INTRODUCTION PAGE |11
Introduction
This section contains the following information:
•Series 48 Trademark, Copyright & Warranty information
•Series 48 guidelines and contents description
•Series 48 Nomenclature
Important Note: This Operation Manual explains operation activities related to Series 48 lasers. If
you cannot operate the unit using the information described in this manual, contact NOVANTA®
(+1.425.349.3500) or an authorized NOVANTA Distributor.
The Quick Start Guide (QSG) Quickstart explains how to quickly unpack and assemble Series 48 lasers.
Please reference the QSG along with the information within this manual.
Lift the laser only by the mounting feet or baseplate. Do not lift or support the laser by its cooling fittings.
Please reference the Quick Start Guide for unpacking, mounting, and connecting.
Warning: Serious Personal Injury
Remote interlock faults are not latched on OEM lasers. Clearing the fault condition re-enables the
RDY indicator and the laser will bee enabled five seconds after the SHT indicator is lit and a PWM
Command signal is applied.
Because exposure to CO2 laser radiation in the (9-11) μm range can inflict severe corneal injuries and
seriously burn human tissue, the OEM or System Integrator must ensure that appropriate safeguards
are in place to prevent unintended lasing.
Caution: Possible Equipment Damage
NOVANTA does not recommend vertical or head down configurations.
Please contact the factory for limitations as a vertical orientation increases the risk of damage to the
lasers optics.
A
risk of exposure
to toxic elements may result when certain optical or beam delivery components
are damaged. In the event of damage to laser, marking head, or beam delivery optics, contact
NOVANTA®, or the optics manufacturer for handling instructions.
If you
operate your laser dirty or dusty environments
, contact NOVANTA about the risks of doing
so and precautions you can take to increase the longevity of your laser, marking head, and associated
optical components.

HAZARD INFORMATION PAGE |17
•Important note: Content specific information and/or recommendations.
Read the entire safety section. This will ensure you are familiar with the hazards and warnings prior to
starting.
A CO2 laser is an intense energy source and will ignite most materials under the proper conditions. Never
operate the laser in the presence of flammable or explosive materials, gases, liquids, or vapors.
Safe operation of the laser requires the use of an external beam block to safely block the beam from
traveling beyond the desired work area. Do not place your body or any combustible object in the path of
the laser beam. Use a water-cooled beam dump or power meter, or similar non-scattering, noncombustible
material as the beam block. Never use organic material or metals as the beam blocker; organic materials,
in general, are apt to combust or melt and metals act as specular reflectors which may create a serious
hazard outside the immediate work area.
48 Series lasers should be installed and operated in manufacturing or laboratory facilities by trained
personnel only. Due to the considerable risks and hazards associated with the installation and operational
use of any equipment incorporating a laser, the operator must follow product warning labels and
instructions to the user regarding laser safety. To prevent exposure to direct or scattered laser radiation,
follow all safety precautions specified throughout this manual and exercise safe operating practices per
ANSI Z136.1-2014, Safe Use of Lasers at all times when actively lasing.
Due to the specific properties of laser light, a unique set of safety hazards that differ from other light
sources must be considered. Just like light, lasers can be reflected, refracted, diffracted, or scattered.
Warning: Serious Personal Injury
For laser systems being used or sold within the U.S.A., customers should refer to and follow the laser
safety precautions described American National Standards Institute (ANSI) document Z136.1-2014,
Safe Use of Lasers.
For laser systems being used or sold outside the U.S.A., customers should refer to and follow the laser
safety precautions described in European Normative and International Electrotechnical Commission
documents IEC/ TR 60825-14:2014, Safety of Laser Products – §14: A User’s Guide.
Warning: Serious Personal Injury
The use of controls or adjustments or performance of procedures other than those specified herein
may result in hazardous radiation exposure.

DISPOSAL PAGE |18
Following are descriptions of general hazards and unsafe practices that could result in death, severe injury,
or product damage. Specific warnings and cautions not appearing in this section are found throughout
the manual.
Disposal
This product contains components that are considered hazardous industrial waste. If a situation occurs
where the laser is rendered non-functional and cannot be repaired, it may be returned to NOVANTA® who,
for a fee, will ensure adequate disassembly, recycling and/or disposal of the product.
Other hazards
The following hazards are typical for this product family when incorporated for intended use:
Warning: Serious Personal Injury
Do not allow laser radiation to enter the eye by viewing direct or reflected laser energy.
CO2 laser radiation can be reflected from metallic objects even though the surface is darkened. Direct
or diffuse laser radiation can inflict severe corneal injuries leading to permanent eye damage or
blindness. All personnel must wear eye protection suitable for CO2 radiation, e.g., 9.3–10.6 μm when in
the same area as an exposed laser beam.
Eye wear protects against scattered energy but is not intended to protect against direct viewing of
the beam— never look directly into the laser output aperture or view scattered laser reflections from
metallic surfaces.
Enclose the beam path whenever possible. Exposure to direct or diffuse CO2 laser radiation can
seriously burn human or animal tissue, which may cause permanent damage.
This product is not intended for use in explosive, or potentially explosive, atmospheres!
Materials processing with a laser can generate air contaminants such as vapors, fumes, and/or
particles that may be noxious, toxic, or even fatal. Safety Data Sheets (SDS) for materials being
processed should be thoroughly evaluated and the adequacy of provisions for fume extraction,
filtering, and venting should be carefully considered. Review the following references for further
information on exposure criteria:
ANSI Z136.1-2014, Safe Use of Lasers, § 7.3.
U.S. Government’s Code of Federal Regulations: 29 CFR §1910, §§ Z.
Threshold Limit Values (TLV’s) published by the American Conference of Governmental Industrial
Hygienists (ACGIH).
It may be necessary to consult with local governmental agencies regarding restrictions on the venting
of processing vapors.
The use of aerosol dusters containing difluoroethane causes “blooming,” a condition that significantly
expands and scatters the laser beam. This beam expansion can affect mode quality and/or cause
laser energy to extend beyond the confines of optical elements in the system, possibly damaging
acrylic safety shielding. Do not use air dusters containing difluoroethane in any area adjacent to CO2
laser systems because difluoroethane persists for long time periods over wide areas.

THORIUM SAFETY PAGE |19
(A) risk of injury when lifting or moving the unit; (B) risk of exposure to hazardous laser energy through
unauthorized removal of access panels, doors, or protective barriers; (C) risk of exposure to hazardous
laser energy and injury due to failure of personnel to use proper eye protection and/or failure to adhere
to applicable laser safety procedures; (D) risk of exposure to hazardous or lethal voltages through
unauthorized removal of covers, doors, or access panels; (E) generation of hazardous air contaminants
that may be noxious, toxic, or even fatal.
Thorium Safety
•This laser system incorporates a II-VI Infrared optical component.
•This optical component contains a small amount of thorium fluoride, a type of source material (less
than 10% by weight).
•It is exempt from USNRC licensing regulations as an “unimportant quantity of source material” per
10 CFR 40.13(c) (7).
•Shaping, grinding, polishing, or alteration of the optical component is prohibited.
•Use of this optical component in contact lenses, spectacles, or in eyepieces in binoculars or other
similar optical instruments is prohibited.
Cleaning optical components is permitted so long as care is taken not to damage the coated surface of
the component as sold.
This II-VI Infrared requirement only applies to lenses and optics manufactured and distributed by II-VI
Infrared. Distributing components or devices that contain lenses and optics manufactured by other
companies as if it were manufactured by II-VI Infrared is not in compliance with USNRC distribution
requirements.
U.S. distribution of components or devices that contain lenses and optics manufactured by other
companies which contain uranium and/or thorium requires a USNRC distribution license. Only II-VI Infrared
manufactured lenses and optics which contain thorium are covered by the II-VI Infrared distribution
license.
10 CFR 40.13(c) (7) Unimportant quantities of source material.
(7) Thorium or uranium contained in or on finished optical lenses and mirrors, provided that each lens or
mirror does not contain more than 10 percent by weight thorium or uranium or, for lenses manufactured
before August 27, 2013, 30 percent by weight of thorium; and that the exemption contained in this
paragraph does not authorize either:
(i) The shaping, grinding, or polishing of such lens or mirror or manufacturing processes other than the
assembly of such lens or mirror into optical systems and devices without any alteration of the lens or
mirror; or
(ii) The receipt, possession, use, or transfer of uranium or thorium contained in contact lenses, or in
spectacles, or in eyepieces in binoculars or other optical instruments.
