New Alicona InfiniteFocus Portable

As the Australian and New Zealand distributor for the complete range of imaging products from leading Austrian-producer Alicona Imaging GmbH, Hi-Tech Metrology is pleased to announce the release of a new portable infinite focus measurement system - the IF-Portable.

Using the principle of focus variation the Infinite Focus Portable is a robust and mobile optical system to measure both the form and roughness of larger surfaces. It can be used by semi-skilled personnel in production areas to measure both flat and curved surfaces with just one of its key applications being inspection of industrial print rollers.


According to Andreas Tillmann, project manager with leading German print roller producer - Heidelberger Druck..."The form of the laser structured surface geometry is one of the crucial challenges when it comes to measure the roller platens. With the IF-Portable system we have found a solution which really delivers precise results."

The system can be used in all areas of production with a wide range of materials composites.  Focus-Variation technology delivers high resolution, stable and repeatable results even in production environments and when measuring surfaces with steep flank angles and strongly varying reflection properties.

Amongst other applications, the Alicona IF-Portable is used for the measurement of turbine blades, rotor blades, and steel surfaces in the oil and gas and mining sectors - particularly in the study of corrosion mechanics, and tribology as well as other analysis and research projects.

One of its significant advantages is the ability to quickly and accurately change objectives on the instrument.  This enhances measurement accuracy as errors from adjustment and time consuming recalibration after an objective change becomes obsolete. The extremely large vertical scanning range enables the measurement of various surface types and sizes. In contrast to other techniques, Focus-Variation also provides color information registered to the 3D data. This enables additional applications and new possibilities in research and development to be considered for this equipment.


The IF-Portable is based on the method of focus-variation. The optical technology provides a point density of up to 100 million measurement points which allows the surface measurement of large spot sizes and measuring volumes. The uncertainty of measurement associated with each measurement is automatically calculated and displayed.

Focus-Variation technology from Alicona with the new IF-Portable system provides the following benefits:

  • Results with a vertical resolution of 10nm are achievable - even at large measurement volumes
  • Robust, stable and repeatable measurements are provided, including applications where steep flank angles and surfaces and strongly varying reflection properties cause problems with other technologies
  • Measurements of small angles and radii are easily achieved
  • Large vertical scan range enables the measurement of various geometry types and forms
  • All measurements include an estimated measurement uncertainty
  • Surface topography information is captured with registered colour information, which provides higher accuracy - particularly with large measurement fields
  • Easy to achieve automation options via scripting
  • Reliable measurements even in production environments as the system is vibration-resistant, and able to cope with temperature variation and extraneous light conditions.
