Avantier offers the latest in high-performance Ritchey-Chrétien telescopes with extensive use of aluminum and silicon carbide (SiC). These telescopes are inherently athermal and lightweight, ensuring consistent imaging performance while reducing launch costs. Custom solutions are available upon request. Ritchey-Chrétien telescopes, part of the Cassegrain system, feature hyperbolic mirrors that minimize optical errors like spherical aberration and coma. While field curvature and astigmatism persist, they offer enhanced off-axis image quality and a wider field of view, making them ideal for astronomy (e.g., Hubble). Though more complex and costly to produce, their ability to eliminate chromatic aberrations makes them valuable for high-quality imaging. Avantier provides custom designs using materials like aluminum and SiC for optimal performance in space.
