SAFETY
Electrical
Lasercheck has been designed as a sealed and enclosed system. Voltages to operate the measurement sensor
are low (0 to +5 Volts) to minimize shock hazard.
Laser
The laser used in Lasercheck is a class II laser device. Class II lasers are not considered hazardous to the skin but
are considered a “chronic viewing hazard”. Users should not stare directly into the beam or directly into the
beam reflected off a smooth specular surface. The ends of the Laserc
heck measurement sensor have “Caution”
and “Avoid Exposure” labels to remind the operator to avoid exposure to the radiation. The sensor also has
“Identification” and “Certification” labels. The Lasercheck control unit also has "Identification” and
“Certification” labels. Reproductions of these labels are shown below.
Caution
–
use of controls or adjustments or performance or procedures other than those specified herein may
result in hazardous radiation exposure.
The measurement sensor emits a red visible (650-
nm) laser beam pulsing at a 10 to 50 Hz. Each “pulse” contains
as much as 90 microjoules of energy. Pulses can be as short as a 5 millisecond interval, with 20 microsecond rise
and fall times. Maximum “peak” power can be as high as 2.0 milliwatts
. Average maximum power being
emitted from the laser can be as high as 900 microwatts. Once the beam strikes the measurement surface, the
laser energy is reflected back into the Lasercheck detection system. However, multiple reflections and stray
light may exit from between the sensor and measurement surface and care should be taken to avoid direct eye
exposure to the radiation.
