Claim:
1. A system for measuring the concentration of hemoglobin in whole blood, the system comprising: a light radiating member comprising at least one light source, the light source emitting an incident light having a first wavelength of 546 nm, 570 nm or 584 nm and a second wavelength of 800 nm or 850 nm; a diffuser distributing the incident light emitted from the light radiating member; a guide for the light source guiding the incident light to the diffuser; a cuvette accommodating member configured to accommodate a cuvette for whole blood; a guide for the incident light guiding the light incident upon the diffuser to a measuring zone of the cuvette comprising the whole blood; a detector detecting a first absorbance of the incident light having the first wavelength which has passed through the whole blood and a second absorbance of the incident light having the second wavelength which has passed through the whole blood; a guide for the detector guiding the incident light that has passed through the measuring zone to the detector; a processer determining the amount of hemoglobin in the whole blood using the first and the second absorbance detected by the detector; and a controller regulating the incident light such that the incident light of the first wave length and the second wave length are radiated in a sequential order, wherein: the guide for the light source has an inner diameter which is identical to or larger than that of the guide for the incident light; the guide for the incident light has an inner diameter which is identical to or smaller than the size of the measuring zone; and the guide for the detector has an inner diameter which is identical to or smaller than that of the guide for the incident light.
