1.2.1 LASER SAFETY moorLDI2-VR AND moorLDI2-HR
The laser light source in these moorLDI2 scanners is a Helium-Neon visible red gas laser (633nm).
The maximum accessible power is 2.5mW for instruments using the gas laser.
For the VR type the beam divergence is approximately 1.4 milliradians, with a beam diameter (1/e
2
points) at 50cm from the laser aperture of approximately 1.2mm.
The ocular hazard distance is 25m.
For the HR type the laser beam is focussed to a spot size of approximately 0.1mm at 25cm from the
laser aperture.
The ocular hazard distance is 25m.
The level of laser radiation is below the maximum permissible exposure (MPE) for skin but it
presents a significant hazard if the eye is exposed to the full power of the laser beam, either by direct
viewing along the beam, or by specular reflection.
The blink reflex of the eye provides a measure of protection, however direct viewing of the beam
should be avoided.
1.2.1.1 Training
Only persons who have received training to an appropriate level should be placed in control of the
moorLDI2. The training, which may be given by the manufacturer or supplier of the system, the
Laser Safety Officer, or by an approved external organization, should include, but is not limited to:
a. Familiarisation with system operating procedures.
b. The proper use of hazard control procedures and warning signs.
c. The need for personal protection.
d. Accident reporting procedures.
e. Bio-effects of the laser on the eye and the skin.
1.2.1.2 Unauthorised Access
When the moorLDI2 is not in use by authorised personnel, measures should be taken to prevent
unauthorised use. This will normally be achieved by storage in a locked area.
