The aim of the paper is to find the optim um wavelength of the laser with regard to the accuracy of measuring the wood surface roughness and to prove the relationship between the accuracy of measuring and the wavelength of the light emitted by the laser modules. The results of the measurements during which a source of red light (wavelength λ = 635nm), green light (λ = 520nm) and blue light (λ = 450nm) and beech wood surface with humidity were tested in a set of LPM laser profilometer. The results of the research showed an increase in the sensitivity of the surface roughness measurement by 60% using a blue laser beam with a λ = 450nm wavelength compared to standard red laser lamps with λ = 635nm wavelengths.
