It is very easy to operate. Once the part to be measured is ready, the operator needs only to press the only button on the device. The telecentric optical system automatically adjusts the correct camera distance and the right lighting. The visual result appears on the monitor – with all of the dimensions of the detected geometric elements. The inspection parameters can now be selected. At the same time, the device suggests a measurement routine for future inspections. The respective correct illumination is crucial to performing optical measurements. It influences important parameters such as the depth of focus, whereby imprecise settings would lead to measurement errors. For this reason, ZEISS O-SELECT is equipped with high-power, flexible light components from SCHOTT: first, a beam that shines from below for measuring contours and broken parts; second, an incident light, which, for example, illuminates depressions, edges or slanted surfaces from above. The latter consists of a double ring light that features 160 LEDs in eight segments that can be controlled individually. ”By using extensive optical simulations and optimizing each LED, we were able to achieve extremely homogeneous illumination – for maximum contrast and the best possible test requirements,” explains Dr. Bernd Wölfing from SCHOTT. The meter calculates the appropriate illumination intensity for the light components automatically, depending on the properties of the workpiece and the position of the inspection traits. Thus, gaps, radii or angles in punching and bending parts, injection molded or laser cut workpieces, such as those used in the automotive industry and medical technology, can be recorded without error in a very short period of time. ”Realizing the complex interplay of optics and illumination meteorologically and automating it makes the measurement traceable, reproducible and therefore reliable,” says Andrzej Grzesiak, Director of Metrology Systems at ZEISS. <
