A condensing-type portable fluorescence detection system which detects antigens using fluorescence includes: a light source generating light to excite a fluorescent substance; a first filter selecting a proper wavelength range from the light generated from the light source; a spherical mirror including two hemispherical mirrors having different curvature radiuses and connected to each other, and condensing the light excited and emitted from the light source; a second filter selecting a proper wavelength range of the light condensed by the spherical mirror; and a photodetector detecting fluorescence from the light condensed by the spherical mirror and passing through the second filter.

대표청구항 ▼

1. A condensing-type portable fluorescence detection system which detects antigens using fluorescence, comprising: a light source to emit a light;a first filter to receive the light and selectively pass a first wavelength range of light, wherein the first wavelength range of light is to cause a fluorescent substance to emit a fluorescent light;a spherical mirror to contain the fluorescent substance on a plane passing through the spherical mirror, the spherical mirror comprising: a dome reflector having a first radius of curvature, anda hemispherical reflector having a second radius of curvature different from the first radius of curvature,wherein the dome reflector and the hemispherical reflector connected to each other in the plane, andwherein the radius of curvature of the dome reflector and the radius of curvature of the hemispherical reflector are configured to cause a path of the fluorescent light to travel a plurality of generally trapezoidal-shaped optical paths to condense the fluorescent light toward a light exit of the spherical mirror;a second filter, located proximate the light exit of the spherical mirror, to receive the fluorescent light and selectively pass a second wavelength range of light; anda photodetector, located proximate to the second filter, to detect the second wavelength range of light to identify the fluorescent substance,wherein the spherical mirror comprises a light entrance to admit the first wavelength range of light into the spherical mirror, andwherein the light exit is formed in the dome reflector. 2. The fluorescence detection system of claim 1, wherein the light source comprises an LED. 3. The fluorescence detection system of claim 1, wherein the first filter and the second filter each comprises: a plurality of different selectable filter elements, wherein a selectable filter element is selected to match a characteristic of the fluorescent substance. 4. The fluorescence detection system of claim 1, wherein the first filter and the second filter each comprises: a filter rotating unit containing selectable filter elements, wherein a selectable filter element is selected by rotating the filter rotating unit. 5. The condensing-type portable fluorescence detection system of claim 1, wherein the hemispherical reflector condenses a portion of the fluorescent light that is reflected below the plane toward the light exit and the dome reflector reflects fluorescent light toward the hemispherical reflector. 6. The fluorescence detection system of claim 5, wherein the spherical mirror is formed of at least one of plastic, metal, glass, or polymer. 7. The fluorescence detection system of claim 6, wherein the spherical mirror has an inner surface coated with at least one of aluminum (Al), gold (Au), or silver (Ag) to increase reflectance. 8. The fluorescence detection system of claim 5, wherein the spherical mirror is formed of plastic and has an inner surface coated with silver (Ag). 9. The fluorescence detection system of claim 1, wherein the light source and the first filter are integrated and installed at a light entrance of the spherical mirror, and the second filter and the photodetector are integrated and installed at the light exit of the spherical minor. 10. The condensing-type portable fluorescence detection system of claim 5, wherein the reflector is a parabolic reflector.
