The invention provides a parallel micro-compensation device which comprises a moving platform, a substrate, three brackets, three first moving assemblies and three second moving assemblies. The movingplatform is of a equilateral triangle shape, and each end point of the moving platform is correspondingly connected to one first moving assembly and one second moving assembly; the three first movingassemblies and the three brackets are fixedly connected to the substrate, and the three brackets and the three first moving assemblies are parallelly arranged correspondingly one by one; one second moving assembly is fixedly connected to each bracket, and each second moving assembly is arranged vertical to the corresponding first moving assembly; each first moving assembly is used for driving thecorresponding end point to be close to or far away from the substrate, and each second moving assembly is used for driving the corresponding end point to be close to or far away from the corresponding bracket. The device is small in size and simple and compact in structure, has the characteristics of being relatively good in rigidity, stability and the like, and can achieve six-degree-of-freedommicro-compensation by means of simple control.
