Space Optics Simulation & Analysis Methods
Predict on-orbit optical performance
Space optics simulation and analysis are critical to predicting real on-orbit performance.
Spaceborne optical systems rarely fail due to nominal design limitations.
They fail when thermal, mechanical, and environmental effects are insufficiently understood.
Astravon applies specialised analysis methods developed to predict on-orbit optical performance, identify risk drivers early, and support qualification-driven decision making throughout the system lifecycle.
Spaceborne Optical Simulation
We perform optical simulations specifically adapted for spaceborne systems, where performance is constrained by launch loads, thermal gradients, material behaviour, and long-term environmental exposure.
These simulation activities are aligned with system-level requirements and verification objectives rather than nominal performance targets alone.
These space optics simulation and analysis activities include coupled structural-thermal-optical modelling, stray light evaluation, wavefront error prediction, and system-level performance assessment.
STOP Analysis (Structural–Thermal–Optical Performance)
Astravon conducts STOP analyses to evaluate the coupled impact of structural deformation, thermal gradients, and optical sensitivity.
This approach enables:
- Prediction of optical performance across full operational temperature ranges
- Assessment of launch and on-orbit deformation effects
- Identification of alignment and stability drivers at the system level
STOP results are used to inform critical design trade-offs, material selection, and tolerance strategies.
Thermal-Elastic & Opto-Mechanical Modelling
Thermal-elastic modelling is applied to assess deformation, stress, and stability under realistic boundary conditions.
This analytical capability addresses:
- CTE-driven deformation
- Mounting and interface effects
- Gravity release and orientation sensitivity
- Long-term dimensional stability
Results support both design refinement and formal qualification planning.
Stray Light & Contamination Sensitivity Analysis
Stray light analysis is performed to identify unwanted optical paths and sensitivity to internal reflections, scattering, and contamination.
This analyses suppot:
- Baffle and surface treatment strategies
- Low-noise imaging performance
- System-level contrast and signal integrity
This capability is particularly critical for Earth observation, astronomy, and low-signal space instruments.
Wavefront Error & Image Performance Prediction
Wavefront error and image performance are evaluated across across the full spectrum of expected operational conditions.
Rather than reporting isolated metrics, Astravon focuses on:
- Performance margins
- Sensitivity to manufacturing and alignment errors
- Stability over mission lifetime
This approach enables realistic verification planning and reduces late-stage redesign risk.
Analysis as a Decision Tool
Analyses are never treated as academic exercises.
They are used to support engineering decisions, reduce uncertainty, and align design intent with manufacturing and qualification realities.
All analysis activities are documented to provide the necessary evidence for reviews, formal verification, and programme traceability..
