Formulation of the problem. Optical systems price and quality depend on the requirements for focusing accuracy validity and the measurements objectivity at the focusing stage of optical systems manufacturing.

Purpose of the article. Increasing the measurements objectivity at the focusing stage of optical systems manufacturing. Objective measuring of 3 values – the focusing range, the optimal focusing position and the focusing accuracy – from the "focusing function" constructed from the spatial distribution of the point spread function measuring.

Results. It has been found that by measuring the spatial distribution of the point spread function and constructing the "focusing function" it is possible to measure the focusing range, the optimal focusing position, and the focusing accuracy. Measurement schemes for typical optical systems are presented. The ranges of typical optical systems parameters were calculated.

Practical significance. Obtained results could be used in the optical systems development and assembly.
