Product Description

sapphire glass ball,diameter10mm Al2O3 single crystal ball lens ,Ruby ball ,dia10mm sapphire half ball ,Al2O3 single crystal lens by customized


1. Sapphire Ball Feature


Balls&balls measuring head jewels are made of synthetic sapphire/ruby. It is largely used in

heavily corrosive environment and optical fiber communication because of its anticorrosion,

wearable and fine transmission characteristics. Balls measuring head jewels are used as insulated

measure head on precise instruments.

The level of optical sphere lens is up to level 3, the ball diameter from0.4-250 mm,the tolerance

is ±0.001. Application is mainly used in laser, optical communication, infrared applications,

and medical imaging, photovoltaic industry, and other fields. We can provide the optical

communication spherical lens, sapphire ball lens, zinc selenide ball lens,K lens,calcium fluoride,

germanium silicate glass ball, zinc selenide glass lens. technological level

of quality can be better than Japan, Germany.

2. Feature of our Optical synthetic Sapphire crystalsapphire optical steps window, Al2O3 single crystal glass lens,  optical steps polished lens by sapphire

Sapphire is a single crystal form of AL2O3.Single crystal

sapphire possesses a unique combination of excellent

optical, physical and chemical properties. Sapphire

retains its highstrength at high temperature, has

good thermal properties and excellent transparency.

It is chemically resistant to common acids and alkali

working temperature up to 2000. These properties

encourge its wide use in hostile environment where

optical transmission in the range from untraviolet to mid-infrared.
