Laser Safety and Regulations
While lasers are valuable sources of light for exciting demonstrations,
laboratory experiments and industrial use, one must treat lasers
and high voltage power supplies with the utmost respect. One should
familiarize oneself with the components before attempting any
assembly. Our lasers are sold as components only, when assembled
into working systems they must incorporate the safety requirements
set forth by the Center for Devices and Radiological Health of
the Food and Drug Administration (C.D.R.H.).
Laser Safety
Common sense dictates that one should avoid direct skin and eye
exposure to laser energy as well as surface reflections. Diffuse
reflections from higher power lasers can be just as dangerous
as direct exposure. Please contact the C.D.R.H. for complete guidelines
on laser safety. Many books also exist on laser safety, please
check your local library.
High Voltage Warning
Helium-Neon lasers require high voltage power supplies to sustain
lasing action. These power supplies are much like that found in
television sets. Typical voltages employed range from 1400 - 3400
VDC and with trigger pulses from 8 - 16 Kilovolts. The typical
current outputs of these supplies range from 4 - 15 milliamps.
These supplies if mishandled can be LETHAL. If you are not familiar
with high-voltage dangers, do not attempt to utilize these supplies
until you are familiar with the dangers.
C.D.R.H. Regulations
When assembled for use in the United States, ALL lasers must comply
with the safety regulations set forth by the Center for Devices
and Radiological Health of the Food and Drug Administration. The
C.D.R.H. classifies lasers by their power levels and specifies
appropriate safety features for each classification. Detailed
information can be obtained by contacting: Office of Compliance,
HSZ 300, Gaither Road, Rockville, MD 20850, (301) 594-4654
Please - Be safe, not sorry!
