    Inkomba ye-refractive 1.60 1.59 1.60 1.50 1.52
    Inombolo Abbe 41 28-30 32 58 59

    ·Kokubili inkomba ephezulu ye-refractive kanye nenombolo ye-Abbe ephezulu inikeza ukusebenza kokubona okufana namalensi engilazi.
    ·Impahla yenombolo ye-Abbe ephezulu efana ne-MR-8 inciphisa umphumela we-prism (i-chromatic aberration) yamalensi futhi inikeze ukusetshenziswa okunethezeka kwabo bonke abagqokile.

    Kuyini Ukukhanya Okuluhlaza?

    Ukukhanya kwelanga kuqukethe imisebe yokukhanya ebomvu, ewolintshi, ephuzi, eluhlaza okwesibhakabhaka kanye nemithunzi eminingi yalo mbala ngamunye, kuye ngamandla nobude begagasi bemisebe ngayinye (ebizwa nangokuthi imisebe ye-electromagnetic). Kuhlanganiswe, le spectrum yemisebe yokukhanya enemibala idala lokho esikubiza ngokuthi "ukukhanya okumhlophe" noma ukukhanya kwelanga.

    Ngaphandle kokungena ku-physics eyinkimbinkimbi, kunobudlelwano obuphambene phakathi kwe-wavelength yemisebe yokukhanya kanye nenani lamandla eliwaqukethe. Imisebe yokukhanya enamaza amade uma kuqhathaniswa iqukethe amandla amancane, futhi leyo enobude obufushane bamandla inamandla engeziwe.

    Imisebe ekugcineni ebomvu ye-spectrum yokukhanya ebonakalayo inamaza amade amade, ngakho-ke, amandla amancane. Imisebe esekugcineni okuluhlaza okwesibhakabhaka kwe-spectrum inobude obufushane wamaza namandla engeziwe.

    Imisebe ye-electromagnetic ingale komkhawulo obomvu we-spectrum yokukhanya ebonakalayo ibizwa ngokuthi i-infrared - iyafudumala, kodwa ayibonakali. ("Izibani ezishisayo" ozibonayo zigcina ukudla kufudumele endaweni yangakini yokudla zikhipha imisebe ye-infrared. Kodwa lezi zibani ziphinde zikhiphe ukukhanya okubomvu okubonakalayo ukuze abantu bazi ukuthi zikhanya! Kunjalo nangezinye izinhlobo zezibani zokushisa.)

    Ngakolunye uhlangothi lwe-spectrum yokukhanya ebonakalayo, imisebe yokukhanya eluhlaza okwesibhakabhaka enobude obufushane kakhulu (namandla amakhulu) ngezinye izikhathi ibizwa ngokuthi ukukhanya okuluhlaza okwesibhakabhaka noma oku-violet. Yingakho imisebe ye-electromagnetic engabonakali engale kwe-spectrum yokukhanya ebizwa ngokuthi imisebe ye-ultraviolet (UV).

    Amaphuzu Abalulekile Mayelana Nokukhanya Okuluhlaza

    1. Ukukhanya okuluhlaza kuyo yonke indawo.
    2. Imisebe yokukhanya ye-HEV yenza isibhakabhaka sibukeke siluhlaza.
    3. Iso alilungile kakhulu ekuvimbeni ukukhanya okuluhlaza okwesibhakabhaka.
    4. Ukuchayeka ekukhanyeni okuluhlaza kungase kwenyuse ingozi yokonakala kwe-macular.
    5. Ukukhanya okuluhlaza kunomthelela ekucindezelekeni kwamehlo edijithali.
    6. Ukuvikela ukukhanya okuluhlaza kungase kubaluleke nakakhulu ngemva kokuhlinzwa kwe-cataract.
    7. Akuwona wonke ukukhanya okuluhlaza okwesibhakabhaka okubi.

    Indlela Amalensi Okunciphisa Ukukhanya Okuluhlaza Angasiza Ngayo

    Amalensi okunciphisa ukukhanya okuluhlaza akhiwa kusetshenziswa i-pigment enelungelo lobunikazi engezwa ngqo kumalensi ngaphambi kwenqubo yokusakaza. Lokho kusho ukuthi izinto ezinciphisa ukukhanya okuluhlaza okwesibhakabhaka ziyingxenye yayo yonke impahla yelensi, hhayi nje i-tint noma ukunamathela. Le nqubo enelungelo lobunikazi ivumela ukukhanya okuluhlaza okwesibhakabhaka okunciphisa amalensi ukuthi ahlunge inani eliphezulu lakho kokubili ukukhanya okuluhlaza okwesibhakabhaka nokukhanya kwe-UV.
