IZinc Selenide (ZnSe)
IiLensi zePlano-Convex

Iilensi zePlano-convex (PCX) ziilensi ezi-positive ezityebileyo embindini kunasemphethweni, xa imitha ye-collimated idlula kuzo, ukukhanya kuyajikela kwindawo ekugxilwe kuyo. Iilensi zePlano-convex zinecala elinye elisicaba kunye nelinye eligobileyo elineradiyasi elungileyo yokugoba. Iilensi zePlano-Convex zinobude bojoliso obulungileyo kwaye zisondela ngendlela efanelekileyo yosetyenziso olungenasiphelo kunye nolunesiphelo lweconjugate. Ezi lens zijolise kwi-collimated beam ukuya kugxininiso lwangasemva kunye nokukhanya okuhambelanayo ukusuka kwindawo yomthombo. Ziyilwe ngokuphambuka okuncinci kwesangqa kwaye zinobude obugxininise obunikwe ngu:
f= R/(n-1),
apho i-R iyindawo egobileyo yenxalenye ye-convex yelensi kwaye n isalathiso sokuchasa.

Iilensi zePlano-convex zihambisa ukuguqulwa okuncinci kwe-spherical xa kugxilwe kwi-infinity (xa into efanekisiweyo ikude kwaye umlinganiselo we-conjugate uphezulu). Ke ngoko zizinto zokuya kwiilensi kwiikhamera nakwiiteleskopu. Ubukhulu bobuchule buphunyezwa xa umphezulu weplano ujongene nenqwelomoya efunekayo, ngamanye amazwi, umphezulu ogobileyo ujongene nomqadi wesiganeko esidityanisiweyo. Iilensi zePlano convex lukhetho olulungileyo lokudityaniswa kokukhanya okanye ukugxila kwizicelo ezisebenzisa ukukhanya kwe-monochromatic, kumashishini afana nemizi-mveliso, amayeza, iirobhothi, okanye ukhuselo. Zilukhetho lwezoqoqosho kwizicelo ezifunayo kuba zilula ukwenza. Njengomgaqo wesithupha, iilensi zeplano-convex zisebenza kakuhle xa into kunye nomfanekiso ukwi-absolute conjugate ratios> 5: 1 okanye <1: 5, ngoko i-spherical aberration, i-coma kunye nokuphazamiseka kuyancitshiswa. Xa ukwandiswa okupheleleyo okufunekayo kuphakathi kwala maxabiso mabini, iilensi zeBi-convex zihlala zifaneleka ngakumbi.

Iilensi ze-ZnSe ziqhele ukusetyenziswa kwi-imaging ye-IR, i-biomedical, kunye nezicelo zomkhosi, zifaneleke kakuhle ukusetyenziswa kunye ne-CO2 lasers yamandla aphezulu ngenxa ye-coefficient ephantsi yokufunxa. Ukongezelela, banokubonelela ngokusasazwa okwaneleyo kummandla obonakalayo ukuvumela ukusetyenziswa kwe-beam yokulungelelanisa ebomvu. IParalight Optics ibonelela ngeZinc Selenide (ZnSe) iiLensi zePlano-Convex (PCV) ezifumaneka nge-broadband AR coating elungiselelwe i-2 µm - 13 μm okanye i-4.5 - 7.5 μm okanye i-8 - 12 μm uluhlu lwe-spectral olufakwe kuzo zombini iindawo. Olu gquba luwunciphisa kakhulu umndilili wembonakalo yesubstrate engaphantsi kwe-3.5%, ivelisa umndilili wosulelo olungaphezulu kwama-92% okanye ama-97% kulo lonke uluhlu lokutyabeka lwe-AR. Jonga ezi Grafu zilandelayo kwiireferensi zakho.
