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.
Claims36
An optical detection system for a thermal cycling device, comprising:
- 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,
- wherein the first surface is configured to collimate light and the second surface is configured to direct light into each of the plurality of biological samples.
A lens for an optical detection system of a thermal cycling device, the lens comprising:
- a collimating surface;
- and
- a matrix surface substantially opposed to the first lens surface, the matrix surface comprising a plurality of focusing lens segments,
- wherein the collimating surface is configured to collimate light from a light source, and further wherein the plurality of focusing lens segments are configured to direct light into a plurality of biological samples.
An optical detection system for a thermal cycling device, comprising:
- at least one light source;
- a light detection device for detecting light received from a plurality of biological samples;
- a lens body having a first surface formed into the lens body and a second surface formed into the other side of the body;
- a sample block assembly configured to receive a sample well tray, the sample well tray configured to contain the plurality of biological samples,
- wherein the sample block assembly includes a heated cover configured to receive the lens, and
- wherein the first surface is configured to collimate light and the second surface comprises a lens matrix comprising a plurality of focusing lens portions configured to direct light into each of the plurality of biological samples.
A method of testing a plurality of biological samples, the method comprising:
- providing light from at least one light source;
- providing a light detection device for detecting light received from the plurality of biological samples;
- providing a lens having a collimating lens portion formed on a first surface of the lens and a matrix of focusing lens portions formed on a second surface of the lens, the first surface substantially opposed to the second surface,
- wherein light passes through the collimating and focusing lens portions into the plurality of biological samples and is detected by the detection device.
