Optonas, one of Northern and Eastern Europe’s largest coated optics manufacturers, details its expansion into turnkey optomechanical assemblies and high-durability infrared (IR) optical coatings. Operating 13 coating chambers across Ion Beam Sputtering (IBS), Electron Beam Evaporation (EBE), and Ion Assisted Deposition (IAD) technologies, the Vilnius-based company supports demanding defense, space, industrial, and medical laser applications. Optonas highlights its specialized IR coating process that achieves broadband transmission levels exceeding 95–98% while maintaining “Severe” abrasion resistance verified under directional LED illumination. By offering integrated optomechanical design, substrate coatings, and in-house environmental, shock, and vibration qualification, Optonas delivers plug-and-play optical subassemblies for global system integrators.
A brief description of the company and its activities.
Optonas is a Lithuania-based manufacturer of high-performance precision optics and optical coatings, headquartered in Vilnius. The company is recognized as one of the largest coated optics manufacturers in Northern and Eastern Europe, operating thirteen coating chambers utilizing IBS (Ion Beam Sputtering), EBE (Electron Beam Evaporation), and EBE+IAD (Ion Assisted Deposition) technologies. Optonas supplies advanced optical solutions to customers worldwide, serving demanding applications in defense, space, industrial, medical laser systems, and imaging technologies.
What are the main areas of activity of the company?
Optonas focuses on three key areas:
- High-performance optical coatings for ultraviolet, visible, infrared, and laser applications.
- Manufacturing of precision optical components for laser and imaging systems, by outsourcing optical substrates to trusted partners and implementing high-performance coatings, with necessary inspections and testing.
- Optomechanical assemblies, including design, integration, testing, and qualification.
The company also provides environmental, shock, and vibration testing, helping customers obtain fully traceable and application-ready optical assemblies.
What’s the news about new products/services?
A major recent development is the expansion of Optonas’ offerings from coated optics to complete optomechanical assemblies. Customers can now receive integrated optical and mechanical solutions along with environmental qualification services. This enables a “plug-and-play” approach for system integrators and prime contractors, reducing complexity in their supply chains.
The company has also strengthened its position in high-durability infrared optics, delivering solutions that combine exceptional spectral performance with MIL-standard durability requirements for defense and aerospace applications.
What are the ranges of products/services?
Optonas offers:
- High-performance optical components for laser, imaging, infrared, and electro-optical systems
- Mission-specific optical coating solutions from DUV to FIR, including advanced dielectric, metallic, and hybrid designs
- Optical and optomechanical assemblies for demanding aerospace, defense, and space applications
- Electro-optical, imaging, and laser system subassemblies
- Ruggedized optical systems qualified for shock, vibration, and environmental performance requirements
- Optical testing, metrology, environmental qualification, and compliance verification
- Design-for-manufacturing and engineering support from concept development through production readiness
- Scalable manufacturing from R&D prototypes to series production
- Solutions supporting missions across land, sea, air, and space domains
What is the state of the market where you are currently active?
The markets served by Optonas remain very strong, particularly in defense, aerospace, and advanced sensing applications. Growing investments in security, surveillance, infrared imaging, and directed-energy technologies are driving significant demand for high-performance optics. Demand for durable infrared optics capable of maintaining excellent spectral performance under harsh environmental conditions continues to increase globally.
What can you tell us about market trends?
Several trends are shaping the optics market:
- Increasing demand for infrared imaging and sensing systems.
- Growing requirements for MIL-standard durability and environmental resistance.
- Higher expectations for integrated optical and optomechanical solutions rather than standalone components.
- Rising demand from defense and space sectors.
- Greater emphasis on supply chain reliability, traceability, and European manufacturing sources.
- Customers increasingly seek suppliers capable of delivering complete, qualified solutions rather than individual optical elements.
What are the most innovative products/services marketed?
One of Optonas’ most innovative capabilities is the production of high-durability infrared optics that maintain uncompromised spectral performance across demanding SWIR, MWIR, and LWIR applications. While achieving both high optical transmission and stringent durability standards remains a major challenge for many manufacturers, Optonas has developed specialized expertise in this field since 2009.
Over the years, Optonas has continuously refined its infrared coating technologies to achieve substantial improvements in coating durability while preserving the required spectral characteristics. A key driver behind this progress has been the company’s long-term focus on qualification methods derived from demanding laser industry environments, where coating robustness is critical. Through multiple coating design iterations and process optimizations, Optonas progressively increased resistance to abrasion and environmental stress without compromising optical performance.
Today, many of Optonas’ infrared coatings demonstrate “Severe” abrasion resistance not only under conventional standardized inspection conditions but also under more stringent directional LED illumination evaluations, which can reveal surface defects that may remain undetected during traditional inspections. This capability enables the company to combine broadband infrared transmission levels exceeding 95-98% with durability performance that is rarely achieved simultaneously across SWIR, MWIR, and LWIR coating designs.
Another key offering is Optonas’ single-source manufacturing ecosystem, which integrates precision optics, advanced coatings, optomechanical assembly, and qualification testing. This end-to-end process provides customers with complete, fully traceable, and ready-to-install solutions.
What estimations do you have for the second half of 2026?
For the second half of 2026, Optonas expects continued growth driven by defense modernization programs, increasing demand for infrared technologies, and expanding requirements from space and advanced imaging applications. The company anticipates further growth in exports across Europe, NATO countries, Asia, and the United States.
Demand for high-performance, durable infrared optics is expected to remain particularly strong, while customers will continue to seek suppliers capable of delivering integrated optical assemblies with proven quality, traceability, and qualification capabilities. Optonas is well positioned to support customers throughout the entire product lifecycle, from R&D prototypes to high-volume series production, leveraging its established coatings expertise, manufacturing capacity, and vertically integrated approach.
