It's called a prismatic compass because of the right-angled prism that folds over the compass. When the eye is brought close to the prism the readings can be taken while sighting the point of observation. The prism's height can be adjusted for sharper readings off the scale on the compass card. The glass above the compass has a scale that can be adjusted with a screw on the side. The cover has a round sighting glass window with a dividing line. The prismatic compass was an indispensable instrument for officers in the British Army.
