Abstract
A light source apparatus for fluorescence photography of biomolecule sample gels is disclosed. The light source apparatus comprises a housing, a transparent plate disposed in a light transmission zone at the top of the housing, and at least one LED array disposed in the housing out of the range of the light transmission zone. The LED array irradiates obliquely to the light transmission zone for preventing the light spots from interfering in the observation. Each of LED array may comprises different colors of LEDs for different biomolecule samples.
Claims7
A light source apparatus for fluorescence photography, comprising:
- a housing having a light transmission zone located on the top thereof;
- a transparent plate disposed in said light transmission zone of said housing for supporting a biomolecule sample gel;
- at least one LED array for fluorescence photography disposed inside said housing, displaced from said light transmission zone, and positioned at a selected oblique angle to project light toward said light transmission zone and said transparent plate, wherein each of said LED array comprises a plurality of LEDs;
- and
- a controller electrically coupled to said at least one LED array for driving said LED array to said selected oblique angle wherein light spots from said LED array are prevented from interfering with said fluorescence photography.
