Magirazi eAspheric, anozivikanwawo seaspheres, akabuda semutambi mukuru mukuona nekubata nyika, achichinja maonero edu uye kubata nyika. Kusiyana nemagirazi ekare edenderedzwa, magirazi eAspheric anounza nhanho itsva yekunyatsojeka uye kujeka mukugadzira maziso.
1. Chii chinonzi Aspheres?
MaAspheric akasiyana nechimiro chebhora rakafanana. Kusiyana nemalenzi akatenderera, ane kutenderera kwakafanana, maAspheric ane kutenderera kwakasiyana-siyana pamusoro pawo.
Aspherics inoshandisa mabasa epamusoro emasvomhu kuti iwane maumbirwo ayo akasiyana. Nekunyatsoverenga curvature panzvimbo dzakasiyana, mainjiniya e optical anogona kugadzirisa lenzi kuti ikwanise kushandiswa, zvichideredza kukanganiswa uye kuwedzera kunaka kwemufananidzo wese.
2. Mabhenefiti ekushandisa Aspheres
Zvakanakira kuisa ma lenses e aspheric mu optical systems zvakawanda. Chekutanga uye chakakosha, ma aspheric anobvumira kugadziriswa kwakanaka kwe optical aberrations, kuderedza denderedzwa re spheric aberrations, uye kuve nechokwadi chekuti akajeka uye akarurama.mifananidzo, nokudaro zvichivandudza mashandiro.
Magirazi eAspheric anobatsirawo mukuderedza saizi nehuremu hwema optical systems, zvichiita kuti ave akakosha zvikuru mumidziyo midiki yakaita semakamera nemafoni. Pamusoro pezvo, ma lenzi aya anowedzera kushanda zvakanaka kwekuunganidza chiedza, zvichikonzera mifananidzo yakajeka uye yakajeka.
MaAspheric anoisawo simba rawo muzvikamu zvidiki, zvichideredza huwandu hwemasisitimu elaser nemidziyo yemifananidzo. Funga nezvemascanner elaser anotorwa nemaoko achigadzira mapani ezvivakwa zvese neunyanzvi, kana kuti madiki.maendoskopukufamba munzvimbo dzakamanikana mumuviri wemunhu, zvese izvi zvichigoneka nekuda kwechishamiso chidiki cheaspheres. Sainzi iri shure kweaspheres inovhura mukana wemikana yakawanda muminda yakasiyana-siyana kubva pakutora mifananidzo, nyeredzi, uyemafomu e laserkumifananidzo yezvekurapa.
3. Mashandisirwo eAspheres Mumaindasitiri Ese
3.1 Mifananidzo yezvekurapa
Magirazi eAspheric anoshandiswa mumaindasitiri akasiyana-siyana, achiratidza kushanduka-shanduka kwawo. Mukurapa, anoita basa rakakosha mu endoscopes uyezvishandiso zvemifananidzo yekurapa, zvichipa vanachiremba mifananidzo yakajeka yekuongorora chirwere.
3.2 Materesikopu
Nyanzvi dzenyeredzi dzinobatsirwa nekunyatsorongeka kwemaasphere ari mumatelesikopu, zvichibvumira kucherechedzwa kwakadzama. Uyezve, malenzi aya akakosha pakugadzirwa kwemakamera anoshanda zvakanyanya, zvichiita kuti vafotori vemifananidzo vane hunyanzvi vatore nguva zvakajeka.
3.3 Mashandisirwo eLaser
MaAspheres anogona kutarisisa mwenje welaser kuita mitsetse chaiyo, yakatetepa, yakakodzerakucheka nelasermagadzirirwo akaomarara kanakusonaFungidzira marobhoti ekuvhiya achishandisa lasers dzinotungamirirwa neaspheric kuti aite mabasa akaomarara, asingapindi zvakanyanya, kanamaprinta elasermabasa ehunyanzvi anocheka ane ruzivo runoshamisa.
