Silicon lense ke lense ea optical e entsoeng ka silicon.Silicon (Si) ke lisebelisoa tsa kristale tse sebelisoang hangata lits'ebetsong tsa infrared optical tse sebetsang ho 3 ho 5µm spectral band.Lenane la eona la refractive le haufi le 3.4 ho pholletsa le mefuta eohle.E na le likhoele tse tlase haholo lipakeng tsa lisebelisoa tse tloaelehileng tsa infrared, e leng halofo feela ea Ge, GaAs le ZnSe.Kahoo thepa ea silicon ke khetho e nepahetseng bakeng sa sistimi e nang le mathata a boima.Silicon e boetse e thata ebile e theko e tlaase ho feta lisebelisoa tse ngata tse tloaelehileng tsa infrared, fokotsa litšenyehelo tsa thepa ha li ntse li eketsa litšenyehelo tsa ho etsa thepa ka nako e le 'ngoe.
Silicon e loketse kopo ea MWIR empa ka lebaka la ho monya ho matla ka holimo ho 6 micron, ha e tšoanelehe bakeng sa ts'ebeliso ea LWIR.E ka boela ea sebelisoa e le seipone sa seipone bakeng sa ts'ebeliso ea laser ka lebaka la conductivity ea eona ea mocheso, boima bo bobebe le boima.
Wavelength Infrarede ka etsa mefuta e fapaneng ea lense ea silicon kasefofane, sekontiri, sekontiri, bokaholimo ba sepakapaka le libaka tse fapaneng.Silicon e tumme haholo bakeng sa litsamaiso tse sebetsang sebakeng sa 3-5µm spectral, tse nang le li-anti-reflective coatings (AR coating), phetisetso e tloaelehileng e ka tlisoa ho 98%.Re ka boela ra sebelisa coating ea daemane e kang ea daemane (DLC coating) kapa coating e phahameng e tšoarellang (HD coating) holim'a lense ho fana ka tšireletso e eketsehileng khahlanong le mongoapo le tšusumetso.
Wavelength infrarede etsa lense ea silicon ea boleng bo holimo le ea aspheric.Li ka tsepamisa kapa tsa kheloha leseli le kenang ho fihlela litlhoko tse khethehileng tsa sistimi ea infrared.
