A <entity_3> is an <entity_0> using <entity_5>, curved mirrors, or a combination of both to observe distant objects, or various devices used to observe distant objects by their emission, absorption, or reflection of electromagnetic radiation. The earliest existing record of a <entity_3> was a <entity_6> patent submitted to the government in the Netherlands by Middelburg spectacle maker <entity_1> for a refracting <entity_3>. The idea that the objective, or light-gathering element, could be a mirror instead of a <entity_5> was being investigated soon after the <entity_4> of the refracting <entity_3>. The <entity_4> of the achromatic <entity_5> in 1733 partially corrected color aberrations present in the simple <entity_5> and enabled the construction of shorter, more functional refracting telescopes. There are three main optical types: A Fresnel Imager is a proposed ultra-lightweight design for a space <entity_3> that uses a Fresnel <entity_5> to focus light. These are: A <entity_2> is a mechanical structure which supports a <entity_3>.
