Synthetic Quartz Crystal for Optical Componet


Since quartz crystals are birefringent, they can be used as birefringent plates or wave plates.


■Optical Activity

Quartz crystals exhibit optical activity, or the ability to rotate the plane of polarization when linearly polarized light passes through its interior.
They can be used for devices that analyze liquids, such as a saccharimeter.

Optical Activity


■High Quality

  • With few internal crystal defects that affect optical characteristics and a low density of foreign matter in the crystal, this synthetic quartz crystal is ideal for optical applications.
  • It possesses extremely high refractive index homogeneity based on crystal growth of high purity and low crystal defects.

Precautions for Use

Make sure to read the following carefully before using synthetic quartz crystals:
Crystal quartz changes from α crystal to β quartz crystal at a temperature of 573℃ because of phase transition. This phase transition is reversible, but transition from β quartz crystal to α crystal does not take plase homogeneously, and twins are created. Therefore, careful attention must be paid to never allow the temperature to rise above 573℃.
