For years, the lidar industry has been locked in a fierce contest to build sensors small enough, cheap enough, and reliable enough to earn a permanent place on mass-market automobiles. Spinning mechanical units perched atop self-driving prototypes made for striking visuals, but automakers made clear they would never bolt such contraptions onto consumer vehicles. Now, a Redmond, Washington–based company called MicroVision believes it has cracked the problem with a solid-state lidar sensor built around a single microelectromechanical systems (MEMS) mirror—and the automotive world is starting to pay attention.
As reported by IEEE Spectrum, MicroVision’s latest sensor, dubbed MOVIA L, relies on a lone MEMS mirror roughly the size of a pencil eraser to steer laser beams across a wide field of view. The device has no rotating parts, no bulky optical assemblies, and no polygon mirrors. It is, in engineering terms, a solid-state system—though purists may quibble, since the mirror itself physically tilts. The distinction matters because eliminating large moving components dramatically improves durability, shrinks the package, and drives down manufacturing costs, all prerequisites for integration into advanced driver-assistance systems (ADAS) headed for high-volume production lines.
Why Solid-State Lidar Matters for the Next Generation of ADAS
The push toward solid-state lidar is not merely an academic exercise. Traditional mechanical lidar sensors, exemplified by the rooftop spinners on early Waymo vehicles, can cost thousands of dollars per unit and have limited lifespans due to bearing wear and optical alignment drift. Automakers planning to embed lidar into front fascias, rooflines, and headlamp housings need sensors that survive the punishing vibration, temperature swings, and humidity of real-world driving for a decade or more. Solid-state architectures promise exactly that, and the race to deliver them has attracted billions of dollars in venture capital and public-market investment over the past five years.
MicroVision’s approach, according to the IEEE Spectrum report, centers on a single MEMS mirror that oscillates at high speed to paint the scene with 905-nanometer laser pulses. The reflected light is captured by an array of single-photon avalanche diodes (SPADs), which are sensitive enough to detect individual photons bouncing back from objects more than 200 meters away. The company claims the MOVIA L sensor achieves a 120-degree horizontal field of view and a vertical field of view sufficient for highway and urban driving scenarios—specifications that, if validated in production, would place it among the most capable solid-state units on the market.
MEMS Mirrors: An Old Technology Finds a New Calling
MEMS mirrors are not new. Texas Instruments popularized them decades ago inside digital light processing (DLP) projectors, where arrays of tiny mirrors redirect light to form images on screens. MicroVision itself spent years developing MEMS-based pico projectors before pivoting toward automotive lidar. The intellectual property and manufacturing know-how accumulated during that earlier chapter now form the backbone of its lidar program. The company’s mirror is fabricated using standard semiconductor processes, which means it can theoretically be produced in high volumes at costs that track the familiar learning curves of the chip industry.
The single-mirror design also simplifies the optical path. Competing solid-state approaches—such as optical phased arrays championed by Analog Photonics and others, or flash lidar systems that illuminate an entire scene at once—face their own engineering trade-offs. Optical phased arrays struggle with limited range and high power consumption. Flash lidar systems require extremely powerful lasers to illuminate distant objects across a wide field, raising eye-safety concerns and thermal management challenges. MicroVision’s scanning architecture sidesteps some of these issues by concentrating laser energy on a narrow spot at any given instant, improving signal-to-noise ratio at range while keeping average power modest.
The SPAD Detector Advantage
Equally important is the detector side of the equation. Single-photon avalanche diodes have emerged as a favored receiver technology across the lidar industry because of their extraordinary sensitivity. Each SPAD pixel can register the arrival of a single photon and timestamp it with sub-nanosecond precision, enabling accurate range measurements even when very little light returns from distant or dark-colored objects. Sony, which supplies SPAD arrays to several lidar makers, has invested heavily in scaling production. MicroVision’s use of SPAD receivers aligns with a broader industry trend toward photon-counting detection, which multiple analysts expect to become the default approach for automotive lidar within the next few years.
The combination of a MEMS transmitter and a SPAD receiver in a compact, solid-state package is what MicroVision is banking on to win design slots with major automakers. According to IEEE Spectrum, the company has been working with unnamed OEM partners to validate the MOVIA L sensor for series production, with initial deployments expected to target Level 2+ and Level 3 ADAS applications—systems that can handle highway driving under certain conditions but still require a human driver as a fallback.
A Crowded Field With High Stakes
MicroVision is far from alone in pursuing solid-state lidar for ADAS. Luminar Technologies has secured a production contract with Volvo and counts Mercedes-Benz and Polestar among its partners. Hesai Technology, a Shanghai-based manufacturer, has shipped hundreds of thousands of lidar units, many of them semi-solid-state designs using hybrid scanning mechanisms. Innoviz Technologies supplies BMW. Cepton, now a subsidiary of Koito Manufacturing, has a deal with General Motors. Each company touts different technical advantages—wavelength choices, scanning methods, detector types, and integration strategies vary widely.
What distinguishes MicroVision’s pitch, at least on paper, is the radical simplicity of a single MEMS mirror doing all the beam steering. Fewer components generally mean fewer failure modes, lower assembly costs, and a smaller form factor. The company has publicly stated that its bill of materials targets are designed to hit price points compatible with vehicles selling in the $30,000-to-$50,000 range, a segment where every dollar of sensor cost is scrutinized relentlessly by procurement teams. Whether MicroVision can deliver on those targets at scale remains an open question—one that investors, who have watched the company’s stock gyrate wildly over the past several years, are monitoring closely.
Regulatory Tailwinds and the Road to Level 3
The timing of MicroVision’s push coincides with regulatory developments that could accelerate lidar adoption. The European Union’s General Safety Regulation, which took full effect for new vehicle type approvals in July 2024, mandates advanced safety features including intelligent speed assistance and emergency lane-keeping systems. While lidar is not explicitly required, automakers developing Level 3 highway pilots—systems where the car assumes legal responsibility for driving—view lidar as an essential sensor for achieving the redundancy and reliability that regulators demand. Mercedes-Benz’s Drive Pilot system, currently the only SAE Level 3 system certified for use on public roads in parts of Europe and certain U.S. states, relies on a lidar sensor from Valeo.
In the United States, the National Highway Traffic Safety Administration has signaled growing interest in performance-based standards for automated driving systems, which could further incentivize the adoption of high-resolution perception sensors. China, meanwhile, has become the world’s largest market for lidar-equipped passenger vehicles, with domestic brands like Li Auto, NIO, and XPeng integrating lidar units from Hesai, RoboSense, and others as standard equipment on models priced well below luxury thresholds. The competitive pressure from Chinese automakers is pushing Western OEMs to accelerate their own lidar integration timelines.
Manufacturing Scale: The Make-or-Break Challenge
For MicroVision and its peers, the critical hurdle is no longer just technical performance—it is manufacturing at automotive scale. Producing millions of lidar sensors per year with the consistency, yield rates, and cost structures that automakers expect requires partnerships with established semiconductor foundries and tier-one automotive suppliers. MicroVision has indicated it is working with contract manufacturers experienced in MEMS fabrication, but the company has not publicly named its production partners for the MOVIA L sensor.
Industry veterans recall the cautionary tale of Velodyne Lidar, once the dominant name in the sector, which struggled to transition from low-volume, high-cost production to the mass-market model automakers demanded. Velodyne was eventually acquired by Ouster in 2023, and the combined entity continues to compete primarily in industrial and robotics markets rather than passenger automotive. The lesson was clear: technical prowess alone does not guarantee commercial success in the automotive supply chain, where relationships, quality systems, and production discipline matter as much as sensor specifications.
What Comes Next for MicroVision and the Lidar Industry
MicroVision’s stock, traded on the Nasdaq under the ticker MVIS, remains a favorite among retail investors who have followed the company through multiple technology pivots over its three-decade history. The company reported cash reserves that it has said should fund operations through key milestones, but like most lidar pure-plays, it is not yet profitable. Revenue generation hinges on converting OEM interest into binding production contracts—a process that typically takes years in the automotive world, given the long validation and qualification cycles involved.
The broader lidar industry stands at an inflection point. After years of hype, followed by a painful correction that wiped out billions in market capitalization across the sector in 2022 and 2023, the surviving companies are now competing for a finite number of production programs. Consolidation is widely expected to continue, with only a handful of lidar makers likely to emerge as long-term suppliers to global automakers. MicroVision’s single-MEMS-mirror approach represents a compelling engineering thesis—compact, potentially inexpensive, and built on proven semiconductor manufacturing techniques. Whether that thesis translates into cars rolling off assembly lines with MOVIA L sensors behind their bumpers will determine whether MicroVision becomes a footnote or a fixture in the automotive supply chain of the 2030s.
