Abstract: An element for optical measurement system including a first crown extending circumferentially around an axis and including at least one first optical lens, and a second crown located radially outside of the first crown and surrounding the first crown and including at least one second optical lens where at least one first lens is aligned with at least one second lens, the first and second crowns are made of the same material so as to form a unitary element.
Abstract: A measuring cuvette for counting and/or characterizing cells, the measuring cuvette including a base and a transparent lateral enclosure extending from the base so as to form with the latter an optical measurement chamber; the base having a through-orifice with a diameter of 30 to 100 ?m for cells to pass through, characterized in that the base and the transparent lateral enclosure form a one-piece cuvette suitable both for impedance measurement and for optical measurement. Also, a system for characterizing cells, which includes the measuring cuvette.
