MICRO LUMINESCENCE ANALYZER

PROBLEM TO BE SOLVED: To provide a micro luminescence analyzer simple in construction and low in price for easily finding the luminescence intensity of a substance and an average amount of spectrum wavelengths. SOLUTION: By a data processing part 9 of this analyzer, a look-up table is referred to, with the table formed so as to mutually parallelize the value of a ratio between a sensitivity value f1(λ), where a first filter 16 is inserted therein, and a sensitivity value f2(λ), where a second filter 17 is inserted therein, with the size of a wavelength λ uniquely derived from the value of the ratio of the sensitivity value. The value of a ratio between a first detection value D1(λ) detected through the first filter and a second detection value D2(λ) detected through the second filter is compared with the value of the ratio between the sensitivity values. From the value of a ratio between together conforming sensitivity values, a corresponding wavelength λ is derived as a barycentric wavelength while the total amount of luminescence is calculated from relations between the sensitivity values of the respective filters and the first and second detection values D1(λ) and D2(λ).
