title="Télescope">télescope</a> destiné exclusivement à l'observation du <a href="/wiki/Soleil" title="Soleil">Soleil</a>. </p><p>Contrairement aux autres télescopes, les télescopes solaires ont généralement des <a href="/wiki/Miroir" title="Miroir">miroirs</a> de petite taille en raison de la grande quantité de <a href="/wiki/Lumi%C3%A8re" title="Lumière">lumière</a> qu'ils reçoivent<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite_crochet">[</span>N 1<span class="cite_crochet">]</span></a></sup>. Pour cette même raison, la plus grande partie du trajet effectué par la lumière à l'intérieur d'un télescope solaire jusqu'aux instruments se fait sous <a href="/wiki/Chambre_%C3%A0_vide" title="Chambre à vide">vide</a>. Ceci permet d'éviter une dégradation des images engendrée par la <a href="/wiki/Turbulence" title="Turbulence">turbulence</a> de l'air créée par la grande quantité d'énergie dégagée par les miroirs. </p><p>Les observatoires solaires au sol observent des <a href="/wiki/Longueur_d%27onde" title="Longueur d'onde">longueurs d'onde</a> dans le <a href="/wiki/Spectre_visible" title="Spectre visible">spectre visible</a>, l'<a href="/wiki/Ultraviolet" title="Ultraviolet">ultraviolet</a> (UV) et le proche-<a href="/wiki/Infrarouge" title="Infrarouge">infrarouge</a> (IR).

D'autres stratégies de limitation de la turbulence peuvent être utilisées. Ainsi, le <i><a href="/wiki/Dutch_Open_Telescope" title="Dutch Open Telescope">Dutch Open Telescope</a></i> est construit sur une charpente ouverte, ce qui permet au vent de passer à travers la structure et par conséquent, refroidir le <a href="/wiki/Miroir_primaire" title="Miroir primaire">miroir primaire</a> du télescope. </p><p>Les télescopes solaires sont également dotés de mécanismes d'arrêt de chaleur (<i>heat stop</i>) afin de limiter cette dernière. En général, le <a href="/wiki/Faisceau" class="mw-disambig" title="Faisceau">faisceau</a> de lumière opère dans un environnement sous vide ou rempli d'<a href="/wiki/H%C3%A9lium" title="Hélium">hélium</a> afin d'éviter la <a href="/wiki/Convection" title="Convection">convection</a> de l'air à l'intérieur du télescope. Ils peuvent également avoir un élément optique principal d'une très grande <a href="/wiki/Longueur_focale" class="mw-redirect" title="Longueur focale">longueur focale</a>, quoique ce n'est pas toujours le cas. </p><p>Puisque le Soleil voyage sur l'<a href="/wiki/%C3%89cliptique" title="Écliptique">écliptique</a>, quelques télescopes solaires sont immobiles (parfois même enterrés) avec comme seule partie mobile un <a href="/wiki/H%C3%A9liostat" title="Héliostat">héliostat</a> qui suit le Soleil.
