SCANNING SYSTEM AND METHOD FOR SCANNING A PLURALITY OF SAMPLES

摘要

A system for detecting fluorescence emitted from a plurality of samples in a sample tray is provided. The system generally includes a plurality of lenses (12) positioned in a linear arrangement, a linear actuator configured to translate the plurality of lenses, an excitation light source (16), an excitation light direction mechanism (18) for directing the excitation light to a single lens of the plurality of lenses at a time so that a single sample holder aligned with the lens is illuminated at a time, and an optical detection system (20) for analyzing light from the sample holders. In certain embodiments, the optical detection system includes a light dispersing element (80), and a lens element (82) to direct the light onto a light detection device (90). A method of scanning a sample tray having a plurality of samples positioned in sample holders to detect fluorescence is also provided.
