BIOLASER 1 and BIOLASER 2 - comparison
BIOLASER 1 and BIOLASER 2 stimulation lasers are both constructed
according to identical design assumptions. Technically, the only element
which differs in the two devices is the active element, i.e. the laser
diode. BIOLASER 1 emits infrared radiation at wavelength 790nm or 808 nm, while
BIOLASER 2 emits red light at wavelength 635nm.
Light wavelength has a huge therapeutical meaning. Infrared easily
penetrates the skin, while red light is better absorbed by the skin. The
graph below displays the absorption of the laser light by biological
tissue:
BIOLASER 2 emits red light, which less easily
penetrates the skin, therefore the device is suitable rather for
surface treatment - the whole energy is absorbed by outer
layers of the skin. The infrared laser BIOLASER 1 emits
radiation which penetrates the skin more easily, therefore
performs better in treating inflammations, aches of bones
and joints, etc. Both devices have similar applications,
but there is a shift of efficiency maximum - red is
approx. 30% more efficient when treating surface, infrared
is approx. 30% more efficient in treating the deeper layers.
