    Automotive suppliers: Company A

    Appearance inspections that require a lot of vision systems. Fluctuations in inspection accuracy. Learn how they solved the problems unique to working with large parts.


    Company A provides parts to a major automobile manufacturer, with an established record for large components. They considered building a more accurate and efficient appearance inspection system in line with the recent demand for higher quality standards and shorter delivery periods. However, they had the problems unique to large parts.

    Household goods manufacturer: Company B

    Too many different sizes and shapes of items to inspect. Learn what is most essential to creating an inspection system that covers a wide range of conditions.


    Company B, a leading household goods company, manufactures and sells various products essential to daily life. There are many types of products and many different shapes of containers. And new products are coming out all the time. Every time a new container was used, they had to verify the inspection system's ability to detect container defects and printing errors, which took time and labor. In addition, the company was also troubled with the number of defects that could not be recognized by the new inspection system.

    Container manufacturer:Company C

    Product inspections take too long. 
    Learn what the keys to efficiency enhancement are.


    Company C manufactures various containers and wished to enhance the accuracy of their inspection system to be doubly sure about their product quality. On the other hand, they had a problem in that inspections were taking too long because they manufacturer many different kinds of containers in very large quantities. It was an urgent task for them to establish a system that enables more accurate and efficient inspections.

    A manufacturer of 3D measurement equipment: Company D

    The optical axis shift causes an error in inspections. Why does a manufacturer that requires high accuracy would opt for reliability?


    The Company D, a manufacturer that delivers 3D measurement equipment to various types of businesses, performs inspections and precise calibration of all lenses used for the equipment before providing them to users. However, the optical axis of lens may be shifted by shock or vibration after operation startup, thereby hindering accurate inspections. Therefore, selecting a lens with shock-resistant and anti-vibration functions after operation startup is a challenge.

    A lens is adopted for a high-precision semiconductor inspection equipment.
    What is the decisive factor in the selection of a semiconductor manufacturer?


    “We would like you to propose a lens that can be used assuredly for the new semiconductor inspection equipment that we are developing.” The semiconductor inspection equipment manufacturer said so, and consulted with the system integrator S. However, the company S could not determine a way to evaluate the quality and performance of lens suitable for high-precision semiconductor inspection in which an error even in units of micron is not permitted.

    System integrator M

    The actual resolution performance of a lens cannot be learned by specification.
    What is the key tool to recognize it clearly?


    The system integrator M was selecting a lens based on the catalog specifications in accordance with requirements of the company’s inspection vision system. However, they felt frustrated by not being able to constantly provide the best lens because lenses with the same specification by different manufactures varied greatly in the resolution performance.
