Erythema and melanin indices are indicators quantifying intensity of skin erythema and pigmentation. With traditional colorimeters erythema measurement is often affected by melanin and vice versa. These issues have been solved in the fully portable and pocket sized Delfin SkinColorCatch.

The device also shows RGB, CIE L*a*b* and L*c*h* color coordinates and calculates automatically the ITA degree, which classifies the skin tone. The SkinColorCatch may be used either as a stand-alone device or measurement data may be collected wirelessly to the DMC software where more color parameters are displayed. The DMC software allows users to set up individual projects and plot and print the results or export measurement data to other programs for editing.

SkinColorCatch Instrumentation and Measurement Principle

White LEDs corresponding to daylight are arranged circularly inside the measurement chamber of the SkinColorCatch. When the SkinColorCatch is gently placed on the skin, the LEDs illuminate the skin in the angle of 45 degrees to minimize gloss. The light reflecting back from the skin is detected with an RGB color sensor. The measured RGB and L*a*b* readings are corrected using a reference color matrix measured with a spectrophotometer. The measurement is not affected by ambient lightning conditions and the optical orifice of the SkinColorCatch is designed to minimize possible blanching effects caused by the contact pressure against the skin.
