Customize C-axis Al2O3 sapphire bearing sapphire rings Hardness 9.0

Sapphire Materials:
Sapphire is grown using various different methods, each with its advantages. By offering Sapphire grown by Stepanov, Czochralski, Kryopolus and HDSM methods, Roditi ensure that the specification is met with the best production time and cost in mind.
Boules, Ingots and Blanks
Unprocessed, single crystal Sapphire takes the form of a boule before being cut and polished into the required forms.
The boule is a large, cylindrical-like piece of Sapphire with no ground, polished or flat faces and offers any crystallographic orientation of components, such as c, m, r and a-cut. Because of Sapphire's tremendous hardness, the cutting and processing is done with diamond tools.
Boules such as this are processed into blanks and ingots ready for further processing and polishing. Such blanks and ingots are uniformly shaped, usually as cylinders, and have ground surfaces.

Sapphire Components
Sapphire's range of superior qualities make it ideal for optical and non-optical components. From the forward-facing optics of imaging systems to the thermal insulators in plasma systems, Sapphire's performance at extreme physical conditions often make it the preferred choice for the following:

Lightguides
Sapphire offers higher working temperatures in applications such as temperature thermometry and IPL systems, with a broad transmission.


Lenses
High optical quality Sapphire is used for lenses in systems that require durability and ruggedness where standard materials suffer from grit, impact and temperature damage. Sapphire lenses also offer high performance in laser devices, offering high thermal conductivity.

The broad transmission of Sapphire, across visible and NIR spectrums, make it ideal for FLIR imaging systems in hazardous environments, or where the reduced thickness of Sapphire lenses lead to reduced system footprint.

Tubes
Sapphire tubes, made using the Stepanov growth method, replace glass and quartz tubes in high temperature and pressure systems such as plasma applications and insulators.


Pins and Rods
As well as the optical proporties offered by Sapphire rods for fibre optcal and light-guide applications, the physical strength and inert nature of Sapphire make it ideal for engineering and structural uses.
