Replicated diffractive optics
Replicated diffractive optics
Replicated continuous-relief diffractive optical elements (DOEs) are made by conventional injection-molding methods. A master is fabricated to customer specifications by direct-write electron-beam lithography with u¥to 64 phase levels and pixel sizes as small as 0.5 µm. Calculations by an iterative algorithm produce desired illumination and intensity patterns in the DOEs.
