-In general the diSPIM approach is ideal for cells or small groups of cells (e.g. c. elegans embryos).  For thicker samples (e.g. Drosophila embryos) where the light sheet cannot penetrate across the sample the Zeiss/OpenSPIM approach has the advantage that all sides of the sample can be directly seen.  For sub-diffraction resolution on thin samples lattice light sheet gives better resolution (though much of the advantage can be gained simply by using the lattice light sheet objectives on the diSPIM).  The LaVision BioTec system is optimized for large fixed samples, though such samples can also be imaged on the diSPIM with suitable objectives.+In general the diSPIM approach is ideal for cells or small groups of cells (e.g. c. elegans embryos).  For thicker samples (e.g. Drosophila embryos) where the light sheet cannot penetrate across the sample the Zeiss/OpenSPIM approach has the advantage that all sides of the sample can be directly seen via rotating the sample.  For sub-diffraction resolution on thin samples lattice light sheet gives better resolution (though much of the advantage can be gained simply by using the lattice light sheet objectives on the diSPIM).  The LaVision BioTec system is optimized for large fixed samples, though such samples can also be imaged on the diSPIM with an appropriate [[http://www.asiimaging.com/index.php/cleared-tissue-objective|objective for cleared tissue]].
  
 Instruments which rely on a single fixed view lead to relatively poor axial resolution and poor imaging of scattering samples. Instruments which rely on a single fixed view lead to relatively poor axial resolution and poor imaging of scattering samples.
