What we can solve:

Our Micro-Vu Excel 701 optical measuring instrument has a measuring range of 660 x 700 mm and a maximum Z-axis range of 160 mm. We use it primarily for the inspection of our products, but we also offer measurement services to our customers. The measuring instrument has a very high measuring accuracy, specifically 2.8 + L/200 µm. The accuracy depends on the size of the part, so for example for a measurement dimension of 100 mm the tolerance of the measurement accuracy is +/- 3.3 µm, i.e. +/-0.0033 mm. The resolution of the optical measuring sensor is 0.05 µm and the machine can accommodate a part with a maximum weight of up to 100 kg. Thanks to these top parameters, we can measure parts very precisely and also present the measurement results in the form of a dimensional report. The measurements take place in a separate, purpose-built, air-conditioned room with stable temperature and humidity and the machine is regularly calibrated by expert technicians. This enables us to achieve the highest possible measurement accuracy.

What materials do we work with?

Virtually all solid and permanent materials can be measured optically. Some materials may have inaccuracies due to surface imperfections. Typical examples include fabrics that have uneven edge surfaces with burrs. Optical measurement is suitable for metals, engineering plastics, thermal insulation materials and many other materials, not only industrial. We use our optical measuring instrument primarily for the inspection of our parts, i.e. we mainly measure seals for hydraulics and pneumatics, flat seals and milled parts made of engineering plastics and other industrial materials.

How is the optical measurement of parts produced?

01
Determination of requirements, assessment of technical drawing
Based on an assessment of the specific part, its material and also the tolerance requirements of the technical drawing, we evaluate whether the part is suitable for optical measurement.
02
Preparation of measurements
Depending on the nature of the part, we select the appropriate method and technology of measurement and determine which dimensions to measure. We ideally use .dwg / .dxf documents, which make it much easier to set up the measurement technology for complex parts.
03
Optical measurement of the part
The measurement itself follows. Measurements are taken in a special air-conditioned room with constant temperature and humidity to ensure consistency and accuracy.
04
Issuing a dimensional report
The measurement results are entered into a dimensional report where the measured dimensions are clearly presented and it is determined whether the part meets the required dimensional tolerances.

Frequently Asked Questions

Optical part measurement is a non-contact method of checking dimensions and shapes using a camera system. The Micro-Vu Excel 701 uses high-precision optics and software to quickly and accurately evaluate product geometry without the need for mechanical touch.

The measurement accuracy of the Micro-Vu Excel 701 is 2.8 + L/200 µm, which typically means an accuracy in the range of 3-6 µm depending on the size of the part to be measured. This allows the inspection of even very precise technical parts and components.

The main advantages of optical measurement with Micro-Vu Excel 701:

  • non-contact measurement (no deformation of the part)
  • high inspection speed
  • also suitable for soft materials (e.g. plastics, rubber)
  • possibility of automation and repeatability of measurements
  • ideal for small and complex shapes

Our optical measuring instrument has a measuring range of 660 x 700 mm and a Z-axis range (part height) of 160 mm. The maximum weight of the part to be measured is 100 kg.

The part is placed and positioned on the measuring table of the Micro-Vu Excel 701, where the camera then captures its image. The software then automatically evaluates dimensions, angles, positions or tolerances according to the drawing documentation. Measurement can be manual or fully automated, which is particularly suitable for large series.

Optical measurement on the Micro-Vu Excel 701 is ideal when:

  • risk of deformation during touch measurement
  • high inspection speed is required
  • small or complex geometries are measured
  • repeatable inspection in production is required
  • visual inspection of edges and profiles is crucial
