Bright-field illumination

Michael Redd from the Cell Imaging Core Facility at the University of Utah put together an Arduino-based solution to get proper bright-field illumination in an OpenSPIM setup: Brightfield.

Stepper Motor Upgrade

If you would like to swap out one of the Picard stepper motors you can do so with a bit of effort.

Instructions about how to go about this for a Thorlabs DRV001 connected via a Thorlabs BSC201 controller on a 64bit OpenSPIM setup are detailed below (by Jerome Boulanger and Ben Sutcliffe):

  1. Download the micro-manager source code as instructed here (
  2. Instal all the relevant programs for building micro-manager as instructed here (
  3. Setup up Visual C++ 2010 Express as here (
  4. Instal the 64bit APT software from Thorlabs (
  5. Download and unzip the APTx64 form here (
  6. Then build the ThorlabsAPTStage Device Adapter in 64bit on a 64bit Windows 7 machine, using the 'APT.lib' downloaded in point 5.
  7. Rename the resulting .dll file to 'mmgr_dal_ThorlabAPTStage.dll' then place it into the folder along with the 'APT.dll' downloaded in point 5.
  8. The OpenSPIM Fiji/MM bundle can then restarted and a ThorlabAPTStage could be configured as described for a 32bit system here (

More details to follow about incorporating this into the SPIMAcquisition plugin.

OpenSPIM for large samples

Field of view

The original OpenSPIM uses a 2X expander to enlarge the laser beam to 2 mm. For larger samples a larger field of view can be preferable. This means that you will need a larger beam to create a taller light sheet. Change the second beam expander lens to f=75 mm or 100 mm and increase the distance between lenses accordingly.


Immersion objectives with long working distance are hard to find. However, at low NA and moderate magnification, a dry objective will also work; the higher NA, the more spherical aberrations will be present. Keep in mind that when using a dry objective in immersion, the WD will increase (approximately by a factor equal to the RI of the new medium, eg. 17 mm in air will increase to 22.6 mm in water).

Example parts list

The table below lists the parts used by the OpenSPIM for brains setup built by Monika Pawłowska (Nencki Institute of Experimental Biology, Warsaw).
