Summary
Diffuse reflectance spectrophotometry (DRS) is a non-invasive method recently gaining ground. The rapid technical development and need for objectification of realized examination and preservation of skin surface integrity favours non-invasive methods in the diagnostic process. Diffuse reflectance spectrophotometry is based on the interaction of optic radiation with the skin. Spectrophotemeter registers and analyses the reflected (direct and diffuse) light from the particular skin structures. This report is focused on engineering solution of spectrophotometer, device used in spectrophotometry to measure light intensity in correlation with the wave-length. The available types and components of spectrophotometers were analysed. Our experimental spectrophotometer was developed with regard to construction’s simplicity and easy setup of its technical components. Special attention was paid to selection of light-source and customers’ software for data collection specially designated for this application. This method has a wide clinical use in dermatology especially in evaluation of erythematous skin diseases and pigmentation disorders.
Key words:
diffuse reflectance spectrophotometry – difraction grating – spectrophotometer
