The invention discloses a design method of a micro projection compound eye collimating collecting lens. The design method is characterized by comprising following specific steps: (a) a simulation method is firstly used to check a compound eye focus; (b) the design of the compound eye collimating collecting lens is adjusted in an original ZEMAX lighting path, and a back focal length is gradually increased until the focus is on a DMD working surface during simulation; and (c) two parameters including a defocused spot and a wave aberration are used for optimization in the ZEMAX, so as to get the micro projection compound eye collimating collecting lens to meet the requirements.
