FREE-TO-ATTEND Workshop on Topography Measurement

using Infinite Focus co-hosted by The University of Northumbria

Wednesday, 26th April, 2017

To help those using, or planning to use non-contact optical methods for surface inspection, Alicona UK is holding again by popular demand a Non-Contact Topography Measurement Workshop at The University of Northumbria on Wednesday, 26th April, 2017.

The day will give an introduction into non-contact measurements using Focus Variation Measurement Technology. The event will be ideal for those both in industry and research who need to measure and understand surface through measurement.


We anticipate high interest in the event, so with limited spaces available, would strongly recommend early booking to attend.

Pre-registration can be made by e-mailing your name, company/organisation affiliation, address and a contact number to If would have liked to attend but are unavailable on the date, please advise us so that we can either try to book you into a future event or contact you to discuss the technology directly.

The workshop will cover a number of technologies, including Contact Metrology Theory, Optical Measurement Methods and Sources of Error, plus on show the optical 3D measurement system InfiniteFocusSL. 

The event will be supported by experienced metrologists and equipment to allow attendees to bring samples to see and experience the relative performances and advantages of the Alicona surface measurement method.
The event will be held in the The University of Northumbria, kindly hosted by Dr Islam Shyha. Registration/refreshments is from 13:00 pm, for a 13:30 pm start, finishing late afternoon.

After the welcoming introduction by the Professor Glen McHale, Pro Vice-Chancellor for Faculty of Engineering and Environment, topics covered will include:

  • Why non-contact topography can give advantages during surface measurement
  • A brief overview of the different technologies available
  • Theory of Stylus, Laser, Scanning Confocal Gauges, White Light Interferometry and Focus Variation
  • Single point, area mapping, full-field area and ultra-high resolution measurements
  • Sources of measurement error
  • Details of instruments utilising the technologies
  • Application examples and ideas

Supporting the talks will be the following instrument: Alicona InfiniteFocusSL

PARKING: We have some free limited car parking places (10) available. We will need to get the name and car registration, these will be offered on a first come first served basis.
