Compact detection module for flow cytometers

A flow cytometer comprising:

• a light detection module including
• a first image array having
• a transparent block,
• a plurality of micro-mirrors in a row coupled to a first side of the transparent block, and
• a plurality of filters in a row coupled to a second side of the transparent block opposite the first side,
• wherein each of the plurality of filters reflects light to one of the plurality of micro-mirrors and passes light of a differing wavelength range and each of the plurality of micro-mirrors reflects light to one of the plurality of filters, such that incident light into the image array zigzags back and forth between consecutive filters of the plurality of filters and consecutive micro-mirrors of the plurality of micro-mirrors,
• wherein a radius of curvature of each of the plurality of micro-mirrors directs light onto even filters and reimages light onto odd filters of the plurality of filters along the row;
• and;
• a first plurality of detector channels in a row forming a first detector chain adjacent the first image array, the first plurality of detector channels respectively in light communication with the plurality of filters of the first image array, wherein each detector channel includes a focusing lens, and a photo detector.
