Product Description

General Introduction:
Raytek's uncoated sapphire window is suitable for harsh conditions, including high temperature, high pressure, strong vacuum or corrosive environments. Sapphire has high compressive strength and strong acid resistance.
Unique characteristics of sapphire materials
Sapphire is a single crystal form of alumina, which has good chemical, mechanical and optical properties. Sapphire is resistant to strong acid corrosion and can be used in corrosive environment. The surface is scratch resistant and wear-resistant, with a Knoop hardness of 1800 parallel to the optical axis (c axis) and 2200 perpendicular to the optical axis.

Lens Substrates:
Sapphire 

Optional I:	Sapphire Substrates from CORNING, OHARA, SCHOTT, LEONI, AGC,HELLMA, NIKON,VITRON,ETC
Optional II:	Equivalent Sapphire Substrates Made in China, C-laser own brands

Uncoating:
Wide transmission range
The uncoated sapphire is transparent in a wide wavelength range from 170 nm to 5.5μM

Main Applying:

Applying Fields I:	Harsh optical applying conditions. Make an observation window to observe the interior of vacuum cavity or cavity containing high temperature plasma
Applying Fields II:	Other
*****
