Conoscopic Probes set to transform Industrial Metrology

Spectrum Metrology has just launched a revolutionary non contact gauge and measuring system: The Conoscan creates extremely precise 3-dimensional digital images of virtually any surface – including the most difficult to measure components – at very high speeds, and at stand-off distances once considered unfeasible.

The technology behind this revolutionary system is "conoscopic holography", which is the optical interference effect produced by doubly refracting crystals illuminated with convergent polarised light rays. This technology, protected by 8 patents, solves the problems traditionally caused by awkward shapes, angles, materials or sizes. Applications are wide ranging and include the thickness of high density PCBs, radius and steep angle measurements of moulded plastics products and dimensions and radii of any precision machined parts.

One of the most important benefits of conoscopic holography is that no coherent light source is required. This avoids the stability, sensitivity and cost limitations of conventional laser-based interferometry. Since conoscopic optical systems use concentric optics they are insensitive to the position of the key optical components. The scale of measurement can simply be altered by changing the objective lens – allowing users to purchase one system with different lenses for applications ranging from sub-microns to metres.

The Conoscan maintains high precision and repeatability over a wide working range. In most cases the precision and repeatability is better than 1/1800th of the working range.

The technology is available as a complete measurement station (the Conoscan); the measurement probe is also sold singly for integration into existing measuring systems.
