N'afọ 1611, onye Germany na-enyocha mbara igwe Kepler weghaara oghere abụọ nke lens lenticular dị ka ihe ebumnobi na anya anya, a na-emewanyewanyewanye ike ahụ n'ụzọ doro anya, mgbe e mesịrị ndị mmadụ weere usoro a anya dị ka telescope Kepler.

Na 1757, Du Grand site n'ịmụ banyere iko na mmiri refraction na dispersion, guzobe theoretical ntọala nke achromatic oghere, na-eji okpueze na flint iko na-arụpụta achromatic lens. Kemgbe ahụ, telescope achromatic Refractor nọchiri anya igwe teliskop ogologo ogologo kpamkpam.

Na njedebe nke narị afọ nke iri na itoolu, yana mmepụta teknụzụ na-eme ka ọ dịkwuo mma, na-eme ka teliskop refracting ka ukwuu, mgbe ahụ, a na-emepụta nnukwu dayameta Refractor Telescope climax. Otu n'ime ndị nnọchi anya ya bụ teliskop Ekes nke dayameta 102 cm na 1897 na telescope Rick nke dayameta 91 cm na 1886.

Igwe teliskop refracting nwere uru nke ogologo ebe a na-elekwasị anya, ọnụ ọgụgụ efere dị ukwuu, na-ehulata tube adịghị enwe mmetụta, kacha dabara adaba maka ọrụ nha nke mbara igwe. Ma ọ na-enwe mgbe niile agba fọdụrụnụ, n'otu oge ahụ na ultraviolet, infrared radieshon absorption dị ike nke ukwuu. Ọ bụ ezie na nnukwu usoro ịwụsa ugegbe anya siri ike, na teliskop Yerkes nke na-emegharị teliskop e wuru na 1897, mmepe eruola n'isi, ebe ọ bụ na otu narị afọ a ọ nweghị teliskop na-emegharị ahụ ka ukwuu pụtara.
