In this paper, to find the quantitative errors of aqueous glucose induced by the temperature change at every wave point ranging from 1200nm to 1700nm, the calibration curve is calculated and shown. During the measurement the temperature varies from 30° to 40°, at a 2° interval, and aqueous glucose concentration ranges from 100mg/dL to 500mg/dL, at a interval of 100mg/dL. The absorption of aqueous glucose decreases with the increasing of temperature, also the absorbance decreases. In addition, only 1° change in the temperature induces about -7�?10-3 and -4�?10-3 errors in the absorbance of the aqueous glucose at the wavelength of 1550nm, 1610nm respectively. So the examined result should be correct according to the data read from the calibration curve if the temperatures of modeling and measuring are not uniform. Using this method, the error caused by the temperature change can be reduced even eliminated.
