- overlay UV/V and VIS (confocal systems with separate UV/V laser coupling)
- purpose: check the coupling precision of the UV/V laser
- requirements: 0.2/0.5µm fluorescent beads sample
- work flow: open pinhole(s), use high resolution apochromatic lens (NA 1.2 or above), acquire two images (UV/V plus VIS channel) with good sampling (pixel size ~100nm)
