High speed, wide area microscopic scanning or laser positioning is accomplished with an inertia-less deflector (for example an acousto-optic or electro-optic deflector) combined with a high speed wide area microscopic scanning mechanism or laser positioner mechanism that has inertia, the motion of the inertia-less deflector specially controlled to enable a focused spot to stabilize, for example to stop and dwell or be quickly aimed. It leads to improved data acquisition from extremely small objects and higher speed operation. In the case of fluorescence reading of micro-array elements, dwelling of fluorophore-exciting radiation in a spot that is relatively large enables obtaining the most fluorescent photons per array element, per unit time, a winning criterion for reducing fluorophore saturation effects. The same inertia-less deflector performs stop and dwell scanning, edge detection and raster scans. Automated mechanism for changing laser spot size enables selection of spot size optimal for the action being performed.
