TEW's optical Components are the products utilizing the optical property (double reflection) of quartz crystal. TEW is producing high grade optical components by using selected defect-free grade synthetic quartz crystals.
Quartz crystal wave plate is an optical device to produce phase difference between ordinary and extraordinary ray by using double refraction property of quartz crystal. The wave plates are used for optical pickup of DVD and for liquid crystal projector.
The quartz crystal has a better balance in both thermal conductivity and cost when it is compared with the current sapphire or glass substrate.
