Die optische Abstandsmessung bietet viele verschiedene Verfahren, die im Bereich bis ein Mikrometer und sogar deutlich darunter praktikabel sind. Das Phasenschiebeverfahren ermöglicht Abstandsmessungen bis zu einem Hundertstel der Lichtwellenlänge und wird in Interferometern oder Weißlichtinterferometern eingesetzt.

Wegen der erforderlichen geometrisch genauen Abbildung werden ausschließlich Apochromate eingesetzt. Die Vergrößerung beträgt zwischen 20- und 60-fach, um die erforderliche Zielgenauigkeit zu erreichen.

Die direkte Messung ist die gebräuchlichste Methode der Entfernungsmessung im Alltag. Man vergleicht die zu messende Entfernung mit einem Vielfachen des Längennormals. Das erfolgt üblicherweise nicht mit einem Replikat des rechts dargestellten Urmeters, sondern mit einem preiswerten und handlichen Gliedermaßstab, Maßband oder Lineal. Mit diesen Messmitteln können auch längere Strecken bestimmt werden, indem man die Maßstäbe mehrfach hintereinander setzt. Dadurch vergrößert sich natürlich auch der Messfehler. Für sehr kleine Längen im Alltag von 0,1 Millimeter bis 200 Millimeter verwendet man mechanische Präzisionsmessinstrumente wie Messschieber oder Mikrometerschrauben. An unzugänglichen Stellen z. B. zwischen Maschinenteilen können auch deformierbare Wachsstreifen, sogenannte Plastigauges eingesetzt werden.

„Standard“- Zielfernrohre, wenn man die Mehrzahl der Modelle so nennen darf, decken die üblichen Einsatzbereiche von Jägern und Schützen ab. Natürlich müssen, abhängig vom Haupteinsatzbereich, Gewichtungen vorgenommen werden. Wenn hauptsächlich bei Tageslicht gejagt wird, können leichte, schlanke Zielfernrohre mit 40, 42 oder 44 mm Objektivdurchmesser und mittleren Vergrößerungen (6fach, 3 - 9fach, 1,5 - 6fach) völlig ausreichend sein, da sie bis in die Dämmerung hinein gute Leistungen erbringen. Für Ansitz und Pirsch sind sie zweifellos gut geeignet. Eine 1,5- oder 2fache Vergrößerung bringt zudem die Eignung für die Drückjagd mit sich (sofern das Absehen dafür geeignet ist).
