Recently, optical components employing minute surface pattern in nm order have been manufactured in injection molding. Among the optical components, diffraction lens of printers and light guide panels used for liquid crystal displays require the precise transcription; however, the transcription mechanisms of these micro surface patterns has not been clarified in detail. It will be essential to establish the transcription model to predict the quantitative transcription property as a function of molding conditions, since the micro surface patterns will become high density and also require the precise transcription. Therefore, we have conducted the injection molding experiments to reveal the effect of molding conditions on the transcription property of micro multiple V-grooves. By measuring the transcription heights of the V-grooves fabricated under various molding conditions, we confirmed the following results: (1) The transcription ratio increases with increasing the mold temperature and the compression pressure; (2)The transcription ratio of small V-grooves are higher than that of large V-grooves whose width is about 0.1 mm.
