====== Overview  ======

The diSPIM is a flexible and easy-to-use implementation of Selective Plane Illumination Microscopy (SPIM) that allows for dual views (d) of the sample while mounted on an inverted (i) microscope.

The diSPIM has two (usually symmetric) optical paths for light sheet imaging. Two objectives are placed at right angles above a sample mounted horizontally. A light sheet is created from one objective and then imaged using the other objective. A stack of images is collected by moving the light sheet through the sample. The role of the two objectives can be exchanged to collect another stack from a perpendicular direction, and then the two datasets can be computationally merged to yield a 3D dataset with isotropic resolution.

The diSPIM "head" can be mounted on various inverted microscopes. A microscope-specific adapter bracket accepts the SPIM-MOUNT to which the SPIM assembly attaches.((Attaching the SPIM precludes use of the transmitted light optics because the brackets utilize the transmitted light pillar mounting point)) Thus far brackets exist for the following microscopes:

  * ASI RAMM frame (shown in figure below)
  * Leica DMI-6000
  * Nikon TE-300, Ti
  * Olympus IX-71/81, IX-73/83
  * Zeiss Axio-Observer


The rest of this document will concentrate on the function, alignment and operation of the diSPIM microscope. The vast majority of the instructions apply regardless of the inverted microscope frame on which the diSPIM "head" is mounted.
