A confocal fluorescence microscope of the present invention consists of: a light source unit broadly comprising one or more short wavelength laser beams; a lens unit which converts parallel light, emitted from a light source, into linear light having an appropriate size; a multi-color mirror which reflects the light source and enables fluorescence to transmit so as to separate the light source and the fluorescence; a scan mirror which radiates the light source over a wide area and scatters the fluorescence over a large-area camera; a microscope unit which radiates the incident light source to a target object, collects the fluorescence emitted from the target, and outputs the collected fluorescence; and a detecting unit which removes the background of the outputted fluorescent signal and observes the outputted fluorescent signal.

Confocal fluorescence microscope

Disclosed is a surface plasmon optic device that has a periodic array of apertures in a dielectric substrate and a metal film formed on the dielectric substrate and emits light from metal-air interface. The surface plasmon optic device includes a surface plasmon generating apparatus, a surface plasmon detecting apparatus, a surface plasmon controlling apparatus, an etching apparatus, etc. if a metal diffraction grating is disposed on the metal film having a well-defined interface, propagation of the surface plasmon can be efficiently reflected, divided and controlled. Further, radiating surface plasmon having a half period of a lattice constant formed at air-metal () can be preserved at a distance of at least a few micron.
