Tlhaloso ea Polarization
Polarization, eo hape e tsejoang e le leseli la polarized, e bolela leseli le bonahalang e le leqhubu le pota-potileng, le tataiso ea lona ea ho sisinyeha ho ea ka lehlakoreng la phatlalatso.Tataiso ea ho thothomela ea leseli la tlhaho e na le boikhethelo sefofaneng se pota-potileng tataiso ea ho phatlalatsoa;bakeng sa khanya ea polarized, tataiso ea eona ea ho thothomela e lekanyelitsoe ho tataiso e itseng ka nako e itseng.
Polarization Classification
Polarization e ka aroloa ka mefuta e meraro: polarization ea mela, polarization ea elliptical, le polarization e chitja.Ka kakaretso, seo ho thoeng ke polarization se bolela polarization ea mela, e tsejoang hape e le polarization ea sefofane.Ho sisinyeha ha mofuta ona oa leqhubu la leseli ho tsitsitsoe ka tsela e itseng 'me e lula e sa fetohe.Tsela ea eona ea ho hasana sebakeng e latela mokokotlo oa sinusoidal, 'me ponahalo ea eona sefofaneng se pota-potileng ho ea ho tataiso ea ho ata ke mola o otlolohileng.
Sefofane se entsoeng ka tataiso ea ho sisinyeha ha leseli le nang le polarized le tataiso ea ho phatlalatsoa se bitsoa sefofane sa vibration, 'me sefofane se pota-potile tataiso ea ho sisinyeha' me se nang le tataiso ea ho phatlalatsoa se bitsoa sefofane sa polarization.Ho fetisa leseli la tlhaho ka polarizer ho ka hlahisa leseli la polarized linearly.
Mosebetsi oa Polarization
Bophelong ba letsatsi le letsatsi, ho na le mehloli e mengata ea leseli e hlahisang leseli le kotsi, haholo-holo letsatsi.Khanya ea letsatsi e ntša mefuta e meraro ea khanya: leseli le bonahalang, leseli la infrared, le khanya ea ultraviolet (UV).Har'a tsena, khanya ea ultraviolet e ka baka kotsi e tebileng letlalong le mahlo.Leseli le bonahalang le tloha ho 380 ho ea ho 780 nanometers, ha leseli la ultraviolet le arotsoe hape ka UVA, UVB, le UVC, le maqhubu a holimo ho 310nm.UVA, UVB, le UVC ke mahlaseli a kotsi.Ho pepesehela mahlaseli ana nako e telele ho ka baka tšenyo 'meleng.UVB e na le phello e tebileng ponong, hape ke "lehlaseli la tanning" le fifatsang letlalo.Boholo ba likhutlo tsa leihlo li monya mofuta ona oa lebone la UVB, kahoo ho bohlokoa ho thibela mohloli ona oa leseli.

Tlhahiso ea Lilense tsa Polarized
Ka mantsoe a bonolo,lilense tsa polarizedbakeng sa pono e haufi e na le sebopeho se kang sa sandwich (se nang le lesela le ka pele la likhalase tsa letsatsi, lesela le bohareng la likhoele tse nang le polarized, le lera le ka morao la lilense tse bonelang haufi, kaofela li entsoe lalaminated).Lisebelisoa tsa lense tse sebelisoang ka tloaelo li na le index ea refractive ea 1.50 (ho boetse ho na le 1.60, empa e theko e boima haholo).Lilense li batla li le boima ebile li boima, 'me haeba lengolo la ngaka le feta 600 °, bobeli ba botle le boiketlo bo tla ameha haholo.Theko ea lilense tsa polarized bakeng sa pono e haufi e pharaletseng haholo 'me e itšetlehile ka botsitso ba ts'ebetso ea moetsi oa tlhahiso le boleng.

Lisebelisoa tsa Lense tsa Polarized
Ho na le mefuta e mene e tloaelehileng ealilense tsa polarized'marakeng: lilense tsa khalase, lilense tsa resin, lilense tsa PC, le lilense tsa TAC.
① Lilense tsa khalase
Le hoja li sa khone ho hlaba 'me li na le ts'ebetso e ntle ea optical, boima ba tsona le mathata a polokeho li lebisitse ho fokotseha butle-butle ha tšebeliso ea tsona.
② Lilense tsa resin
Li bonolo ho li taka, li bobebe ebile ha li na tšusumetso, e leng se etsang hore e be e 'ngoe ea lisebelisoa tse ka sehloohong bakeng sa likhalase tsa letsatsi tse tsebahalang.Leha ho le joalo, lilense tsa resin li na le tšekamelo ea ho phunya nakong ea ts'ebetso ea edging, 'me li ntse li ka beha likotsi tsa polokeho ha li ka ba le tšusumetso e kholo.

TAC ke e 'ngoe ea lisebelisoa tsa limolek'hule tse pepeneneng.Lilense tsa TAC joalo ka likhalase tsa letsatsi li na le likarolo tse kang acid le alkali resistance, lightweight, le litšenyehelo tse holimo.Leha ho le joalo, lilense tsa TAC li na le khanyetso e fokolang ea abrasion le litšobotsi tse sa tsitsang tsa mahlo.Ho sa tsotellehe theko ea tsona e tlaase, li lahliloe ke bongata ba lihlahisoa tse tsebahalang tsa linaheng tse ling.
