We focus on measurement so you can focus on its application

Digital Metrology is committed to the development and deployment of measurement technologies. We provide innovative software, custom-tailored metrology systems, consultation and training – while never losing sight of the fact that metrology is “a means to an end.” The value of a measurement isn’t in the result – it’s in what you do with it. Digital Metrology brings understanding beyond measure, helping you develop, interpret and apply your measurement results to your specific situation.

New “Average Roughness (Ra)” Notepad Series Video

The average roughness (or “Ra”) value of a surface is the most common number describing the “amount” of roughness on that surface. While the Ra value (or “Sa” for areal / 3D measurements) may give a general sense of the surface texture, it cannot distinguish between two surfaces of different shapes. For example, a jagged surface with sharp spikes could have the same Ra value as a smoothly plateaued surface with lots of deep porosity. As we show in this video, describing a surface using only Ra is like describing a concert only by loudness! Yet, Ra (or Sa) may still have its uses in some production settings.

New Paper: Defining and Describing Surface Error

Controlling optical component performance requires well-defined measurement processes. In this white paper we look at how analysis software can help standardize measurement processes and results, by guiding users through the steps of the measurement process (geometry fitting, filtering, and defining parameters) and by making it simple to visualize the impact of analysis options.

“Bandpass Waviness” Notepad Series Video

In our last video, "Roughness and Waviness," we looked at how to separate longer wavelength "waviness" from short-wavelength "roughness." In "Bandpass Waviness" we go a step further and also separate waviness from the long-wavelength "form" shapes. Making this distinction lets us target the waviness features that could matter most to you. For example, if you are trying to create a sealing surface, controlling the waviness-related lumps or bumps may be your biggest challenge. One surprising upshot of controlling these features separately: the added controls may actually let you loosen tolerances on the long wavelength form as a result.

Read the Latest Edition of our ‘Surface Matters’ Newsletter

In the June edition we show you how to use a penny to compare the capabilities of measurement systems. We look at the relative size of high-resolution areal (3D) measurements versus typical profile (2D) traces (you may be surprised). We also talk about how custom solutions can outperform off-the-shelf options for many production tasks. And, we introduce you to some new productivity tools in our OmniSurf3D software that may make your job easier.

Read our “Advanced Wear Analysis” article in Metrology News

Accurately assessing wear is critical for designing surfaces in contact. Unfortunately, mistakes are common when it comes to assessing actual wear depth. This article presents fundamentals and practical tools for exploring and assessing surfaces at various stages of wear.  You can read our article on advanced wear assessment in Metrology News, Sept. 23, 2019.

See our “Predicting Surface Functions” article in AM&D Magazine

For surface texture measurements to be most effective, results must predict functionality. Morphological filters allow us to quantify functions such as appearance, sealing ability, and wear resistance. Read our article on this topic that appeared in Aerospace Manufacturing and Design Magazine, July 2019.
