Why GelSight® Modulus™ Is A New Chapter in Surface Metrology
Surface metrology, the science of measuring and analyzing surface topography and properties, is essential to advanced manufacturing. From aerospace to automotive to electronics, it ensures product quality, safety, and performance by revealing the smallest variations that can make or break reliability. Yet, traditional surface metrology tools come with significant limitations. They are often confined to lab settings, require destructive testing, depend heavily on operator skill, or are restricted to a single type of measurement. These barriers slow down innovation and decision-making.
GelSight® Modulus™ changes that equation.
By combining high-resolution tactile imaging with mobile, non-destructive measurement of mechanical properties, it rewrites the playbook of surface metrology. Manufacturers can now capture deeper insights, faster, without the compromises of antiquated processes.
How Conventional Surface Metrology Is Holding You Back
To understand why GelSight® Modulus™ represents a true step forward, it helps to look at the limitations that have long constrained conventional surface metrology.
Incomplete Context
Many existing systems can only measure surface roughness or topography, providing an incomplete picture. Without insights into key mechanical properties, manufacturers lack the full context needed to ensure material performance and reliability.
Costly and Time-Consuming
In other cases, destructive methods are required to test critical components. These approaches are not only costly and time-consuming, but also impractical for parts that are difficult to replace or for components with limited access where traditional tools simply can’t reach.
Accessibility
Accessibility presents another challenge. Bulky instruments are often restricted to labs, unable to measure surfaces with complex geometries or be deployed directly on the shop floor. In some instances, these tools are too large even for standard laboratory environments.
Poor Digital Integration
Conventional metrology methods also fall short in digital integration. They cannot easily capture or store surface data for long-term reference. Modulus, on the other hand, allows users to digitally map and archive surface data, supporting record-keeping for the entire lifetime of a part.
Silos and Bottlenecks
Finally, results from traditional systems are often siloed, with slow reporting cycles that create bottlenecks. This delays decision-making and prevents teams from responding quickly to issues on the production line.
What Makes GelSight® Modulus™ Different From Conventional Metrology Tools?
Traditional surface metrology relies on bulky, single-purpose instruments that are often destructive, slow, and limited in scope. Modulus replaces those outdated methods with a portable, non-destructive platform that captures both surface texture and mechanical properties in real time. The result is faster insights, broader accessibility, and a clear step forward in surface metrology.
A Single Portable Device for Imaging and Mechanical Testing
Modulus breaks from convention by combining high-resolution tactile imaging with surface testing in a single, portable device. Instead of relying on multiple instruments (one for roughness, another for hardness, etc), manufacturers gain an all-in-one tool that dramatically simplifies workflows. This integration reduces the need for destructive testing and eliminates the complexity of stitching together results from different systems.
Lab-Level Precision for Texture and Elastic Modulus
With GelSight® Modulus™, manufacturers no longer need to choose between accuracy and convenience. The system captures both fine surface texture and elastic modulus with the precision of lab-based instruments, enabling a more complete understanding of material behavior. This dual capability supports advanced quality control, ensuring that even subtle variations in stiffness or surface finish are identified before they can compromise performance.
Non-Destructive Measurements, Anywhere
One of the most powerful advantages of Modulus is mobility. The device delivers non-destructive measurements that can be performed in the lab, on the production floor, or even in the field — wherever insights are needed most. This flexibility means manufacturers can resolve issues in real time, rather than waiting for samples to be sent to a lab and tested days later. The result is faster decision-making and greater efficiency across the entire manufacturing process.
Accessibility and a Platform for the Future
Modulus also overcomes the accessibility barriers of traditional instruments. Its compact design allows direct measurement of surfaces that were previously out of reach, whether due to geometry, location, or size constraints. Beyond this, Modulus is not just a tool but an advancing technology platform. With ongoing software and hardware updates, its capabilities will continue to expand, giving manufacturers a future-proof solution for the evolving demands of surface metrology.
Swappable Lenses
Modulus features an interchangeable lens design that lets inspectors switch seamlessly between straight and 90-degree lenses on the same sensor body. This modular flexibility allows a single device to handle a wide variety of part geometries and access challenges. There is no need for multiple dedicated tools. In the field, operators can quickly swap configurations, moving from inspecting tight-clearance areas with the straight lens to evaluating bore walls with the 90-degree lens. Each lens is serialized, and the software automatically recognizes it, loading the correct gel calibration from the last use.
The result is faster workflows and consistent, reliable measurement performance across diverse applications.
Access to Inner Diameters
Modulus makes it possible to capture high-resolution 3D surface data from hard-to-reach areas such as bores, tubes, and cavities. By enabling non-destructive inspection of inner diameters, it eliminates the need for replica molds or disassembly. This expanded accessibility helps manufacturers evaluate critical internal surfaces with confidence while reducing downtime in both production and maintenance environments.
A New Chapter in Surface Metrology
Modulus represents more than just an incremental improvement. It’s a fundamental shift in how surface data is captured, analyzed, and applied. Rather than making small upgrades to existing tools, it redefines the process altogether by combining multiple measurement capabilities in a portable, non-destructive system. This leap forward gives manufacturers not only richer insights, but also the agility to act on them faster than ever before.
Multi-Dimensional Insight
With GelSight® Modulus™, manufacturers gain a complete picture of material behavior by capturing both surface roughness and stiffness in a single workflow. Instead of switching between different instruments or sacrificing one type of measurement for another, teams can now evaluate texture and elastic modulus side by side. This multi-dimensional insight enables faster, more confident decisions, helping ensure that every component meets the highest standards of quality and performance.
Mobile Metrology
Modulus takes precision surface metrology out of the lab and directly to the part. Instead of halting production to send components away for testing, manufacturers can now bring the instrument to the shop floor, or even into the field, to capture high-quality measurements in real time. Its compact size and flexible reach make it ideal for working with complex geometries or hard-to-access areas where conventional tools fall short. Designed with modularity in mind, Modulus adapts to evolving needs, ensuring manufacturers have the flexibility to meet today’s challenges while preparing for tomorrow’s demands.
