Muna 1611, muongorori wenyeredzi wekuGermany Kepler akatora zvidimbu zviviri zve lenticular lens sechinangwa uye eyepiece, magnification ari pachena akavandudzwa, gare gare vanhu vakatarisa iyi optical system seKepler telescope.

Muna 1757, Du Grand kuburikidza nekudzidza kwegirazi uye refraction yemvura uye kupararira, akamisa hwaro hwedzidziso yeachromatic lens, uye akashandisa korona nemagirazi egirazi kugadzira achromatic lens.Kubva ipapo, achromatic Refractor Telescope yakatsiva zvachose girazi refu reteresikopu muviri.

Pakupera kwezana ramakore rechigumi nemapfumbamwe, pamwe chete nehunyanzvi hwekugadzira hwakavandudzwa, kugadzira yakakura caliber yerefracting telescope inogoneka, ipapo pane kugadzirwa kwedhiyamita hombe Refractor Telescope climax.Mumwe weainyanya kumiririra aive Ekes teresikopu ye 102 cm dhayamita muna 1897 uye Rick telescope ye 91 cm dhayamita muna 1886.

Refracting telescope ine zvakanakira kureba kwakatarisa, sikero yeplate yakakura, kubhenda kwechubhu hainzwe, inonyanya kukodzera basa rekuyera nyeredzi.Asi inogara iine ruvara rwakasara, panguva imwechete kune ultraviolet, infrared radiation absorption ine simba kwazvo.Kunyange zvazvo girazi hombe rokudira girazi rakaoma, kune teresikopu yeYerkes refracting teresikopu yakavakwa muna 1897, budiriro yasvika pakuguma, kubvira makore aya zana pasina teresikopu inotarisisa yakakura yakaonekwa.
