From: Efficiency, error and yield in light-directed maskless synthesis of DNA microarrays
Calculated aerial views of intensity on the synthetic surface from a 3 × 3 array of micromirrors. A. Only central mirror ON. B. Only central mirror OFF. C. All mirrors ON. D shows a logarithmic plot of the light intensity reaching a central horizontal line through A (dash), B (solid) and C (dot-dash). In all cases the edges of the illuminated synthesis pixels lack sharpness, and particularly for the all ON pattern, the gaps between pixels are receive substantial intensity, about 50% of maximum pixel intensity.
