Welcome to

Surfract provides software and services for analyzing surface texture, or roughness, to support quality control, product and process design, and research.

Sfrax 1.0 Now Available

sfraxSfrax 1.0 has been officially released. To download the latest version or register for a Trial copy go to

New features include built in statistical differentiation and correlation as well as support for many more different analyses including:

  • Area-scale, Length-scale Fractal Analyses
  • Peak-to-Peak and Filling (2D / 3D) Analyses
  • Length Scale Anisotropy, Digs and Scratches (Experimental)

In addition Sfrax provides an extensible interface that allows for additional analyses to be made available from both Surfract and third-parties.

For more information or to pre-order Sfrax please see our Products and Purchasing pages.

Surfract Featured in Nature Magazine

Recently featured in a paper in Nature magazine (Dental microwear texture analysis shows within species diet variability in fossil hominins), we have developed a simple user interface (Toothfrax) to allow anyone to perform the analyses described in that paper.

Kfrax Analyis System and DLL's now Available

As of August 4, 2005 the Kfrax Analysis System and Kfrax DLL's are now available. For more details on this release please see our products page.

Supporting the latest ASME B46 fractal standard, Surfract's software package, KFrax, provides a variety of surface analysis algorithms including a patented Area-scale analysis.

In addition, Surfract provides consulting services including:

  • Analysis
  • Custom Development
  • Research
  • Education

With a breadth of applications across many industries, Surfract's specialized fractal analysis has been used in analysis of many different surfaces including:

  • Chocolate
  • Teeth
  • Skis

In collaboration with the WPI Surface Metrology Lab, Surfract has participated in groundbreaking research. With Christopher A. Brown, Ph.D., PE, Surfract has over sixteen years of experience applying specialized, scale-sensitive fractal analyses to measured surfaces and profiles. We invented and patented area-scale analysis for surface texture, and we have experience with many types of surfaces and applications from runways to skin, contact lenses and hard disks.

Our specialized analyses can relate surface texture to product performance, manufacturing processes, and surface behavior where conventional analysis cannot.
