Problem statement. Traditional methods of manual adjustment and visual checkout have the following disadvantages: high labor intensity, low measurement accuracy, low time stability and reproducibility.

Purpose of the article. To increase the accuracy and reproducibility of the alignment, as well as the objectivity of measurements by eliminating negative influences of the operator, such as turbulent heat flows introduced into the optical path, manual adjustment errors, subjectivity of visual measurements.

Results. An adjustment technique has been developed to ensure the setting of the relative position of the main and secondary mirrors within the specified strict tolerances. The main principle of adjustment technique is the division of the task into preliminary setting of optical elements on a geometric axis and subsequent calculation of the position of the optical axis, as well as the use of automation tools in all control and measuring equipment.

Practical significance. The application of the obtained results in the creation of large-sized two-mirror lenses will reduce the complexity of the adjustment process and increase accuracy and reproducibility.
