A Study of Two-Stage Micro Injection Compression

This research aimed to develop a novel two-stage micro injection compression molding (-ICM) process for fabrication of plastic diffractive optic elements (DOE). The DOE was designed with the spherical coefficients and the Fresnel lens. A piezo actuator was installed inside the mold plate for activating the mold insert for the second compression motion for micro ICM of the DOE lens.
