Silicon Carbide(SiC) has become a promising material in semi-conductor industry, due to the development of SiC material manufacturing and the decrease of the cost in recent years.
Silicon Carbide (SiC) is a wide bandgap material and is the typical representative of the third-generation semiconductor materials. Due to the wide bandgap, high thermal conductivity, high saturated carrier mobility, high threshold breakdown electric field strength, and high chemical stability, it is an ideal substrate for the fabrication of power electronics and radio frequency devices operating at extreme environments, such as high temperature, high frequency, high power, and strong radiation. Therefore, SiC has extensive applications in white-light illumination, automobile electronic, radar communication, aeronautic and aerospace, and nuclear radiation.

Jewel Bearings are precision miniature components typically made of synthetic sapphire and ruby because of their superior hardness and ability to accept a high polish.
Synthetic sapphire exhibits exceptional performance of high hardness, high strength, scratch resistance, corrosion resistance, and small coefficient of friction. Jewel Bearings out of sapphire are ideal material for instruments, meters, control devices, precision mechanisms where low friction, long life, and dimensional accuracy are important. Due to its high temperature resistance and chemical durability, sapphire jewel bearings are particularly useful for the applications in Petrochemical, Process Control and Medical Instrumentation. Sapphire Jewel bearings present highly consistent static friction and low kinetic friction. sapphire-on-steel has a static coefficient of friction of 0.10~0.15. Jewel bearing surfaces maintain their smoothness even after decades of use, which means jewel bearings have very low friction variability.

Infrared targets(IR targets) are used for testing thermal imagers operating at MWIR-LWIR spectral band. We can manufacture a wide range of IR targets by creating precision holes of different shapes, including 4-bar, circle, cross, semi-moon (semi-square), triangle etc in thin metal sheets. The surface of the metal sheet can be coated using high emissivity coating (Emissive IR targets) or polished to achieve high reflectivity (Reflective IR targets). Both types of IR targets will generate the same test results if used properly.
Emissive IR targets can be considered as classical well known targets that are manufactured by coating metal sheet with hole by diffusive black paints or by carbon deposition in vacuum chamber.
Reflective targets are manufactured by polishing metal sheet to achieve high reflectivity in infrared band.
Types of Targets and dimensions:
Bar targets
Square targets
Slit targets
Cross targets
Pinholes
Customized targets as customer request
