Yini isihlungi esibonakalayo?

Kunezinhlobo ezintathu zezihlungi zamehlo: izihlungi ze-shortpass, izihlungi ze-longpass, nezihlungi ze-bandpass.Isihlungi se-shortpass sivumela ubude begagasi obufushane kunobude obunqunyiwe ukuthi budlule, kuyilapho sehlisa amaza amade amade.Ngokuphambene, isihlungi se-longpass sidlulisa amaza amade amaza kune-wavelength enqunyiwe ngenkathi sivimba ubude bezaza obufushane.Isihlungi se-bandpass yisihlungi esivumela ububanzi obuthile, noma “ibhendi”, yobude begagasi ukuthi budlule, kodwa sinciphise wonke amaza amaza azungeze ibhendi.Isihlungi se-monochromatic isimo esidlulele sesihlungi se-bandpass, esidlulisela kuphela ububanzi obuncane kakhulu bamaza.

Isihlungi esibonakalayo sidlulisa ngokukhetha ingxenye eyodwa ye-optical spectrum, kuyilapho senqaba ezinye izingxenye.Okuvame ukusetshenziswa ku-microscopy, i-spectroscopy, ukuhlaziywa kwamakhemikhali, nombono womshini.
Izihlungi ze-Optical amadivayisi angenzi lutho avumela ukudluliswa kobude obuthile begagasi noma isethi yamaza okukhanya okukhanya.Kunezigaba ezimbili zokuhlunga okubonakalayo okunezindlela ezihlukene zokusebenza: izihlungi ezimuncayo nezihlungi ze-dichroic.
Izihlungi ezimuncwayo zinoqweqwe lwezinto ezihlukene zemvelo nezingaphili ezimunca ubude obuthile bokukhanya, ngaleyo ndlela zivumele ubude obufunekayo ukuthi budlule.Njengoba bemunca amandla okukhanya, izinga lokushisa lalezi zihlungi liyakhula ngesikhathi sokusebenza.Ziyizihlungi ezilula futhi zingangezwa kumapulasitiki ukwenza izihlungi ezingabizi kakhulu kunezakwabo ezisekelwe engilazini.Ukusebenza kwalezi zihlungi akuncikile ku-engeli yesibani sesigameko kodwa ezimpahleni zezinto ezakha izihlungi.Ngenxa yalokho, ayizihlungi ezinhle zokusebenzisa uma ukukhanya okubonisiwe kwe-wavelength engadingeki kungabangela umsindo kusignali yokubona.
Izihlungi ze-Dichroic ziyinkimbinkimbi ekusebenzeni kwazo.Aqukethe uchungechunge lwama-optical coatings anogqinsi olunembile oludizayinelwe ukukhombisa amaza angamaza angafuneki futhi adlulisele ububanzi obufunekayo be-wavelength.Lokhu kufinyelelwa ngokubangela ubude begagasi obufunwayo buphazamiseke ngendlela eyakhayo ohlangothini lokudlulisela lwesihlungi, kuyilapho amanye amaza amaza aphazamisa ngendlela eyakhayo ohlangothini olukhanyayo lwesihlungi.
