Schematic of PCEF platform. The laser source is collimated and polarized by collimator and half-wave plate respectively, then the cylindrical lens is used to focus the light into a line shape perpendicular to the direction of PC-based biosensor, and the emission fluorescence light is collected by an objective lens and constructed as an image after passing through a Dichroic mirror and laser source light filter
