Capillus laser therapy devices use only medical grade laser diodes as a light source. What does this mean? You get the right amount of light energy exactly where you need it. Capillus uses lasers because the output penetrates deeper, better and is clinically proven to be therapeutic for their specific purpose.
Laser light does not spread as much as LEDs over the same distance, which allows lasers to penetrate tissue to a deeper level with higher concentration. For photobiomodulation therapy, the farther the light is from the target, the less intense and less effective the treatment will be.
For light therapy to be effective, it needs to reach the cells that respond well to photobiomodulation therapy.
LASER stands for Light Amplification by Stimulation of Emitted Radiation. This simply means that a source of light is amplified within a gain medium and emitted in a specific way. LASER produces a very intense beam of light which has the following properties:
- Monochromatic (meaning it consists of one wavelength)
- Coherent (meaning all parts are in phase)
- Collimated (meaning all parts travel in one and same direction)
LED stands for Light-emitting Diode. And it’s pretty much just that. A diode that emits light when electricity passes through it. Often in pretty colors.
LED light can produce collimated light (with a focusing lens) but not coherent light thus they do not concentrate all their power in a coherent beam. Laser diodes by definition produce effective collimated and coherent light output.
