When people talk about AI, they usually talk about GPUs, semiconductor fabs or the latest large language model. Few think about the laser optics that make many of those technologies possible.
Behind every wafer inspection system, precision micromachining platform, or ultrafast laser, there is an optical system expected to perform flawlessly, often under enormous power densities and with tolerances measured in nanometres.
Huyen Vu, CEO of OPTOMAN, has spent much of his career working on this less visible layer of high-tech industry: the optical components that allow advanced laser systems to operate with extreme precision.

Subscribe“The optics are not always the part people talk about first,” Vu says. “But when they fail, the whole system feels it.”
Founded in Vilnius, Lithuania, in 2017, OPTOMAN designs and manufactures custom ion beam sputtered (IBS) laser optics for high-power, ultrafast, industrial, scientific, aerospace, defense, and medical applications. As laser systems continue to push the limits of power, precision and reliability, the demands placed on optical coatings have grown just as quickly.
Building for the Hardest Laser Problems
High-power laser optics rarely fail because the reflectivity curve looked wrong on a datasheet.
More often, problems appear only after the optic has been integrated into the system, when thermal load, pulse duration, beam profile, or environmental conditions expose limitations that weren’t obvious during qualification. That’s why most customers don’t come to OPTOMAN looking for a catalog component.
“They’re usually pushing the limits of an existing system,” says Vu. “Higher average power. Shorter pulses. Longer lifetime. Better stability. Every project starts with a different engineering challenge.”
Rather than adapting existing products, the team develops coatings around the application itself. Every design begins with the operating conditions: wavelength, angle of incidence, pulse duration, fluence, substrate material, environmental requirements, and expected lifetime.
Those parameters ultimately determine everything from coating architecture to deposition strategy.
Why Coating Became the Edge
At the center of OPTOMAN’s work is Ion Beam Sputtering, often called IBS. For outsiders, it can sound like a narrow technical process. For high-power laser systems, it can be the difference between performance and failure.
Ion Beam Sputtering has become the foundation of OPTOMAN’s manufacturing because of the dense, low-defect thin films it produces. For demanding laser applications, that translates into lower absorption, excellent environmental stability, and highly repeatable optical performance.
Those characteristics become increasingly important as laser systems continue to scale in both average power and pulse energy, where even extremely small optical losses can generate unwanted heat or gradually reduce long-term performance.
The Hidden Link to Semiconductors and AI
The AI boom has transformed semiconductor manufacturing into one of the world’s most closely watched industries.
Behind every advanced chip, however, sits an enormous manufacturing ecosystem built around precision optics, laser processing, metrology and inspection.
“AI depends on far more than computing power,” says Vu. “Before a processor ever reaches a data center, it has already passed through some of the most precise manufacturing systems ever built.”
That broader ecosystem is where OPTOMAN contributes. Its components are used in applications ranging from semiconductor processing and photolithography to scientific instrumentation, aerospace, defense and medical laser systems — industries where optical performance directly influences system accuracy and reliability.
A Lithuanian Company with Global Ambitions
Lithuania has earned a global reputation for photonics innovation, making it a natural home for a company focused on advanced laser optics.
Since its founding, OPTOMAN has expanded from a specialized manufacturer of coatings and optical components into an international supplier serving customers across Europe, North America, and Asia.
That growth reached another milestone in 2026 with the opening of OPTOMAN Inc. in Folsom, California.
“The U.S. is one of the most dynamic markets for advanced laser technology,” says Vu. “Having a local team allows us to collaborate more closely with customers while providing direct access to the same engineering expertise and manufacturing capabilities we’ve built in Lithuania.”
Rather than changing the company’s technical focus, the expansion brings OPTOMAN’s engineering support closer to the customers developing next-generation laser systems.
Making Premium Optics Easier to Access
One theme appears repeatedly in conversations with OPTOMAN’s engineers.
Projects rarely begin with a request for a standard mirror or beamsplitter. Instead, they begin with questions.
- How can absorption be reduced?
- Can coating lifetime be extended?
- How can thermal effects be minimized without compromising spectral performance?
“The earlier we’re involved,” Vu says, “the more opportunity we have to optimize the solution around the application instead of simply manufacturing to a drawing.”
That collaborative approach has become a defining part of the company’s engineering process, helping customers move efficiently from research and prototyping into serial production.
Quality as a Business Strategy
In high-power laser systems, consistency is every bit as important as performance.
A coating that performs exceptionally well once but cannot be reproduced reliably offers little value in production.
For that reason, OPTOMAN places equal emphasis on process control, repeatability, and traceability.
“Customers need confidence that the hundredth optic performs just like the first,” says Vu. “That’s what enables them to build reliable systems.”
The company’s ISO 9001 certification and JOSCAR registration support that commitment, providing customers with structured quality management alongside technical expertise developed through years of coating optimization.
Where OPTOMAN Is Now
As semiconductor manufacturing, quantum technologies, space systems and high-power lasers continue to evolve, the performance requirements placed on optical coatings will only become more demanding.
For OPTOMAN, that trend reinforces the same direction the company has followed since its founding: specializing in applications where precision, reliability and long-term stability matter most.
“The biggest technological breakthroughs are often supported by countless engineering decisions that happen behind the scenes,” says Vu. “Our role is to make sure the optical components enabling those breakthroughs perform exactly as they’re expected to.”
It’s a role that rarely attracts headlines—but increasingly, it’s one that advanced technology depends on.
That is the position OPTOMAN has chosen. Not the loudest part of the system. Not the most obvious. But one of the parts that has to perform when everything else depends on it. OPTOMAN is building the precision layer behind advanced technology.
