Photobiomodulation (PBM Therapy) Safety
Some THOR products are class 3B lasers (others are LED's).
Class 3B lasers are potentially hazardous to the eye.
Never stare into the beam or direct the beam into the eyes of others.
THOR lasers are not collomated, they are divergent, this means that the beam expands and becomes less hazardous the futher away you get from the treatment prob aperture.
The Nominal Ocular Hazard Distance (NOHD) for our 810nm 200mW lasers has been calculated to be 1.15 meters.
NOHD is the distance at which the laser output is safe to view without safety spectacles.
i.e. below the Maximum Permissible Exposure (MPE).
All people present in the treatment area should wear appropriate laser safety eye wear.
What is appropriate ?
Laser safety eyewear should match the laser wavelength and have sufficient optical density at that wavelength to protect the eye.
THOR offer laser safety eyewear for sale that matches the laser wavelength / powers offered and meet ISO recomendations.
