Abstract	For micro-optical products, hot embossing process seems to have more merits because of small thermal cycle that improves optical and mechanical properties and low material flow that reduces the internal residual stress. This study investigates the effects of processing conditions on the birefringence distribution, directly affecting optical quality, in V-grooved optical products. A hot embossing machine was designed and manufactured. Dimensional accuracy and low birefringence are strongly required with respect to the replication accuracy and optical quality.
