Abstract: A microscopic image capturing apparatus and method are provided. First, the entire area of a slide glass on a stage is divided into field size sections (low-magnification sections) of a low-powered objective lens. The stage is transferred perpendicular to an optical axis, and image information is sequentially obtained for each low-magnification section. Each low-magnification section is divided into high-magnification size sections (high-magnification sections), and a high-magnification image is captured using a high-powered objective lens only in high-magnification sections corresponding to a sample. A high-magnification image is generated by correctly maintaining the relative position between the obtained image information and an area corresponding to high-magnification sections which are not captured, and high-magnification composite image information of the sample is generated.

Abstract: A system for the optical analysis of a sample. An illumination source illuminates the sample, exciting fluorescence.

Both the objective lens and the imaging lens are positioned on a mount that allows an alternative objective or imaging lens to be positioned to collect or image the emitted light. Any objective lens/imaging lens pair is optically symmetrical, greatly reducing the optically degrading effects.
