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. |
