Tamron optical products are
also at work on factory production lines. Examples include CCTV -- Closed Circuit
TV -- lenses acting as the "eyes" for FA -- factory automation, and
production of "test plates" used for accurate inspection of lens surface
accuracy in lens grinding plants.

| Tamron products work as eyes for automation
systems in factories. Image sensors monitor the movement of machines or products
moving through machines need an "eye," -- a lens -- at the sensor entrance.
Information processing provides necessary data to control the automation system,
such as the image recognition processing of images obtained through these lenses.
Accordingly, distortion compensation is rigorously applied to lenses for FA use
to eliminate any negative effects on image processing. Another feature of FA lenses
is their robust construction for operation under severe conditions. |
Ultra high precision lens series for megapixel cameras -- cameras with 1.3 million
pixels: rigorous distortion compensation is applied to image processing. |

Spherical test plates combine a concave and a convex lens. When measuring a convex
lens, a concave test plate is used. If the lens curvature is distorted from incorrect
machining, the abnormality will be detected by the Newton stripes. |
Test plates are devices used for polishing
measurements in plant manufacturing lenses. The lenses are generally spherical
with the curvature labeled as "R." As the lens is polished, the test
plate measures the accurate R of the lens. In general, the lens can only be polished
using the R of the test plates used at that plant. Tamron's test plates are widely
used at the many lens polishing plants in Japan. Tamron offers up to 2,000 different
combinations of test plates, so any optical engineer is able to design without
concern about having test plates for the machining stage. Tamron test plates are
so widely used that there is even an expression, "using the Tamron R."
In this way, our test plates contribute to the infrastructure of the optical industry.
