The Outstanding Advantage For Sapphire
1- Thinner and Stronger than Standard Glass Windows
2- Transmits Wavelengths Ranging From UV to Mid-Infrared
3- Features Extreme Surface Hardness and Chemical Resistance
sapphire physical property
| Product Name: | Aluminum oxide (Al2O3) crystal substrate Sapphire crystal glass |
| Product Description: | Al2O3 single crystal (Sapphire, also known as white stones,
sapphire) has good thermal properties, excellent electrical
characteristics and dielectric properties, and
anti-chemicalcorrosion, it is high temperature, thermal
conductivity, high hardness, infrared transparent, chemically
stable good. Widely used in high-temperature infrared window
materials and III-V nitride epitaxial film substrate and a variety
of materials to meet the growing blue, purple, white light-emitting
diode (LED) and blue laser (LD) needs, Branch Crystal company
specializing in the production of high quality polished sapphire
crystal and epitaxial substrates will provide you with a lot of
high quality and low price monocrystalline substrate. |

Applications of sapphire product in Medical
· Sapphire is used in surgical systems for laser transmission and
in contact with bodily fluids.
· Surgical tips - sapphire is used in contact tips for various surgical laser
applications
· Endoscope lenses - sapphire is often used in endoscope lenses due to its durability
in contact with tissues and in sterilisation environments such as
autoclaving
· Sapphire knives - with a sapphire knife, thinner sections are possible. The near
perfect cutting edge of this knife / blade gives distortion-free
sections down to 10 microns thick.
