Abstract: In one embodiment, a flow cytometer is disclosed having a compact light detection module. The compact light detection module includes an image array with 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. 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. A radius of curvature of each of the plurality of micro-mirrors images the fiber aperture onto the odd filters and collimates the light beam on the even filters.
