Abstract
PURPOSE:To eliminate the need for rotary sector or the like and then increase both the reliability and the lifetime of the device, by installing at least two units of detection elements having different spectral sensitivities to each other within the radiation energy condenser system of the subject to be measured. CONSTITUTION:The measurement light L sent from the subject 1 to be measured is condensed by the optical system such as the condenser lens 2 or the like and then is incident on the detection elements D1 and D2 having different spectral sensitivities (such as lambda1 and lambda2) and provided within the optical system to be received there. The detection signals of the energy corresponding to lambda1 and lambda2 sent from the subject 1 and detected by the elements D1 and D2 are amplified through the amplifiers 41 and 42 each and the processed by the arithmetic circuit 8 to be delivered through the terminal 7. It is preferable to turn at least the above-mentioned two detection elements into the single element and to provide the light diffusing plate at the front of at least the two detection elements each.
