How deep into the tissue can the ML830 Laser penetrate?
The depth of penetration of laser light depends on the light’s wavelength and power output. The ML830 is a GaAlA Laser that has wavelength of 830 nm with a power output of 90 mw. At this wavelength and power the ML830 Laser has a penetration of approximately 5 cm with a 3 cm lateral spread. If you are working in direct contact with the skin and press the probe against the skin, the greatest active depth will be achieved.
