Ilensi zizixhobo zokukhanya eziqhelekileyo, eyona lens ikumgangatho oqhelekileyo yilensi eyiconical, kwaye uninzi lwezi lensi zixhomekeke kwiilensi zeTIR.
Yintoni i-TIR Lens?
I-TIR ibhekisa ku-"Total Internal Reflection", oko kukuthi, ukubonakaliswa kwangaphakathi okupheleleyo, okwakwaziwa ngokuba yi-total reflection, yinto ebonwa ngamehlo. Xa ukukhanya kungena kwi-medium kunye ne-refractive index ephezulu ukuya kwi-medium kunye ne-refractive index ephantsi, ukuba i-angle yesiganeko inkulu kune-angle ethile ebalulekileyo θc (ukukhanya kukude nesiqhelo), ukukhanya okuchasiweyo kuya kunyamalala, kwaye konke ukukhanya kwesiganeko kuya kubonakaliswa kwaye Ungangeni phakathi kunye nesalathisi esisezantsi se-refractive.
TIR ilensiyenziwa ngokusebenzisa umgaqo wokubonakalisa ngokupheleleyo ukuqokelela nokwenza ukukhanya. Uyilo lwayo kukusebenzisa ukukhanya okugqobhozayo ngaphambili, kwaye umphezulu wetapered unokuqokelela kwaye ubonise konke ukukhanya okusecaleni, kunye nokudibana kwezi ntlobo zimbini zokukhanya kunokufumana ipateni yokukhanya egqibeleleyo.
Ukusebenza kwe-TIR lens kunokufikelela ngaphezu kwe-90%, kwaye ineenzuzo zezinga eliphezulu lokusetyenziswa kwamandla okukhanya, ukulahleka okuncinci kokukhanya, indawo encinci yokuqokelela ukukhanya kunye nokufana okulungileyo.
Izinto eziphambili ze-TIR lens yi-PMMA (i-acrylic), eneplastiki enhle kunye nokuhanjiswa kokukhanya okuphezulu (ukuya kwi-93%).
