These images illustrate the use of a slider with the screwbarrel microscope. Note the the slider fits between the two top plates of the stage. A small pair of indentations facilitate the placement of the slider between the plates, as does the tapered front of the slider itself. The indentations of the top two plates is actually best seen in the image to the right of the next paragraph.
