Avantier designs and manufactures custom telescope systems for Earth observation, astronomy, remote sensing, surveillance, and scientific payloads.
Ritchey–Chrétien configurations are commonly used, while the optical architecture, aperture, focal length, spectral range, packaging, and interfaces can be customized to mission requirements.
Typical Capabilities
Avantier supports SiC, aluminum, Zerodur, ULE, fused silica, and other optical materials selected according to mission-specific requirements for thermal stability, stiffness, mass, optical performance, manufacturability, and cost.
Material recommendations are developed around the complete optical, thermal, and mechanical design rather than a single property.
Need help selecting the right material for your optical system?
Avantier supports the development of complete optical systems—not only individual components. Our engineers work with customers to define, design, optimize, and realize mission-specific optical payloads around performance, size, mass, thermal behavior, interfaces, and manufacturability.
Each system can be tailored around aperture, focal length, field of view, spectral range, detector format, optical performance, packaging, mass, thermal stability, and mechanical interfaces.
Avantier can support projects from early optical architecture and feasibility studies through detailed engineering, manufacturing, assembly, alignment, metrology, verification, and documentation.

Developing a custom optical payload?
Featured Design Example: A compact, athermalized star-tracker lens designed for a 450–1,000 nm spectral range, an f/2.8 optical system, and a 2,048 × 2,048 detector.
Avantier supports space optical systems from precision fabrication through assembly, alignment, and performance verification. Manufacturing and test plans are developed around the optical design, materials, tolerances, interfaces, and mission environment.
Custom spherical, aspheric, freeform, flat, and SiC optics are produced using advanced machining, polishing, and corrective finishing processes.
Optical components can be integrated into assemblies and complete systems with alignment controlled to meet system-level performance requirements.
Optical performance is verified using measurement methods selected for the component or system geometry and performance requirements.
Environmental testing and qualification support can be provided according to mission requirements and program scope.

Need support taking an optical design into production?
From custom optical components to complete telescope and payload systems, Avantier supports mission-specific requirements for performance, mass, thermal stability, integration, and manufacturability.
Discuss your optical design, component, or system requirements with our engineering team.
How does thermal cycling affect the long-term stability of aluminum optical components?
Thermal cycling can significantly impact the long-term stability of aluminum optical components due to internal residual stresses introduced during manufacturing.
Controlled thermal cycling (stress relief) is often used to reduce these residual stresses, improving dimensional stability over time. This process is typically tailored to the expected operational temperature range of the mission.
When properly treated and designed, aluminum optical components can maintain stable optical performance throughout the mission lifecycle, although they generally exhibit lower thermal stability compared to materials such as SiC or Zerodur.
How should I select the right material for a space optical system?
There is no universally “best” material for space optics. Each material—such as Aluminum, SiC, and Zerodur—offers different trade-offs in thermal behavior, stiffness, weight, manufacturability, and cost.
The optimal choice depends on the specific mission requirements and operating environment. Key factors to consider include:
In practice, material selection is a system-level trade-off rather than a single-parameter optimization. The best material is the one that meets the performance requirements while balancing manufacturability, risk, and cost. Avantier supports material selection and optimization as part of its optical design and engineering services.
When should you involve an optical manufacturing partner in your development process?
The ideal time to engage a manufacturing partner is as soon as you realize you need optics; it is recommended to get involved during the concept or initial design phase.
Waiting beyond the design stage increases the risk of costly iterations, potentially affecting both performance and manufacturability throughout the development process.
How does early manufacturer involvement actually improve the design?
At Avantier, our engineers are part of the conversation from start to finish. They provide feedback on tolerances, materials, surface specifications, and geometries before they are completely finalized. This allows us to help optimize the design for both optical performance and manufacturability, helping you arrive at stronger, more efficient design solutions.
We also understand the importance of your timeline. System requirements, operating environment, and performance targets are all considered from the beginning, reducing surprises during qualification and enabling a smooth transition into production. Coming to us early is what makes an ideal timeline achievable.
What’s the risk of waiting until after the design phase to involve a manufacturing partner?
Designs that have not accounted for manufacturing realities often require redesigns and in aerospace and defense applications, that can be both expensive and time-consuming. Materials, surface specifications, geometries, and engineering capabilities all present challenges that are much easier to address early in the development process.
