High-Precision Optical Design for Wide Spectrum Star Trackers | Avantier

Avantier delivers advanced optical system design for wide-spectrum star trackers—enabling high-precision spacecraft attitude determination. We specialize in custom optics for space applications, including reflective, catadioptric, and transmissive systems optimized for operation across the 450–1000 nm spectral range. Our compact, athermalized f/2.8 lens design is tailored for 2048 × 2048 sensors, delivering high-resolution, low-distortion star images critical for accurate celestial navigation. Designed for extreme environments, Avantier’s star tracker optics maintain optical stability across −40 °C to +60 °C and concentrate over 85% of light energy within a 3-pixel radius. Features like telecentric optical paths, wide 26.4° field of view, and space-qualified materials ensure robust performance in demanding aerospace conditions. Avantier’s optical engineering expertise supports the development of high-performance, lightweight lenses for micro- and nano-satellite platforms. Whether your system requires a transmissive lens configuration or a hybrid optical solution, we’re ready to deliver a custom design that meets your mission goals.
