CM4062 Transparent Spinel Sheet Description

Transparent Spinel Sheet Descriptions:

Transparent spinel (Magnesium aluminum transparent ceramics) has many applications in optics, electronics and structure.

Transparent spinel can be used to prepare visible to mid infrared windows and lenses. The theoretical transmittance of 3~5μm is close to 87%, which is close to ALON and sapphire, and the cutoff wavelength is slightly longer than both, especially in the mid-infrared imaging system performance.

The properties of transparent ceramic spinel and alumina are similar. It’s suitable for various circuit components such as thick film circuit, thin film circuit, integrated circuit carrier and chip packaging and other high-performance substrate materials.

Transparent Spinel Sheet Features:

Transparent Spinel has the following advantages:

-no scratches under harsh conditions;

-the thickness can be reduced by more than 60% under the same protection requirements, and the weight can be effectively reduced; 

-in the case of the same thickness, the protection ability can be improved.

 

Therefore, it can be used in various high temperature, high pressure and corrosive environment of equipment observation window, gas detector window, high temperature boiler water level gauge, high temperature and high pressure equipment observation window, commercial bar code scanner window, downhole detection sensors, low voltage and high frequency capacitors, all kinds of goggles, etc.

Transparent Spinel Sheet Applications:

Transparent spinel (Magnesium aluminum transparent ceramics) has many applications in optics, electronics and structure.     

Transparent Spinel Sheet Packaging:

SAM’s Transparent Spinel Sheet is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
