Patent attributes
One of the principal objects of the present invention is to realize, in a small scale and at a low cost, an analyzing apparatus that analyzes and manipulates a minute sample such as DNA. The analyzing apparatus 1 incorporates an optical system for measuring a fluorescence from a sample traveling through a minute channel 24c. Specifically, a light source that generates a light for exciting a fluorescence of the sample and a light guide that guides the light from the light source to the minute channel 24c are provided, whereby the fluorescence of the sample in the minute channel 24c is well excited. In order to observe the fluorescence of the sample, a condensing optical element 26, provided on a wall surface of the minute channel 24c, for capturing the fluorescence from the sample, and a sensor section 11 are provided, whereby the fluorescence of the sample in the minute channel 24c can be well observed.
