Abstract
The invention relates to an optical detection system for a thermal cycling device including at least one light source, a light detection device for detecting light received from a plurality of biological samples, and a lens having first and second surfaces formed on the lens, the second surface substantially opposed to the first surface. The first surface may be configured to collimate light and the second surface may be configured to direct light into each of the plurality of biological samples.
Claims17
A detection system for a plurality of biological samples, comprising:
- at least one light source for illuminating a plurality of biological samples;
- a light detection device for detecting light received from the plurality of biological samples;
- a lens comprising first and second surfaces formed on the lens, the second surface substantially opposed to the first surface;
- and
- a heated cover comprising a surface, a lip disposed above the surface and about a perimeter of the cover, and a plurality of openings, the heated cover configured to receive the lens;
- wherein, during operation, the first surface is configured to direct light from the light source toward the plurality of biological samples and the second surface is configured to direct the light into each of the plurality of biological samples;
- wherein the second surface comprises a matrix of lenses;
- and
- wherein the openings of the heated cover are tapered from an upper edge of the opening to a lower edge of the opening.
