4.0 Laser Safety
4.1 A Note Regarding Compliance
The Vortran Stradus VersaLase™ OEM System has features which allow it to be
easily integrated a system which meets CDRH safety requirements, based on
EN60825-1. These features include the interlock, emission LEDs, 5 second
emission delay.
4.2 Laser Classification
The Stradus VersaLase™ is classified as a Class IIIb laser device as specified
by the Center for Device and Radiological Health (CDRH). The device emits
visible or invisible laser radiation from the aperture located in the front of the
laser system chassis. The emitted wavelength(s) and maximum power level(s)
are specified on the laser safety label.
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.
4.4 Laser Safety Labels
Figure 1
Laser Safety Label

www.vortranlaser.com
4.5 Electrical Safety
No hazardous voltages are contained in the Stradus VersaLase™ laser head.
The system does not contain any user accessible components within the system
enclosure. The warranty will void if the enclosure is disassembled.
ESD
Vortran Laser Technology recommends that proper ESD precautions are taken
when handling the laser head. The Vortran Stradus VersaLase™ System is
designed with internal safeguards for protection against 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. The user is advised to wear appropriate safety eyewear for the
wavelength(s) and power level(s) of lasers in their application. 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 prior to
laser exposure. The laser emission indicators located on the laser head are
visible even when using laser safety eyewear.
4.7 Vortran Laser Safety Features
4.7.1 Protective Housing – The Stradus VersaLase™ is enclosed in a
protective metal housing. This housing is not intended to be removed by
the user as there are no user-serviceable parts inside the module. If the
housing is removed, the user may be exposed to laser radiation and
electrical shock hazards and all warranties will be void. 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 – A power indicator, shown in Figure 3 below, is located
on the rear panel of the chassis. This indicator is visible even when using
laser safety eyewear.

Figure 2
Power Indicator
4.7.3 Interlock- The Stradus VersaLase™ features safety interlock circuitry
which must be closed electrically for laser emission to occur. The electrical
interlock is available at the DE-25 25-pin connector on the rear panel. More
information about the interlock may be found in the Section 6 or 7 of this manual.
Figure 3
Interlock Diagram
4.7.4 Laser Emission Indicators – The Stradus VersaLase™ module includes
emission indicators to indicate emission from each laser module enclosed in the
chassis. The wavelength of the indicators allows them to be viewed when using
laser safety eyewear. The laser emission indicators will illuminate prior to laser
emission and during laser emission. The laser system should be considered
dangerous when the emission indicators are active.

Laser Emission Indicators
4.7.5 Computer Control – The Stradus VersaLase™ may be controlled by a
computer via USB or RS-232 connections. The status of safety features
such as the electronic laser emission interlock may be monitored by
firmware terminal commands and queries or by using the Stradus
VersaLase™ user interface software.

5.0 System Information
5.1 System Features
Compact full-featured multi-laser platform with a common control interface
USB or RS-232 remote communication
Control and monitoring available through Stradus VersaLase™ Software
External Analog Power Control (if equipped)
Digital Modulation Control (if equipped)
Field-upgradable multi-laser platform
5.2 System Description
The Vortran Stradus VersaLase™ provides a compact, full-featured, field
upgradeable, multiple laser platform with a common hardware and software
control interface for all lasers in the package. The multiple laser system includes
visible indicators for power and laser emission for each wavelength.
5.3 Power Supply Requirements and Protection
12V +/- 10% (10.5V to 13.5V) at 9 amps
It is recommended that the Stradus VersaLase™ ground is connected to a power
supply which has a connection to Earth ground. Many “brick” style power
supplies do not provide this connection.
5.4 Environmental Operating Conditions
The Vortran Stradus VersaLase™ module is designed for indoor or enclosed use
only. Typical operating temperatures range from 10ºC to 40ºC, based on the heat
sink used to maintain base plate temperatures at or below 50ºC. The Vortran
Stradus VersaLase™ laser can operate at altitudes up to 2000 meters.
Maximum relative humidity is 80% for ambient temperatures up to 31ºC, with a
linear decrease to 50% at 40ºC. The laser system does not emit any type of
pollution.

System Dimensions
6.3.2 Heat Sink Requirements
The Stradus VersaLase™ system is conduction-cooled and requires a heat sink
for operation.
Failure to use a heat sink will overheat the module
Heat sink compound is not required or recommended for mounting.
A heat sink capable of dissipating 75 Watts is required for
laser mounting.
A 32 finish is recommended for the system mounting surface, to
ensure optimum thermal transfer.
A high tolerance heat sink surface flatness is recommended
for mounting.
6.3.3 Laser Mounting Hardware
Recommended mounting hardware for the Stradus VersaLase™ system is
M6 x 6mm or ¼ - 20 x ¼”.

6.3.4 Torque Specifications
Normal mounting can be accomplished by using the provided hex
key to secure the laser head to the heat sink, by tightening the screws
gradually in a progressing cross pattern. This method should provide
stable thermal and pointing performance. Optimum thermal and pointing
performance is accomplished by securing the laser head to the heat sink,
with a precision torque driver. Torque the laser module to the heat sink by
using a cross torque pattern and progressively increasing torque from
10in-lbs to 15-in-lbs to 20in-lbs. Torque the module in the sequence
shown below.
