Das Zielfernrohr muss gegenüber dem Lauf der Schusswaffe derart justiert sein, dass bei jedem Schuss die gleiche Ausrichtung gewährleistet ist. Diese mechanische Vorrichtung zur Befestigung des Zielfernrohrs an der Waffe wird Montage genannt.

Seit der ersten Mondlandung 1969 ist eine äußerst exakte Entfernungsbestimmung möglich. Von der Besatzung der Apollo 11 wurde damals eine Anordnung von Retroreflektoren, das sogenannte lunar laser ranging retroreflector array, auf der Mondoberfläche im Mare Tranquillitatis aufgestellt (siehe Bild). Dadurch ist es möglich, die Entfernung des Mondes auf wenige Zentimeter genau zu bestimmen. Dazu wird von der Erdoberfläche ein Laserstrahl ausgesandt (siehe Bild), der genau auf den Reflektor auf der Mondoberfläche gerichtet ist. Durch dessen Struktur wird der Laserstrahl wieder exakt zum Sender zurückgeworfen. Im Normalfall kommen vom ausgesandten Signal nur wenige Photonen, manchmal sogar nur ein einziges, zurück, die detektiert werden können. Aus der Zeit, die zwischen Aussendung und der Rückkehr des reflektierten Signals vergeht, lässt sich dann die Entfernung genau bestimmen.[3]

Bei Großformatkameras wird in der Filmebene eine Mattscheibe befestigt und die Entfernung durch den Schärfeeindruck des vom Objektiv auf der Mattscheibe projizierten Bildes bestimmt. Der Wert kann auf einer kalibrierten Skala im Laufboden abgelesen werden. Bei einigen Modellen muss die Mattscheibe nach der Einstellung für die Aufnahme weggeklappt oder verschoben werden. Andere lassen sich anheben und die Filmkassette wird dann einfach zwischen Mattscheibe und Kamera geschoben.
