FIELD: physics.
SUBSTANCE: apparatus has a light source for generating a plurality of light beams, each of the plurality of light beams having a wavelength range different from the others, as well as a light funnel for directing the plurality of light beams to the analysis region, an aperture for directing the plurality of light beams from the analysis region to the lens. The lens is configured to collect light beams from the analysis region. The apparatus also has a detector which has a plurality of light-sensitive devices, each configured to detect a light beam and generate an output signal indicating intensity of the detected light, and a processor for determining blood characteristics as a function of each generated output signal.
EFFECT: invention makes multiple checks painless and increases intensity of the determined light.
