WELCOME TO BEA LASERS
The highest quality laser diode modules at a reason-
able cost – this is our commitment to you. Our team
of applications engineers and sales associates, with
many years of experience in the field of optics and
photonics, will work closely with you to find a solution
– customized or from stock – that meets your needs.
BEA Lasers are available nationwide. Our warehouse
is in suburban Chicago and ships your components
as ordered and on time.
Since 1980, BEA has been committed to offering
solutions to industry and research. Many products
conform to and surpass the standards of CE and FDA,
so your products benefit from the quality that goes
into our laser diode modules.
About Laser Diode Modules
Our laser diode modules feature a rugged, compact
design that is suitable for industrial or laboratory uses.
Heat dissipation is handled by passive radiation
through the case and mounting bracket. Integrated
electronics protect the diode from reverse wiring and
line noise that would otherwise destroy it.
About Lenses
Adjustable focus allows you to project the sharpest
beam pattern possible: this is critical for projecting lines
and crosshairs. Glass lenses will render a more uniformly
focused beam pattern than plastic ones. Plastic lenses,
however, are lower in cost and may be sufficient for
some applications.
Red and Green Laser Considerations
The human eye perceives the light emitted from a 1mW
670nm laser as bright. Laser light at 650nm is perceived
as brighter, and 635nm is seen as the brightest red.
Green laser light at 1mW 532nm is clearly perceived
as the brightest laser diode module light.
Customization
Other available wavelengths include Blue and Infrared.
Caseless construction can save space inside enclosures.
Driver electronics can support static protection, beam
pulsing, or TTL modulation.

WHATISALASER?
LASER is an acronym which stands for Light Amplification by
Stimulated Emission of Radiation. The energy generated by the laser
is in or near the optical portion of the electromagnetic spectrum (see
Figure 1). Energy is amplified to extremely high intensity by an atom-
ic process called stimulated emission. The color of laser light is nor-
mally expressed in terms of the lasers wavelength. Nanometer (nm)
is the most common unit used in expressing a lasers wavelength.
LASER HAZARDS & BEAM HAZARDS
The laser produces an intense, highly directional beam of light.
If directed, reflected, or focused upon an object, laser light will be
partially absorbed, raising the temperature of the surface and/or the
interior of the object, potentially causing an alteration or deforma-
tion of the material. Lasers can also cause tissue damage. Today, most
high-power lasers are designed to minimize access to laser radiation
during normal operation. Lower-power lasers may emit levels of laser
light that are not a hazard.
LASER HAZARDS CLASSIFICATION
The Center for Devices and Radiological Health, a division of the
Food and Drug Administration regulates the manufacturing and
classification of laser products. The laser classes help group lasers
by their hazard potential, and identifies these classes based on their
optical emission (wavelength, exposure time, output power).
GENERAL GUIDELINES FOR
CW LASER CLASSIFICATION
Class I Lasers or laser systems that do not, under normal
operating conditions, pose a hazard.
Class IIa Low power visible lasers or laser systems that are not
intended for prolonged viewing, and under normal operating
conditions will not produce a hazard if the beam is viewed directly
for periods not exceeding 1000 seconds.
Class II Low power visible lasers or laser systems which, because
of the normal human aversion response, do not normally present a
hazard, but may present some potential for hazard if viewed directly
for extended periods of time (like many conventional light sources).
Class IIIa Lasers or laser systems having a CAUTION label that
normally would not injure the eye if viewed for only momentary
periods (within the aversion response period) with the unaided
eye, but may present a greater hazard if viewed using collecting
optics. Another group of Class 3a lasers have DANGER labels and
are capable of exceeding permissible exposure levels for the eye
in 0.25 seconds and still pose a low risk of injury.
Class IIIb Lasers or laser systems that can produce a hazard if viewed
directly. This includes intrabeam viewing of specular reflections. Class
3B lasers will not normally produce a hazardous diffuse reflection.
Class IV Lasers or laser systems that produce a hazard not only from
direct or specular reflections, but may also produce hazardous
diffuse reflections. Such lasers may produce significant skin hazards
as well as fire hazards.
The information mentioned here is intended to be an introduction
to lasers and laser safety, and should not be considered to be an
authoritarian guide. A better informed user has the knowledge to
make safer decisions: learn about safety procedures for your class
of laser, and the next class higher.
An excellent source for laser safety is the Laser Institute of America.
A very useful resource is their web-based Safety Bulletin and printed
Laser Safety Guide.
