In Edit>Options>Input/Output, enable "Save TIFF and raw in Intel byte order", then save the images using File>Save As>Raw. The images will be saved as raw in their current format (8-bit, 16-bit unsigned, 32-bit float or RGB).

With JavaScript or a plugin, use

 imp = IJ.getImage();
 Prefs.intelByteOrder = true;
 IJ.saveAs(imp, "Raw Data", path);
