PURPOSE:To automatically perform the diagnosis of cancer, by irradiating a specimen with polarized exciting light to generate fluorescence and electrically processing the polarization degree of said fluorescence. CONSTITUTION:A specimen 5 to be subjected to the judgement of cancer is placed in a diagnostic apparatus and at first irradiated with an observation and transmission illumination system, in such a state that a shutter 3 is opened and a shutter 9 is closed, and the focus adjustment of an objective lens is performed while the specimen 5 is observed by an eyepiece 15 or the part to be measured in the specimen 5 is determined. Next, the shutter 3 is closed while the shutter 9 is opened to perform the illumination by a projected fluorescent polarization and measuring illumination system. By this method, the specimen 5 illuminated by polarized exciting light emits fluorescence and two polarized components crossing at right angles of said fluorescence are received by light receiving elements 17a, 17b through a Wollaston prism 16 and the aforementioned polarization degree P is operated through amplifiers 18a, 18b and an operation processing circuit 19 to judge cancer and the result thereof is displayed by a display apparatus 20. |
