The paper describes a way of simple optical systems design. The presented computer tool synthesizes "photographic objective" type systems according to given aberration parameters. It is directly applicable to micro objectives, which are photographic systems in a backward ray trace. The paper compares lenses with f’=50 mm, NA=0,1, 2y=6 mm designed as cemented doublet plus single lens and as pair of cemented doublets. Despite the second lens is a more complex system, its image quality is no better than provided by simplified system.
