NOMENCLATURE PAGE |14
Nomenclature
The nomenclature section includes:
•Model numbers
•Laser versions
The first three characters designate the Model Series, second three characters indicate the power option,
the next character signifies the safety option which is an “S” (Standard) for OEM models. The next
character indicates the model revision or laser build and the last three characters indicate the beam
options where 10.6 is 10.6um.
Refer to the following figure for further examples.
Laser versions
p250 lasers are divided into two distinct functional categories: Keyswitch and OEM models. In addition
to a manual Keyswitch for resetting faults, all Keyswitch-equipped lasers incorporate a manual shutter
switch to block the laser’s output aperture as an added safety measure.
NOVANTA© OEM lasers are primarily designed as components for integration into larger processing
systems by the Original Equipment Manufacturer (OEM) or System Integrator who bears the
responsibility for meeting the appropriate laser safety requirements for Class 4 laser systems.
p250 lasers are currently available only as OEM lasers; however, they do include an EM shutter assembly.
Caution: Possible Equipment Damage
Do not use more than one fastener per foot, otherwise damage to your laser will occur!

band.
Because direct or diffuse laser radiation can inflict severe corneal injuries, always wear eye protection
when in the same area as an exposed laser beam.
Do not allow the laser beam to contact a person!
This product emits an invisible laser beam that is capable of seriously burning human tissue.
Always be aware of the beam’s path and always use a beam block while testing.

TERMS PAGE |17
•Important Note: Content specific information and/or recommendations.
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.

GENERAL HAZARDS PAGE |18
General hazards
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.
p250 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
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.

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:

ADDITIONAL LASER SAFETY INFORMATION PAGE |20
(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.
