Transparent Spinel Customized Part 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.
