Avlee 650 Avlee 650 uses the patented laser diffraction method. Our solution allows you to acquire a “fingerprint” of the microorganisms studied by diffracting light on colonies of microorganisms. Identification technology is nothing more than the recognition of colonies of microorganisms that exhibit specific optical (absorption and refraction coefficient) and morphological properties (profile, edge shape). These properties lead to the modulation of both the amplitude and phase of the light beams falling on the colonies. As a result of this transformation, the waves are diffracted on colonies that act as a lens and thus become the information carrier. More about our technology.
