I ka makahiki 1611, ua lawe ka German astronomer Kepler i ʻelua ʻāpana lenticular lens ma ke ʻano he pahuhopu a me ka eyepiece, ʻike maopopo ʻia ka hoʻonui ʻana, a ma hope ua manaʻo ka poʻe i kēia ʻōnaehana ʻo Kepler telescope.
I ka makahiki 1757, ua hoʻokumu ʻo Du Grand ma o ke aʻo ʻana i ke aniani a me ka wai refraction a me ka hoʻopuehu ʻana i ke kumu kumu o ka lens achromatic, a ua hoʻohana i ka lei aliʻi a me nā aniani i ka hana ʻana i nā lens achromatic. Mai ia manawa, ua hoʻololi loa ʻo achromatic Refractor Telescope i ke kino telescope aniani lōʻihi.
I ka pau ana o ka umikumamaiwa kenekulia, me ka hana 'enehana i hoʻomaikaʻi, e hana ana i ka nui caliber o ka refracting telescope hiki ke hiki, a laila aia kahi hana o ka nui anawaena Refractor Telescope climax. ʻO kekahi o nā ʻelele nui loa ʻo Ekes telescope o 102 knm anawaena i ka makahiki 1897 a me Rick telescope o 91 knm anawaena i ka makahiki 1886.
Loa'a ka pono o ke telescope refracting i ka lō'ihi o ke alo, nui ka unahi pāha'i, pa'akikī ka piko o ka paipu, kūpono loa no ka hana ana kilo. Akā, loaʻa mau ka waihoʻoluʻu waihoʻoluʻu, i ka manawa like i ka ultraviolet, ikaika loa ka absorption radiation infrared. ʻOiai paʻakikī ka ʻōnaehana hoʻoheheʻe aniani optical nui, i ka Yerkes telescope refracting telescope i kūkulu ʻia i ka makahiki 1897, ua hoʻokō ʻia ka hoʻomohala ʻana, ʻoiai ʻo kēia hoʻokahi haneli mau makahiki ʻaʻole i ʻike ʻia kahi telescope refractive hou aʻe.
