| 摘要 |
<p>The invention concerns an optical measuring head (10) of a chemical or biological reaction analyser comprising a first colorimetric analysis detector (12) controlled by a light source (20) associated with an optical fibre (28) transmitting a light beam to one of the reaction analysis plate (18) sides. A light detector device (37) is arranged on the opposite side for sensing the emergency light beam from the well (16). The light source (20) and the reaction analysis plate (18) are fixed, while the measuring head (10) is mounted on a U-shaped mobile support (19) enclosing the plate analysis (18) opposite parallel surfaces, and capable of being moved by a driving mechanism (48) opposite a predetermined well (16). The optical fibre (28) has one end attached to the fixed light source (20), and one opposite end arranged in a housing (30) of the mobile support (19).</p> |
