allows for easy mounting in ring clamps, V-blocks,
or similar mounting hardware without affecting the laser's alignment. Use caution when clamping
onto the laser as too much pressure can damage the aluminum housing or cause misalignment.
The front bezel has four each 4-40 Unified National Coarse Thread (UNC) holes to secure an
optional accessory mounting ring. The ring (part number R-30646), which is available for purchase
from Research Electro-Optics, has 1" diameter, 32 threads-per-inch (TPI) female threads.
Installation
Laser system includes a laser head and a power supply.
•Configure the AC power supply as directed in the “Operating Instructions for Power
Supplies” section above.
•Insert the remote interlock connector into the back of the power supply.
•Plug the two prong high voltage cable from the laser into the front of the power supply.
Confirm that the plug is well seated.
•Insert the key into the front panel of the power supply.
BASIC TROUBLESHOOTING
Once the laser and power supply have been properly connected, the laser system will operate
without maintenance. Below are some guidelines if your system is not operating. When
troubleshooting take all precautions as if the laser system is fully operational.
