LASER EQUIPMENT UPDATED ACTUAL
Exam Questions and CORRECT Answers
LASER CLASSIFICATIONS - CORRECT ANSWER - Lasers are classified for safety
purposes based on their potential for causing injury to eyes and skin.
o Class 1 - Class 3R (considered eye safe)
o Class 3B - Class 4 (hazardous to eyes and skin)
NOHD (Nominal Ocular Hazard Distance) - CORRECT ANSWER - The NOHD is the
distance from the source at which the intensity becomes lower than the Maximum Permissible
Exposure (M.P.E.) on the cornea and on the skin.
The laser beam can be considered dangerous if a person is closer to the source than the NOHD
As the beam goes out, the beam divergence will increase, thus allowing less light to enter the
cornea at greater distances.
The hazard decreases the farther a person is from the laser, and the shorter the exposure time.
o SOFLAM NOHD
- 20.5 km (unaided)
- 40 - 50 km (aided)
o HLM
- 5.9 km (unaided)
- 23 - 40 km (aided)
NOTE: "Unaided" refers to the fact that no optics are being used. If optics are being used, the
NOHD may increase dramatically.
, Any personnel required to be down range during laser operations must wear proper Laser Eye
Protection.
NOTE: This does not include personnel operating the laser but refers to personnel downrange of
the aperture.
SOFLAM (Special Operations Forces Laser Acquisition Marker) - CORRECT ANSWER -
11.3 lbs. (complete laser system + battery 22.8)
Powered by 1 x BA-5590 lithium
Wavelength: 1064 nanometers
Range Mode: 200 to 19,995 meters
Designation Mode:
- 3 km (moving targets)
- 5 km (stationary targets)
10x Sighting Optics
Class 4 Laser (not eye safe)
SOFLAM CONTROLS - CORRECT ANSWER - Mode Switch
o OFF (turns the SOFLAM off)
o RANGE (rangefinder mode only)
o MARK (laser designating function w/ rangefinding)
o O/R (same as MARK...will allow the SOFLAM to override a HOT alert and continue to
operate)
PRF Code Pushbuttons
o First digit understood to be "1"
o 3 pushbuttons set the last 3 digits (numbers 0-9)
o PRF Code Range (1111-1788)
