Optical Subassemblies
Optical subassemblies bridge the gap between individual components and fully integrated optical systems.
Astravon provides precision assembly of lenses, mirrors, filters, beamsplitters, and other optical elements into functional optical subassemblies, delivering stable alignment, repeatable performance, and well-defined mechanical interfaces for seamless integration into high-performance optical systems and instruments

Multi-element lens assemblies precisely assembled with controlled optical spacing and alignment, designed for integration into larger optical systems and instruments.
2. Beamsplitter Units
Beamsplitters integrated into precision mechanical mounts, providing stable optical beam separation or combination applications.
3. Dome & Window Subassemblies
Optical domes and windows assembled with mechanical mounting interfaces, designed for environmental protection and optical transmission.
4. Mounted Mirror
Optical mirror elements integrated into mechanical mounts for stable positioning within optical systems.
5. Filter Stack & Holder Assemblies (Available on request)
Multiple optical filters assembled into fixed stacks or holders, custom-configured to meet specific spectral and system-level requirements.
6. Passive Pre-Aligned Optical Units
Optical subassemblies delivered with fixed internal alignment established during assembly, providing repeatable positioning without active adjustment mechanisms.
Typical Assembly Capabilities
Typical capabilities for optical subassembly integration are outlined below. Final specifications are defined according to system-level requirements and application
More stringent alignment tolerances and customized assembly requirements can be supported for mission-specific optical configurations.

Scope & Boundaries
Astravon’s optical subassemblies are provided as building blocks for higher-level integration.
System-level performance, active alignment, and qualification activities are addressed at subsequent integration stages or under separate agreements.

Conventional spherical and rotationally symmetric aspherical lenses are addressed under Refractive Optics due to distinct manufacturing and inspection regimes.
