Iindaba

Ehlabathini le-lases, ukuphucula umgangatho kunye nokuchaneka kokukhanya kubalulekile kubuninzi bezicelo ukusuka kwi-metrology ukuya kwiinkqubo zonyango. Elinye icandelo elibaluleke kangaka elisetyenziselwa ukunyusa umgangatho we-beam 'yi-beam expander'.

I-expander ye-beam sisixhobo sokukhanya esithatha ukukhanya okudibeneyo kunye nokwandisa ububanzi bayo (ukwahlukana kwe-beam) ngelixa ngaxeshanye kuncitshiswa ukuhlukana kwayo. Ukuguquguquka kwesandisi se-boam kuxhomekeke kumthamo waso wokulungelelanisa nokulawula ukuhlukana kwee-lasers, ukuphucula ukuhambelana kwayo.

Iintlobo zeBeam Expanders

Zimbini iindidi zezandisi ze-beam eziziintloko: ezisisigxina nezilungelelanisiweyo.

I-1, i-Fixed Beam Expander - Njengoko igama libonisa, izandisi ze-beam ezisisigxina zigcina ukuhlukana okungapheliyo kunye nesithuba esisisigxina phakathi kweelensi ezimbini ngaphakathi kwe-expander. Olu hlobo oluthile luthembeke kakhulu kwizicelo ezineendawo ezizinzileyo, ezilawulwayo apho ukulungiswa kungadingekile okanye kungafuneki.

I-2, i-Adjustable Beam Expander - Kwizandisi ze-beam ezilungelelaniswayo, isithuba phakathi kweelensi ezimbini sinokuguqulwa, sivumele abasebenzisi ukuba balungise ukuhlukana kwe-beam njengoko kufuneka. Olu phawu lunikeza uguquko olwandisiweyo kunye nokulungelelaniswa kwezicelo ezineemfuno eziguqukayo.

Izinto eziphathekayo kunye nokuhambelana kweWavelength

I-lens ye-expander ye-boam ngokuqhelekileyo yenziwe nge-ZeSe (Zinc Selenide), i-optical material evumela ukukhanya okubomvu ukuba kudlule ngokufanelekileyo. Kodwa ukubaluleka kwayo kubanzi kunolu. Izandisi ezahlukeneyo zeeplanga zinokusebenza kubude obuninzi bobude, ukonyusa umda woluhlu lokubonwayo.

Umzekelo, iCarmanhaas ibonelela ngeentlobo ezintathu zezandisi zemitha ezinoluhlu olunomtsalane lokuhambelana kwamaza ukusuka kwi-UV (355nm), eluhlaza (532nm), kufutshane ne-infrared (1030-1090nm), phakathi kwe-infrared (9.2-9.7um), ukuya kude- i-infrared (10.6um). Okona kutsala umdla ngakumbi apha kukuba bakwabonelela ngezandisi ezenziwe ngokwezifiso ze-beam zobude obukhethekileyo xa uceliwe.

Ukuqukumbela

Nokuba luhlobo olusisigxina okanye oluhlengahlengiswayo, izandisi zemitha zidlala indima ebalulekileyo ekubumbeni nasekwalathiseni imiqadi yelaser kwizicelo ezahlukeneyo. Ngelixa izandisi ze-beam ezisisigxina zineenzuzo zazo kwiindawo ezizinzileyo, izandisi ze-beam ezihlengahlengiswayo zibonelela ngokuguquguquka okufunekayo kwiimeko eziguqukayo. Nokuba yintoni na imeko, ezi zixhobo zikhusele indawo yazo njengabatshintshi bomdlalo obalulekileyo kwitekhnoloji yelaser.

Ngokusetyenziswa okuhlala kusanda kweelaser kumacandelo ahlukeneyo, imfuno yezandisi ezikhethekileyo kunye nezinokwenziwa ngokwezifiso ziya kwandiswa kwiminyaka ezayo. Kwaye ukuhlangabezana nale mfuno ikhulayo, iinkampani ezifana neCarmanhaas zihlala zijongene nomngeni.
