University of Washington bioengineering student Spencer Boyar developed this device to capture images of zooplankton from different angles. It uses one camera and two mirrors to capture images from five angles. A motorized syringe draws the sample into the imaging chamber, the image is recorded, and the sample is automatically pushed out. Parts are made from ABS (acrylonitrile butadiene styrene) plastic; they snap together and can be inexpensively produced on a computer numerical control (CNC) mill.
