Unlike fan-based cooling, this passive design achieves rapid and stable thermal equilibrium naturally — without introducing vibration.\u003c\/p\u003e\n\u003ch5 class=\"core-feature-subheading\"\u003eWhy this matters\u003c\/h5\u003e\n\u003cp class=\"core-feature-text\"\u003eOne of the primary limitations in large-aperture telescopes is \"mirror seeing\" — turbulence caused by temperature differences between the mirror and the surrounding air. In changing conditions, a thick solid mirror may never fully reach equilibrium, preventing it from achieving its full optical performance. The sandwich mirror design minimizes this effect, allowing the system to reach optimal performance quickly and consistently, delivering sharper and more stable views without the need for active cooling.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"core-feature\"\u003e\n\u003cdiv class=\"core-feature-icon\"\u003e\u003csvg width=\"24\" height=\"24\" viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"\u003e\u003ccircle cx=\"12\" cy=\"12\" r=\"10\"\u003e\u003c\/circle\u003e\u003cpath d=\"M12 2a14.5 14.5 0 0 0 0 20 14.5 14.5 0 0 0 0-20\"\u003e\u003c\/path\u003e\u003cpath d=\"M2 12h20\"\u003e\u003c\/path\u003e\u003c\/svg\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003ch4 class=\"core-feature-title\"\u003eEnhanced Optical Coatings\u003c\/h4\u003e\n\u003cp class=\"core-feature-text\"\u003e96% enhanced reflective coatings on both primary and secondary mirrors with precision-controlled dielectric layers.
