Description

Cher Circle Glasses is a single crystal form of corundum, Al2O3, also known as alpha-alumina, and single crystal Al2O3,have 9.0 hardness.
Sapphire is aluminium oxide in the purest form with no porosity or grain boundaries, making it theoretically dense.
The combination of favourable chemical, electrical, mechanical,optical, surface, thermal, and durability properties make sapphire a preferred material for high performance system and component designs. For various semiconductor applications,
sapphire is the best choice in comparison with other synthetic single-crystals.

Products Highlights:
1).Ideal choice for excimer laser application
2).Low absorption and high damage threshold
3).Transparent in UV, visible and infrared
4).Parallelism <1 arc minutes
5).Lower color difference compared with other infrared materials
6).Different grades materials for option.
7).High precision & high surface roughness;
8).Sizes can be customized as per the customers’ request
9).Quick lead time and delivery time.
10).Matching super optics custom and processing capacity, including Moulding, CNC machining, Polishing, Particle beam processing, Magnetic flux conversion processing, Grinding, Coating, Lightweighting, Custom Shaping, Counterbores, Drilling & Coring, Edge & Bevel Polishing,3D Contouring, Bevels & Chamfers, Steps & Slots, Laser Cutting & Marking, Metrology & Inspection, Precision Pitch Polishing, Double-Sided Polishing, Optical Assembly, Measuring, etc.
11).Excellent post-sale quality warranty, with “3R”-return, replace & refund policy
