The new microscope, called Multi-View SPIM (MuVi-SPIM) shines a thin sheet of light on the embryo, illuminating one layer of the embryo at a time to prevent light damage.
We didn't get time (nor did the miserable London weather permit us) to try the Muvi HD out in the full gamut of situations that we'd like, but from what we did manage, we were generally pleased.
