Key Takeaways Risk reduction in space optics is vital since components cannot be repaired once launched.  Avantier ensures reliability through pre-qualification (testing materials, coatings, adhesives, and processes upfront) and designing for qualification (early collaboration, standards compliance, and performance margins).  Supporting practices—thermal-vacuum and vibration testing, contamination control, and full documentation—further strengthen mission assurance.  This integrated, qualification-driven […]

How to Manage Wavefront Error Budgets in Space Telescopes Meeting strict wavefront error (WFE) budgets is essential in the design and manufacturing of space telescope optics. These performance thresholds determine how clearly and accurately a telescope can capture images of distant celestial objects or monitor Earth from orbit. For optical manufacturers, maintaining ultra-low surface figure […]

Key Takeaways Optical systems are vital to ADCS performance in small satellites, enabling precise attitude determination with star trackers, sun sensors, and Earth horizon sensors.  Avantier supports SWaP-constrained missions with compact, radiation-hardened optics, precision assembly, and mission-specific designs. Avantier’s miniaturized, thermally stable components enhance pointing accuracy and environmental resilience.  From beam steering to photon torquers, […]

Key Takeaways Satellite telescope coatings must support wide spectral ranges (UV to LWIR) while enduring radiation, AO exposure, and thermal cycles. AR coatings for lenses and windows require high transmittance, environmental resistance, and minimal outgassing. Gold and silver reflective coatings are essential for high-efficiency IR mirrors in thermal imaging telescopes. AO-resistant layers like ALD-deposited Al₂O₃ […]
