The reason for this errata is a typing error in the photobiomodulation probe specifications, there was an extra 0 (zero) in the wavelength, where you read 6060-nm, it should be 660-nm (page 2, paragraph 5, line 4). We rewrote the sentence with the corrected wavelength specifications for replacement.

Original sentence:

The probe contains 34 × 6060-nm LED with the following specifications: 6060-nm central wavelength; spectral width of 20 nm at 50% intensity, average power of 10 mW, active area of 0.2 cm2; power density (irradiance) of 51 mW/cm2; and beam divergence of 20° half angle associated with 35 × 850-nm LED with the following specifications, 850-nm wavelength; spectral width of 45 nm at 50% intensity, average power of 30 mW, active area of 0.2 cm2; power density (irradiance) of 150 mW/cm2; and beam divergence of 22° half angle leading to 1390 mW of total power, an outer diameter probe of 70 mm, 63 mm of diameter of active area, and an average power density of 44.6 mW/cm2.

Corrected sentence:

The probe contains the following specifications: 34 × 660-nm central wavelength LED, with spectral width of 20 nm at 50% intensity, average power of 10 mW, active area of 0.2 cm2; power density (irradiance) of 51 mW/cm2; and beam divergence of 20° half angle; associated with 35 × 850-nm wavelength LED, with spectral width of 45 nm at 50% intensity, average power of 30 mW, active area of 0.2 cm2; power density (irradiance) of 150 mW/cm2; and beam divergence of 22° half angle leading to 1390 mW of total power, an outer diameter probe of 70 mm, 63 mm of diameter of active area, and an average power density of 44.6 mW/cm2.
