A tendency of wide and narrow field of view modes can be seen in many thermal imaging devices. The purpose of the study is to identify differences in focal lengths and fields in the zoom lenses of thermal imaging devices based on uncooled matrix radiation receivers. The study analyzes information obtained from scientific and technical literature, and electronic resources. Differential range from 3.0 to 5.6 with average value of 3.6 was determined within the studied sample. The study will be further used for the development of a device for master thesis.
