Главная оптическая ось – это прямая, следующая сквозь линзу перпендикулярно ее плоскости, причем она идет сквозь центры сфер, локализующие грани линзы (через главные фокусы).

Объяснение:

Оптический центр (О) – место пересечения главной оптической оси с линзой. Луч сквозь оптический центр, не преломляется.

Побочная оптическая ось – всякая линия, следующая сквозь оптический центр О.

Главный фокус линзы (F) – точка, размещенная на главной оптической оси, в ней пересекаются либо лучи, либо же их продления.
