The Tesa Visio 300 DCC is a laboratory optical measuring machine — sometimes referred to as a video measuring system or optical comparator — designed for high-precision dimensional inspection and measurement in controlled laboratory environments. Tesa is a well-established Swiss metrology brand with a long history of manufacturing precision measurement instruments and gauging solutions for quality control and industrial inspection applications worldwide.
This 2009 machine offers a three-axis measuring range of 300 mm on the X-axis, 200 mm on the Y-axis, and 200 mm on the Z-axis, making it well suited to a broad range of small-to-medium-sized workpieces. Measurement resolution reaches up to 0.5 µm, with high repeatability in the micron range, which reflects the demanding accuracy standards expected of laboratory-grade optical measurement equipment. The machine has been regularly calibrated, with the most recent calibration completed in 2025, providing confidence in its current measurement integrity.
The optical system centres on a high-resolution CCD camera paired with zoom optics and interchangeable lenses, depending on configuration, enabling flexible magnification and detailed surface inspection. Illumination is provided by LED lighting covering both top and bottom positions, supporting both surface lighting for reflected-light inspection and contour lighting for profile and edge measurement — a combination that broadens the range of measurement tasks the machine can handle without additional equipment.
The measuring table is a granite surface plate, chosen for its dimensional stability and resistance to thermal variation, and is rated to carry workpieces up to 20 kg. Power requirements are 230 V at 50 Hz, consistent with standard European mains supply. The machine is offered with a PC-DMIS software licence included, delivered on a USB dongle, giving the new owner immediate access to one of the most widely used metrology software platforms for part programming and measurement reporting.
The machine is used, located in Germany, and has been operated in a laboratory environment.
