Pinhole inspection unit

Hamamatsu Photonics Pinhole inspection unit專門用於檢測鋁鐵罐的針孔

pinhole inspection unit for pouch rechargeable batteries: C15477

pinhole inspection unit for pouch rechargeable batteries: C15477

By making use of a photomultiplier tube with a large photosensitive area and a noise-suppression signal processing technique, Hamamatsu Photonics has developed a new pinhole inspection unit, the model C15477 that quickly finds pinhole defects as small as 1 micron (millionth of a meter or μm hereafter) in diameter in sheet workpieces. This new product can detect tiny pinhole defects only a quarter of the size of pinholes detectable up to now, and so will improve inspection accuracy for tasks such as inspecting pinhole defects in fuel cell separators for fuel cell vehicles and aluminum laminate films for pouch rechargeable batteries. This product is available as a set with a light source unit and a light collector unit optimized for inspecting pinhole defects in sheet workpieces such as large thin metal sheets measuring 480 mm wide by 180 mm deep. 

OPTICAL PINHOLE INSPECTION UNIT FOR LAMINATE FILM AND FOILS: C12570

OPTICAL PINHOLE INSPECTION UNIT FOR LAMINATE FILM AND FOILS: C12570
The C12570 series is a pinhole inspection unit designed to detect pinholes in laminate films and metal foils.
Since non-contact optical detection is used, the samples being inspected are not exposed to stress from liquid or special environments such as electric fields, magnetic fields, and electrolytic solution.
The C12570 series uses a photomultiplier tube with high sensitivity that allows detecting tiny pinholes with high accuracy.

Pinhole Inspection Unit

Pinhole Inspection Unit
The C11740 is a pinhole inspection unit specifically designed to detect pinholes in cans.
components include a high-sensitivity optical sensor (photomultiplier tube) to detect even tiny pinholes with high speed and precision. Its specifications include a large photosensitive area and an excessive light protection circuit ideal for can pinhole detection tasks.
External control input/output on the C11740 allows easy setups for in-line inspections and other tasks.
