GelSight

Non-destructive 3D surface imaging for QA

Overview

GelSight develops portable, non-destructive 3D imaging tools for quality control in high-value manufacturing such as aerospace and automotive. The systems use an elastomeric sensor to capture detailed 3D surface topography, allowing quick visualization and precise measurement of surfaces like metal, glass, and carbon fiber. The data can be collected in the field or on the factory floor, helping expensive parts move through production faster and creating an audit trail for later reference. The products are sold directly to industries where surface quality matters, with service contracts for maintenance and calibration as a potential offering.

Simplify's take

What believers are saying

  • GelSight Mobile 4.5 launched November 3, 2026, improving measurement tools, performance, and reporting.
  • TIME named Modulus a Best Invention of 2026, boosting buyer credibility.
  • Air Force SBIR Phase II on March 10, 2026 expands defense robotics revenue.

What critics are saying

  • GelSight still has only 100 Modulus units sold, limiting scale versus larger metrology vendors.
  • Defense and automotive concentration ties growth to procurement cycles and factory capex timing.
  • If Modulus adoption stalls, portable tactile sensing stays niche and funding needs tighten.

What makes GelSight unique

  • Modulus measures bores and confined geometries with swappable lenses, unlike conventional surface tools.
  • MIT-born gel tactile sensing delivers micron-level topography on metals, glass, composites, and interiors.
  • Remote Assist turns inspection into networked collaboration, letting engineers trigger scans remotely.

GelSight Modulus named to TIME's Best Inventions of 2026 and Fast Company's Next Big Things in Tech.

GelSight Modulus named to TIME's Best Inventions of 2026 and Fast Company's Next Big Things in Tech. * Business Wire * Oct 20, 2026 WALTHAM, Mass.-(BUSINESS WIRE)-Oct 20, 2026- GelSight(R), a pioneer in surface analysis technology, today announced that its Modulus(TM) surface measurement system has been named to TIME's list of the Best Inventions of 2026. The honor follows Modulus's selection as a Fast Company 2026 Next Big Things in Tech honoree in the Robotics & Automation category, announced on October 6. GelSight's Modulus(TM) surface measurement system has been named to TIME's list of the Best Inventions of 2026. The honor follows Modulus's selection as a Fast Company 2026 Next Big Things in Tech honoree. Since launching in July 2025, Modulus has been adopted by teams in aerospace, defense, automotive, and advanced manufacturing across North America and Europe. Customers include the U.S. Department of Defense and Rolls-Royce. Modulus delivers micron-level surface measurements in places conventional tools cannot reach, such as the inside of bores, tubes, and engine components. Built on gel-based tactile sensing that originated at MIT, it is designed like an advanced DSLR camera system, so inspectors can hot-swap lenses and cameras in the field. That lets one device handle a wide range of inspections without disassembly, surface replicas, or destructive testing. Modulus was initially developed with the U.S. Army's DEVCOM Aviation & Missile Center and maintainers at Corpus Christi Army Depot to address rotorcraft inspection challenges. "The hardest places to measure are often the most critical ones," said Youssef Benmokhtar, CEO of GelSight. "Being recognized by TIME and Fast Company is a credit to the engineers who built Modulus and to the customers who trusted it early and pushed us to keep improving it." That improvement continued in May 2026, when GelSight introduced High Resolution lenses and GelSight Mobile(TM) 4.4 software. They bring lab-grade roughness measurement to the shop floor and can be added to existing Modulus devices with a lens swap. Last week, TIME revealed its annual list of the Best Inventions, which features 300 extraordinary innovations changing our lives. To compile the list, TIME solicited nominations from its editors and correspondents around the world, and through an online application process, paying special attention to growing fields such as health care and AI. TIME then evaluated each contender on key factors including originality, efficacy, ambition, and impact. See the full list at ti.me/best-inventions. Fast Company's Next Big Things in Tech awards highlight technology breakthroughs the magazine expects to have a positive impact on consumers, businesses, or society over the next five years. Fast Company recognized GelSight for taking machine sensing into the realm of touch.

GelSight launches Remote Assist to enable live Remote surface metrology.

GelSight launches Remote Assist to enable live Remote surface metrology. GelSight, a pioneer in surface analysis technology, has announced the release of GelSight Remote Assist, a new standalone application that lets additional users on the same network view the GelSight live view in real time and trigger scans remotely. Built on the GelSight API, Remote Assist connects the person at the part with the person who needs to make the decision, no matter where they sit in the facility. GelSight is used daily for challenging in-situ measurements, from inside fuel tanks to mezzanines accessing large structural components, environments where the person best positioned to operate the sensor and the person who needs to make the engineering decision are rarely in the same place. Remote Assist closes that gap. An engineer at a desk can now see exactly what the sensor sees, live, and trigger the scan the moment it's positioned correctly, while the inspector is still at the part. The result: no more capturing data, walking it back, and waiting for review, and no more repeat trips because the first scan missed the area of interest. The inspection and the engineering decision can happen in the same moment. Key capabilities of GelSight Remote Assist include: Remote Live View: Watch the GelSight sensor feed in real time from any machine on the same network. Remote Scan Triggering: Capture scans from the reviewing station the instant the sensor is in position. Real-Time Collaboration: Inspector and engineer work the same inspection together, eliminating handoffs and rework. Standalone Application: Installs alongside your existing GelSight setup on any Windows computer, with no changes to your current workflow. "Your engineering experts can't be everywhere. Now they don't have to be," said Youssef Benmokhtar, CEO of GelSight. "We believe Remote Assist is the first capability of its kind in the surface metrology and inspection space, extending GelSight's Any Material, Anywhere promise so that expertise no longer has to travel with the sensor."

GelSight launches Remote Assist for real-time collaborative surface inspection across facilities

GelSight, a surface analysis technology company, has launched Remote Assist, a standalone application enabling real-time remote collaboration for in-situ inspections. The software allows multiple users on the same network to view live sensor feeds and trigger scans remotely. Remote Assist addresses challenges in industrial inspection environments where operators and decision-makers work in different locations. Engineers can now view sensor data in real time from their desks and capture scans whilst inspectors remain at the inspection site, eliminating delays from data handoffs and reducing repeat visits. The application installs on Windows computers alongside existing GelSight systems. CEO Youssef Benmokhtar described it as the first capability of its kind in surface metrology and inspection. GelSight's technology, developed at MIT, is used across aerospace, automotive, forensics, and robotics sectors.

GelSight launches high-resolution Modulus lenses for lab-grade surface roughness measurement

GelSight has launched its High Resolution lens family for the Modulus platform, comprising two 20mm optical lenses: the L2000HR (straight) and L2090HR (90-degree). The new lenses work with existing Modulus camera bodies, bringing laboratory-grade surface and profile roughness measurement to production floors through a simple lens swap. The HR lenses feature redesigned optical, illumination and gel architecture, achieving surface roughness resolution of 0.2μm-10μm. They support industry-standard profile roughness parameters and advanced 3D areal texture metrics, transforming GelSight from defect detection into a portable, quantitative surface analysis platform. The 90-degree variant enables measurement in confined geometries like bores and inside diameters. The launch coincides with GelSight Mobile 4.4 software release, which adds full roughness parameter support and workflow improvements. Both lenses are available now.
