We analyzed the fundamental relationships among general optical system parameters assuming a diffraction limited imaging in paraxial space. We discovered that the total twelve optical system parameters, which describe the optical imaging problem, are unambiguously determined by a set of four of these parameters under a diffraction condition. This condition is set so that the object image permitted blur is of the same size for both the spot due to defocus and the diffraction spot. There can be found, in total, 314 different optical system design approaches to fully describe the diffraction limited imaging problem. In our paper we presented eight of these design approaches. The Web Application allows the user to find diffraction limited imaging parameters according to the relations presented in the paper. It also shows a graphical solution for computed parameter's values. 
The Web Application window contains fields:
Input data section contains three input fields:
