Keyence has extended its IM series of digital profile projectors with the IM-6225 model, featuring a multiple ring illumination unit. An automatic search function for optimum lighting parameters helps the user to select the lighting best suited to the nature of the part to be inspected and the measurement to be carried out.
The Keyence IM Series digital profile projector has revolutionized quality control processes on the shop floor, in the laboratory or at the production line. This imaging system performs dimensional measurements automatically, at high speed and with extremely high precision. The operator places the part to be inspected on the stage and presses the button on the front panel to measure up to 99 dimensions in just a few seconds, with an accuracy of up to +/-2 µm. Measurements are carried out using the part's backlight (diascopy) or direct illumination (episcopy).
To further extend the range of applications for the IM series, Keyence has added a new model to its range of measuring heads. The IM-6225 measuring head is equipped with an innovative illumination device that considerably increases the possibilities of episcopic illumination, thereby extending the measurement spectrum to include parts requiring specific lighting conditions. Like all IM series models, this ring light is dimmable, and its four segments can be activated independently of each other.
These traditional settings are complemented by two innovative features: motorized adjustment of lighting height and choice of lighting type. The IM-6625's lighting unit incorporates two lighting technologies within the same ring, for multi-angle or grazing lighting. Multi-angle lighting in the upper position illuminates all parts of the target uniformly. Low-angle lighting enhances the contrast between the target and its circumferential contour, while high-angle lighting creates contrasts between the different heights of the target. Depending on the nature of the target and the measurements to be carried out, it is thus possible to choose the optimum lighting characteristics: height, light intensity, ring segments to be activated, type of illumination.
To simplify the user's task and avoid wasting time searching for the best lighting parameters, Keyence has equipped the IM-6225 with an automatic search function for the optimum lighting. Once the operator has specified the characteristics of the part to be inspected, this function displays on screen 2 to 4 actual images of the part taken under different lighting conditions, together with the associated measurements. The operator then selects the most appropriate lighting for his application.
The IM-6225 measuring head is accompanied by the launch of the new IM-6700 controller, with enhanced performance and a software version for automatic control and parameterization of the multiple illumination unit. This new version of the programming and operating software, which can be downloaded free of charge for users of other IM series models, has also been made even more user-friendly and ergonomic. Measurement sequences are now even easier to program and operate.
