Tester and adjuster for opto-electronic systems - with optical axes of various optical systems at large distances from each other

A collimator (AK) is used, and has a triple strip optical system (TO) whose length is sufficient to bridge the distance between the transmitter optical system and the other (receiver, sighting device and possibly camera tube) optical systems. It consists of a part (TS) of a triple strip divided across its length, and of a ray splitting mirror (ST) at an angle of 45 deg. to the triple strip longitudinal axis, replacing the other part. A coherent transmitter ray (S) is projected to infinity by the collimator lens, and the triple optical system ray splitting mirror is placed between transmitter optical system (SO) and the collimator lens (LKI).
