Images of target grids captured with Olympus 40 × oil immersion objective lens fitted in (a) LLM50, (b) LLM36 and (c) LV200 system. The images are layered with virtual grids (green lines). Since the EMCCD in the LV200 is 1024 × 1024 pixels, the actual image area is ~2.6 times larger than (a) and (b).
