An optical detector (5) for equipment for measuring a substance in a liquid, haemoglobin in whole blood for exemple, present in a transparent receptacle (6), comprises a body (7, 8) having a seat (11, 11 min , 11 sec ) for the receptacle (6), a source (22) of light radiation and an optical sensor (27) aligned transversally with respect to the seat. The surfaces of the seat (11, 11 min , 11 sec ) are reflective. Thanks to the reflexive surfaces of the seat (11, 11 min , 11 sec ), the undesirable scattering effect of light in the liquid is considerably reduced and the detector (5) is capable of delivering a signal enabling an accurate determination of the concentration of the substance to be measured. <IMAGE> |
