⊙Aberration
Mune optics, kukanganisa kwe lens system inoita kuti mufananidzo wayo ubve pamitemo yeparaxial imagery.
- Spherical aberration
Kana mwaranzi yechiedza ichiratidzwa nechakaita denderedzwa, maranzi ari pakati chaipo anotariswa pane chinhambwe chakasiyana kubva pagirazi pane (parallel) mwaranzi.MuNewtonian telescopes, magirazi eparaboloidal anoshandiswa, sezvo anotarisisa miranzi yese inofambirana kunzvimbo imwechete.Nekudaro, magirazi eparaboloidal anotambura necoma.
- Chromatic aberration
Uku kukanganiswa kunobva kune akasiyana mavara anouya kuzotarisa pane dzakasiyana nzvimbo.Malenzi ese ane imwe dhigirii yechromatic aberration.Achromatic lenses anosanganisira angangoita maviri mavara anouya kune yakafanana tarisiro.Achromatic refractors inowanzogadziriswa kuti ive negirinhi, uye ingave tsvuku kana yebhuruu inouya kune yakajairika kutarisa, kuregeredza iyo violet.Izvi zvinotungamira kune iwo akajeka violet kana ebhuruu halos akatenderedza Vega kana mwedzi, sezvo girinhi uye dzvuku mavara ari kuuya kuzotarisa, asi sezvo iyo yeviolet kana yebhuruu isiri, iwo mavara haana kutariswa uye akasviba.
- Coma
Iyi i-off-axis aberration, kureva, zvinhu chete (nekuda kwedu, nyeredzi) izvo zvisiri pakati pemufananidzo zvinokanganiswa.Mwaranzi yemwenje inopinda muoptical system iri kure nepakati pakona inonangana nenzvimbo dzakasiyana pane inopinda muoptical system iri padyo kana pedyo neakisi yemaziso.Izvi zvinoguma nemufananidzo wakafanana nekometi uumbwe kure nepakati pemufananidzo.
- Munda curvature
Munda urimubvunzo ndiwo chaiwo wakanangana nendege, kana ndege iri pakatarisana nechiridzwa chemaziso.Pakutora mifananidzo, ndege iyi ndeye planar (yakafuratira), asi mamwe masisitimu emeso anopa ndege dzakakomberedzwa.Muchokwadi, materusikopu mazhinji ane imwe dhigirii yekumisikidza kwemunda.Iyo dzimwe nguva inodaidzwa kuti Petzval Field Curvature, sezvo ndege inowira mufananidzo inodaidzwa kuti Petzval pamusoro.Kazhinji, kana ichinge ichidanwa seyakatsauka, iyo curvature inoenderana nemufananidzo wese, kana kutenderera symmetric nezve yekuona axis.
- Kukanganisa - mbiya
Kuwedzera kwekukura kubva pakati kusvika kumucheto kwechifananidzo.Sikweya inoguma yaita kunge yakazvimba, kana kuti mbiya.
- Kukanganisa - pincushiond
Kuderera kwekukura kubva pakati kusvika kumucheto kwechifananidzo.Sikweya inoguma yaita seyakapinyiwa, kunge pincushion.
- Ghosting
Chaizvoizvo kuratidzwa kwemufananidzo wekunze-kwe-munda kana mwenje mundima yekuona.Kazhinji chete dambudziko rine zvisizvo Baffled eyepieces uye zvinhu zvinopenya.
- itsvo beam effect
Iyo yakashata Televue 12mm Nagler Type 2 dambudziko.Kana ziso rako risina kunyatsomira pakati peFIELD LENS, uye perpendicular kune optical axis, chikamu chemufananidzo chine bhinzi nhema inovhara chikamu chemaonero ako.
⊙Achromat
Lenzi inoumbwa nezvinhu zviviri kana kupfuura, kazhinji yekorona uye girazi redombo, yakagadziridzwa kuti chromatic aberration iremekedzwe kune maviri akasarudzwa wavelengths.Iyo inozivikanwawo se achromatic lens.

⊙Astigmatism
A lens aberration iyo inoguma mune tangential uye sagittal mufananidzo ndege kupatsanurwa axially.Iyi ndiyo imwe nzira yekumisikidza kwemunda uko munda wekuona wakakomberedzwa zvakasiyana kune maranzi echiedza achipinda muhurongwa pane kwakasiyana.Nezve telescope optics, ASTIGMATISM inobva mugirazi kana lenzi ine yakati siyanei FOCAL LENGTH kana ikayerwa nenzira imwe mhiri kwendege yemufananidzo, pane kana kuyerwa perpendicular kuenda ikoko.
