Various industries need Telecentric Illumination for measuring and inspecting for defects. Here are some of the industries that use telecentric illuminators.
Precisely inspecting and measuring automotive parts
Automobile manufacturers have a responsibility to make sure that the cars released to the market are of high quality. You may have come across events where automobile companies
recall cars because of defects. It is both expensive for the companies and affects their brand positioning in the market.
To this end, quality inspection and gauging of vehicle parts are critical. Among the applications include measuring the precise distance from the center to the edge of a car’s accessory. One of these car accessories is engine fuse boxes which are the guardians of the electrical components in cars. You can inspect to see if the holes in them are through without any burrs and also measure their diameter.
Precise inspection and measurement of 3C products.
The 3C industry comprises consumer electronics, computers, and communications. Applications of telecentric illumination in the 3C industry include high-precision measurement of smartphone covers. This is done by a telecentric illuminator that provides accurate measurement and a great view of the center and edges around it.
You can also use telecentric illuminators to measure phone glass screens, smartphone card slots, home buttons, and smartwatch cases. Since mobile phones are constantly being updated, it calls for higher precision testing requirements during production. Telecentric lighting allows almost nil distortion, and a larger depth of field because of the parallel optical path’s design.
Detecting defects and measuring dimensions accurately in metal parts
Metal parts and products also need to be visually inspected for defects. Such defects include dents, cracks, burrs, uneven color, and scratches that occur during production.
Telecentric illumination also performs thread detection on fine mesh, screws, nuts, springs, and bolts. The silhouette produced is sharper with very minimal to no distortion on the image quality. Furthermore, the illumination provides a uniform display of the periphery as well as a bright center. This maximizes the lens’s resolution and improves its measurement accuracy.
Other applications of telecentric lighting in the metal industry include high-precision measurement of metal gaskets and other metal parts. Metallic gaskets seal high-pressure and temperature applications such as condensers, heat exchangers, and compressors.
Precisely inspect medical containers
Telecentric illumination is widely used in the medical industry for its low-distortion and high-resolution images. It is used to inspect defects that standard backlight illuminators cannot, like the detection of flaws in glass bottles. The defects inspected in glass bottles include neck cracks, mouth gaps, and mouth cracks which are health hazards to both patients and hospital workers.
In addition, the special structure of the telecentric illuminator helps the imaging not to be blocked by the refraction of light that goes through the bottle. This means that it is easy to detect defects as little as small scratches on the glass bottle.
Precisely track the movement trajectory of fish in water
Another use case for telecentric illumination is drug testing on fish. Some pharmaceutical companies are in the developmental and experimental stages of drugs using small fish in tanks. When you observe fish in water through a glass fish tank, the image is usually magnified and distorted because of refraction. This makes it hard to clearly see the actual position of the fish in the tank.
To study the drug effect on the fish, its movement trajectory is carefully recorded using telecentric illumination. This is because it provides a clear silhouette of the fish with no distortion thereby helping to track its movement.
Conclusion
Telecentric illumination has found wide applications across various industries by providing the foundation of low distortion and high resolution required for precise inspection and measurement. It has enabled automakers, 3C producers, metal manufacturers and pharmaceutical companies to maintain high quality standards and work efficiency through defect detection and dimension gauging of parts and products.
