Abstract. A photographic optical system with a lens designed for an object located at infinity and an image located in the rear focal plane is investigated. Matching criteria for the optical system (lens) and the receiving surface (CCD or CMOS receiver) related to the assembly, adjustment, and material base of the system are formulated. Examples of matching optics with a flat and non-flat receiving surface using the proposed method are given. Taking into account the selected matching criteria during assembly and adjustment of the lens and receiver allows for installing the receiver in the plane of the best image quality. Using a receiver with a curved photosensitive surface changes the order of calculating the matching criteria. The proposed method for matching lens and receiver can be useful in designing optical systems, developing receiving devices, and also in assembling and installing the lens for correctly assessing the permissible values of linear and angular deviations.

Keywords: receiving module, photographic system, curved photosensitive surface, lens depth of field, image field curvature
