Eliminate new defects generated during transportation and storage, reducing production risks.
Provide accurate seed quality data support for new material R&D and special crystal preparation.
Fast and accurate inspection before loading the seed into the crystal puller, preventing failures such as ingot breakage or polycrystalline inclusions during the pulling process.
Detect internal cracks (invisible to the naked eye) and surface defects in seeds: surface cracks, scratches, crescent marks, edge chipping, processing marks, etc.
Precise measurement of large-end diameter, small-end diameter, taper, and length.
Automatically identify codes on seeds for traceability.
Analyze internal stress distribution in seeds to prevent breakage during crystal pulling.
Reserved interface for automatic feeding to enable automated loading.
Reserved MES interface for data upload.
Adjusts the camera angle to fill the blind spot in the traditional method at the seed's tapered neck, capable of identifying multiple defects.


Adopts a parallel optical scheme to eliminate specular reflection, resulting in sharp edges and high dimensional measurement accuracy.


The high dynamic range infrared camera easily switches detection modes for both pre- and post-acid washing processes.
Detects stress distribution in seeds to prevent breakage caused by excessive stress during crystal pulling.
