/kɒlɪˈmeɪʃən/

Etymology: noun of action < collimate v. = erroneous 16th cent. Latin collīmātio, French collimation. The proper word would be collineation.

a. The adjustment of the line of sight of a telescope, etc. line of collimation: the line of sight or optical axis. error of collimation: the amount by which the line of sight deviates from its position of accurate adjustment.
