The necessity to measure precisely, together with the development of complex surfaces, or of surfaces that cannot be touched during the process, trigger the development that the use of contactless technologies for detection and measurement is currently living through. Sensors of multiple shapes and sizes, based on different functioning principles, are being launched on the market. (more…)

An inexpensive and high-resolution microscope has for the first time been engineered to fit onto a single chip. The performance of the device is comparable to a 20x microscope, but in terms of size, cost and ability to mass produce, the device has significant advantages. (more…)

The referencing or alignment of a checking fixture can be done in two different ways: geometric system or 3 points system.
