High hardness of Sapphire Lens

Product Description

In some cases it is easier to carry out temperature measurements by means of traditional thermocouples, but in aggressive medium these quickly break down.

Thermocouple casings made of sapphire in the form of tubes with hermetically sealed bottoms provide reliable protection of metallic thermocouples from aggres-sive media.



Although there are lots substrates which are regarded as potential materials to replace Sapphire Substrate, it is still dominated in the substrates (for GaN LED growth) market, because of its reasonable price and relatively low mismatch. Zhongju is capable of processing substrates according to customer needs. Currently, our sapphire substrate productions ranges from 2 to 12 inches with high quality and accurate orientation.
