ABSTRACT:
A modular, micro-scale, optical array and biodetection device for quantifying fluorescence intensities of a plurality of substantially separated, and dimensionally uniform elements of a bioarray that are located at known positions on a plain support includes a light guide that directs bioarray illumination light from a respective light source to opposing sides of the plain support. An optical module collecting light individually from the bioarray elements includes an optical member, a filter, and a sensor, such as a CCD chip. The optical member collects and transfers emitted light from the bioarray elements via the filter to the sensor. The filter transfers light from the elements having a predefined wavelength spectrum and blocks light outside the predefined wavelength spectrum. The sensor receives transferred light from the elements and produces a signal corresponding to respective elements of the bioarray.
