4.0 Laser Safety
4.1 Compliance Standards
The Vortran Stradus™ Laser complies with CDRH safety requirements, based on
EN60825-1. The compliance is based on use with the Vortran Stradus™ Control
box. The control box contains the key switch, interlock and Emission LED
required for compliance. Secondary power and laser emission indicators are
located on the laser rear plate. The Vortran Laser CDRH accession number is
on file and available upon request.
The Vortran Laser has been tested and certified by an outside testing agency, to
comply with the following directives:
EMI Standard EN61326-1 Including:
EN55011 Class A radiated emissions
EN55011 Class A conducted emissions
EN61000-3-2 Power Line Harmonics
EN61000-3-3 Power Line Flicker
EMC Standard EN61326-1 Including:
EN61000-4-2 ESD
EN61000-4-3 Radiated Immunity
EN61000-4-4 Electrical Fast Transient
EN61000-4-5 Electrical Surge (L-L and L-E)
EN61000-4-6 Conducted Immunity (Power / I/O Lines)
EN61000-4 11 Power Line Dips and Brown Outs
LVD – Low Voltage Directive 73/23/EEC Including:

4.2 Vortran Laser Classification
The Vortran laser conforms to Class IIIb requirements as specified by the Center
for Device and Radiological Health (CDRH). The Vortran laser emits visible or
invisible laser radiation from the aperture located in the front of the laser head.
The emitted wavelength and maximum power level are specified on the laser
safety label. The typical divergence for all Vortran Stradus™ lasers is 0.5mrad.
4.3 Observations
If the equipment is used in a manner not specified by Vortran Laser Technology,
the protection provided by the equipment may be impaired.

4.5 Electrical Safety
No hazardous voltages are contained in the Vortran laser head. The system
does not contain any user accessible components within the laser head or
control box. The warranty will void if the laser head or control box enclosures are
disassembled.
ESD
Vortran Laser Technology recommends proper ESD precautions are taken when
handling the laser head and control box. The Vortran Stradus™ Laser System is
designed with internal safeguards for protection from ESD. Even with the tested
design safeguards in place, high energy ESD discharge events may cause
damage to the laser system. Vortran Laser Technology recommends handling
and operating the laser system on a grounded work bench or optical table.
4.6 Optical Safety
Based on the properties associated with laser light, special optical safety
precautions are recommended by Vortran Laser Technology. Direct eye
exposure from the laser light emitted from the output aperture located on the
front of the laser head is considered dangerous. Vortran Laser Technology
recommends the use of proper laser safety eyewear when operating the laser
system. Please verify the wavelength of the laser being used and the
wavelength of laser eyewear is appropriate for the laser. The laser output should
be contained in a secure beam path. The user should be aware of propagation
associated with reflective and refractive optical components to be known prior to
laser exposure. The laser emission indicators located on the control box and
laser head, emit wavelength visible when using the proper laser safety eyewear.
Exercise caution when operating the laser with laser safety eyewear in place.
The use of laser safety eyewear provides additional protection to the user. This
use can eliminate the ability to see the beam path when the laser shutter is
open. Vortran Laser Technology recommends that all optical setups are
constructed at levels well below eye level for optical safety reasons.

4.7 Vortran Laser Safety Features
4.7.1 Protective Housing – The Vortran Laser Head and Control box include a
protective housing. These housings are not intended to be removed by
the user and the warranty will be voided if user removal occurs. If the
housing is removed, the user may be exposed to laser radiation or line
voltage. Please return the laser or control box to the factory for any
required repair or service. The factory contact information is located at
the end of this manual.
4.7.2 Power Indicator – Power indicators are located on both the laser head
and control box. With the laser head connected to the control box, power
indicators will illuminate with the control box power switch in the “On”
position. These indicators are visible when using laser safety
eyewear. Please note the location of the power indicators on the
following images.

4.7.3 Interlock Indicator – Two types of laser emission indicators are provided
by Vortran Laser Technology. The Vortran Stradus™ Control Box
Includes an Interlock Indicator. When the power switch is in the “ON”
position and the key switch is set to the “ON” position, the interlock
indicator will be illuminated. This is an indicator of interlock status only
and may not be a direct indicator of active laser emission. When the
indicator is active, laser emission is possible and the laser head should
be considered dangerous.
Laser emission is not possible if the key switch is in the “OFF”
position.
The interlock status is constantly monitored and reported by the
microprocessor in the laser head.
Computer accessible interlock status can be monitored continuously with
the Vortran Stradus™ Control software (Review the Software Section
for additionaliInformation). The interlock status is also accessible
with the ?IL query via RS-232 or USB.

4.7.4 Remote Interlock Operation – The laser control box includes a jack on
the rear panel for remote interlock operation. The Vortran Stradus™
Laser System is shipped with a mating plug for a remote interlock
connection. When the plug is installed and the plug connection is open,
laser emission is not possible. When the plug connection is installed and
closed and the key switch is in the “ON” position, laser emission is
possible.
THE REMOTE INTERLOCK PLUG IS NOT REQUIRED FOR NORMAL
LASER OPERATION

4.7.6 Laser Emission Indicator – The Vortran Laser Head includes a laser
emission indicator. The wavelength of the indicator allows it to be viewed
when using laser safety eyewear. The laser emission indicator is

controlled by the Vortran Laser microprocessor in the laser head and
will illuminate prior to laser emission, when the 5 second CDRH
delay is active. The indicator will be active when power is applied
and the interlock is closed and no fault conditions exist. Unlike the
Interlock Indicator, the Laser Emission Indicator does provide a direct
indication of laser emission and the laser head should be considered
dangerous when the indicator is active.

Laser Emission Indicator
4.7.7 Shutter – The slide operation of the Vortran Laser Shutter, provides the
ability to block the laser output when the emission status is active. The
shutter includes a detent to ensure the shutter remains in the fully
open or closed position. The shutter design ensures no laser light
will be emitted in the closed position. The laser top label provides
indication for the open and closed position. The shutter operates with
a horizontal sliding motion.

4.7.8 Key Switch – The Vortran Laser Key Switch provides the ability to initiate,
halt or prevent laser emission. With the power on and the key switch in
the “ON” position, laser emission is possible. Possible laser emission
