This review describes the step-by-step development and updating of the optical multipass system with a fixed path length and large relative aperture. Including some breaks in the work, the system has been improved for many years. The models were designed using the ratio between the base length of the multipass system and the focal length of an objective equal to 1.5, that ensured the development of a cycle of six-pass systems with a single objective. Of special interest is an original scheme with f number equals f/3.7 to be applied in high resolution spectroscopy. This brief review deals with various types of multipass systems developed for urgent high resolution spectroscopic applications in the Russian Academy of Sciences. Some of them have been widely acknowledged and independently applied in different fields of modern science and technology: i.e. laser techniques, metrology, spectral instrument engineering, and environment.
