Method for working in a specimen and a stage for the method

Abstract

A method for working in a specimen includes the steps of (a) putting the specimen on a stage; (b) irradiating radiation to the specimen for excitation; (c) recording detected characteristics of the excited specimen by the radiation; (d) displaying the recorded characteristics on the stage; (e) storing the recorded characteristics of the excited specimen; (f) maintaining display of the stored characteristics on the stage; and (g) working on the specimen on the stage over the displayed characteristics. An operator may easily access to the specimen with a scalpel or a knife since the detected characteristics are displayed on the stage after the detection of the characteristics. Even if the detection requires harmful radiation such as ultraviolet light, the operator may work in the specimen after turning off such harmful radiation. Therefore, the operator does not have to wear any protection against the harmful radiation so as to work in the specimen more easily and efficiently. Further, according to the present invention, a very delicate specimen, such as deoxyribonucleic acid, may be analyzed with less deterioration of the specimen since the excitation radiation is not necessary during the work in the specimen. In fact, a momentary excitation radiation may be sufficient to display the necessary characteristics on the stage.
