Vectra Genisys Laser System Light Source Diodes - All therapeutic light sources available today are generated by a semi-conductor diode.
It is an option when the condition is very close to the surface. Typical Light Collimation, Wavelength and Power affect depth of penetration and are all important technical criteria for evaluating Laser Light Therapy. The selection of spot size, wavelength and power needs to be based upon the type and depth of conditions being treated.
Collimation relates to the spot size or spread of the light source. The more focused the beam, the deeper the light source can penetrate before scattering in the tissues. When comparing the light sources at the same power output, a focused, laser light beam will penetrate further into the target tissue than non- collimated, non-focused light, such as SLD's and LED's.
Wavelength also affects the depth of penetration. The longer the wavelength, the deeper the penetration. Infrared light will penetrate deeper than red light.
Power is the amount of light energy delivered per unit time. Higher power increases effective depth of penetration and takes less time to deliver the same amount of energy. A high-powered SLD or LED light source, even at longer wavelengths, may not deliver a therapeutic dose to tissues of moderate or deeper depth. Does Low Level Laser Therapy meet the needs of my patient's condition? It offers the clinician the most comprehensive offering of modalities 6 in one complete therapy system.
