What’s the difference between 810nm and 980nm wavelengths?
Many clients ask me this question.
When using an 810 nm wavelength you have a higher absorption rate to hemoglobin and melanin in the skin whereas the 980 nm wavelength you have more absorption to water first. As a result, the 980nm is better for ablation and 810nm is better for coagulation.
But It is hard to tell the difference between the wavelengths clinically, as the absorption differences are very minor.
