Abstract:
1. An optical detection system, comprising: a light source configured to illuminate at least one of a plurality of biological samples; a light detection device configured to detect luminescence from at least one of a plurality of biological samples; a single-piece lens having first and second surfaces formed on the lens, the second surface facing a direction opposite to that of the first surface, the first surface collimating light from the light source and the second surface comprising a plurality of diffractive elements configured to receive transmitted light from the first surface and produce a plurality of focal spots from light received from a common light source, at least one of the diffractive elements comprising at least one of a diffraction grating, a surface-relief diffractive lens, or a holographic optical element; and a sample block assembly configured to receive a sample well tray, the sample well tray being configured to contain the plurality of biological samples, the sample block assembly including a heated cover configured to receive the lens.
