Transparent Spinel Spherical Window Descriptions

Transparent spinel, also known as magnesium aluminum transparent ceramics, finds diverse applications in optics, electronics, and structural components.

Transparent spinel is adept at crafting windows and lenses spanning the visible to mid-infrared spectrum. The theoretical transmittance of 3~5μm closely approaches 87%, aligning with materials like ALON and sapphire. Notably, it exhibits superior performance in mid-infrared imaging systems with a cutoff wavelength slightly longer than both counterparts.

The properties of transparent ceramic spinel mirror those of alumina, making it suitable for various high-performance substrate materials in applications such as thick film circuits, thin film circuits, integrated circuit carriers, and chip packaging.

Transparent Spinel Spherical Window Features

Transparent Spinel Spherical Window offers several advantages:

  • Resilience against scratches under harsh conditions.
  • Significantly reduced thickness (by more than 60%) under the same protection requirements, leading to effective weight reduction.
  • Improved protection ability under the same thickness.

Hence, it is suitable for diverse applications in high-temperature, high-pressure, and corrosive environments, including equipment observation windows, gas detector windows, high-temperature boiler water level gauges, commercial barcode scanner windows, downhole detection sensors, low-voltage and high-frequency capacitors, and various goggles.

Transparent Spinel Spherical Window Applications

  • Spherical optical Windows, lenses, prisms

Transparent Spinel Spherical Window Packaging
