Laser Safety Exam with complete
solutions
Which part of the electromagnetic spectrum do lasers not operate?
visible light
ultraviolet light
x-ray
infrared light - Correct Answers -x-ray
Laser that commonly uses solid material in the active medium:
helium-neon
Nd:YAG
argon
CO2 - Correct Answers -Nd:YAG
monochromatic nature of laser light refers to:
laser light that can be white
laser light that consists of only one color or wavelength
laser light that is very bright
laser light that can emit chrome ions - Correct Answers -only consists of one color or
wavelength
The overall calculation for the maximum permissible exposure (MPE) is based on
wavelength, duration of exposure and
the spatial distribution of light
temperature
humidity
A and B - Correct Answers -spatial distribution of light
A band pass filter: - Correct Answers -allows transmission of a narrow range of
wavelengths
Direct viewing and specular as well as diffuse reflections can cause permanent damage
from what class laser? - Correct Answers -Class IV
Visible lasers fall into what wavelength range? - Correct Answers -400nm - 760nm
